Hi, OK thanks! I saw that after upgrading to 4.0.5 from 4.0.4 the DB already dropped with around 500MB directly and is now at 2GB smaller. Does this sounds familiar to you with other settings in 4.0.5 ?

It should not take a full hour to migrate as we already made incremental synchronization with the current system but better keep some margin. The system will then take over delivery of the mails but might be a bit slow at first as it needs to reindex all the archived mails (which might take a few hours). To manage your subscriptions and delivery settings you can do this easily on the much nicer web interface (https://lists.ovirt.org) There is a notion of account so you don't need to login separately for each ML.= You can Sign In using Fedora, GitHub or Google or create a local account if you prefer. Please keep in mind signing in with a different method would create separate accounts (which cannot be merged at the moment). But you can easily link your account to other authentication methods in your settings (click on you name in the up-right corner -> Account -> Account Connections). As for the original mail archives, because the previous system did not have stable URLs, we cannot create mappings to the new pages. We decided to keep the old archives around on the same URL (/pipermail), so the Internet links would still work fine. Hope you'd be happy with the new system. \_o< --AUFHCWPQQknM84fF2kF4uGjIv4blC9bMv-- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEcpcqg+UmRT3yiF+BVen596wcRD8FAlmwx0MACgkQVen596wc RD9LTQ/+LtUncsq9K8D/LX8wqUTd6VyPwAD5UnAk5c3H/2tmyVA0u7FIfhEyPsXs Z//LE9FEneTDqDVRi1Dw9I54K0ZwxPBemi71dXfwgBI7Ay0ezkbLWrA168Mt9spE tHAODEuxPt2to2aqaS4ujogrkp/gvEP8ILoxPEqoTPCJ/eDTPAu/I1a2JzjMPK3n 2BBS6D8z0TLAf7w1n72TsgX2QzJW57ig/0HELyjvat2/K8V3HSrkwiKlsdULQDWe zB+aMde7r6UoyVKHqlu4asTl2tU/lGZ+e31Hd9Bnx1/oZOJdzslGOhEo9Qoz6763 AHWU9LKiK4NtxYHj2UQTWhndr8PiTtTmR73eIDmkb0cuRXxzjl9VQbwYJ0Kbrmfp attTqpc2CnEojTNXUUNSmNxotZoYXZiX8ZvjPfSgRVr15TUYujzlOfG+lUynbQMV 9rQ9/m58wgwYUymMpOIsRGaIcAKzjm+WpuuVnO+bS2AfmcBkGMQRoIhfV+3SkS8q kT9cDXgcDZOzVFcnZZB4EjbycMcPgZDcoHxU88VdYH+jFJYvvb21esgswVF/wJ2Z uEI/chp4+ADaQhl8ehZNWMSZq125v6SeirPhBNgLG7zFVZI1S9Tm/6qFmH+ajQY7 nCk1X9HZlB1ubex1X+HibRz9QKOilkMgkADyJ4yMDckwYj93sx0= =l6uN -----END PGP SIGNATURE----- --IfGqXrbgT9wNNdIsvS8kI8WdhEQHlgkiq--

vdsClient is removed and replaced by vdsm-client
by Irit Goihman 16 Apr '18

16 Apr '18

Hi All, vdsClient will be removed from master branch today. It is using XMLRPC protocol which has been deprecated and replaced by JSON-RPC. A new client for vdsm was introduced in 4.1: vdsm-client. This is a simple client that uses JSON-RPC protocol which was introduced in ovirt 3.5. The client is not aware of the available methods and parameters, and you should consult the schema [1] in order to construct the desired command. Future version should parse the schema and provide online help. If you're using vdsClient, we will be happy to assist you in migrating to the new vdsm client. *vdsm-client usage:* vdsm-client [-h] [-a ADDRESS] [-p PORT] [--unsecure] [--timeout TIMEOUT] [-f FILE] namespace method [name=value [name=value] ...] Invoking simple methods: # vdsm-client Host getVMList ['b3f6fa00-b315-4ad4-8108-f73da817b5c5'] For invoking methods with many or complex parameters, you can read the parameters from a JSON format file: # vdsm-client Lease info -f lease.json where lease.json file content is: { "lease": { "sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2", "lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5" } } It is also possible to read parameters from standard input, creating complex parameters interactively: # cat <<EOF | vdsm-client Lease info -f - { "lease": { "sd_id": "75ab40e3-06b1-4a54-a825-2df7a40b93b2", "lease_id": "b3f6fa00-b315-4ad4-8108-f73da817b5c5" } } EOF *Constructing a command from vdsm schema:* Let's take VM.getStats as an example. This is the entry in the schema: VM.getStats: added: '3.1' description: Get statistics about a running virtual machine. params: - description: The UUID of the VM name: vmID type: *UUID return: description: An array containing a single VmStats record type: - *VmStats namespace: VM method name: getStats params: vmID The vdsm-client command is: # vdsm-client VM getStats vmID=b3f6fa00-b315-4ad4-8108-f73da817b5c5 *Invoking getVdsCaps command:* # vdsm-client Host getCapabilities Please consult vdsm-client help and man page for further details and options.

Passing VLAN trunk to VM
by Simon Vincent 26 Mar '18

26 Mar '18

Is it possible to pass multiple VLANs to a VM (pfSense) using a single virtual NIC? All my existing oVirt networks are setup as a single tagged VLAN. I know this didn't used to be supported but wondered if this has changed. My other option is to pass each VLAN as a separate NIC to the VM however if I needed to add a new VLAN I would have to add a new interface and reboot the VM as hot-add of NICs is not supported by pfSense.

Hello, I have one cluster with two hosts with power management correctly configured and one virtual machine with HostedEngine over shared storage with FiberChannel. When i shutdown the network of host with HostedEngine VM, it should be possible the HostedEngine VM migrate automatically to another host? What is the expected behaviour on this HA scenario?

oVIRT 4.1 / iSCSI Multipathing
by Devin Acosta 05 Mar '18

05 Mar '18

I am using the latest release of oVIRT 4.1.3, and I am connecting a Dell Compelent SAN that has 2 fault domains each on a separate VLAN that I have attached to oVIRT. From what I understand I am suppose to go into “iSCSI Multipathing” option and add a BOND of the iSCSI interfaces. I have done this selecting the 2 logical networks together for iSCSI. I notice that there is an option below to select Storage Targets but if I select the storage targets below with the logical networks the the cluster goes crazy and appears to be mad. Storage, Nodes, and everything goes offline even thought I have NFS also attached to the cluster. How should this best be configured. What we notice that happens is when the server reboots it seems to log into the SAN correctly but according the the Dell SAN it is only logged into once controller. So only pulls both fault domains from a single controller. Please Advise. Devin

when creating VMs, I don't want hosted_storage to be an option
by Mike Farnam 09 Feb '18

09 Feb '18

Hi All - Is that a way to mark hosted_storage somehow so that it’s not available to add new VMs to? Right now it’s the default storage domain when adding a VM. At the least, I’d like to make another storage domain the default. Is there a way to do this? Thanks

qemu-kvm images corruption
by Nicolas Ecarnot 06 Feb '18

06 Feb '18

TL;DR: How to avoid images corruption? Hello, On two of our old 3.6 DC, a recent series of VM migrations lead to some issues : - I'm putting a host into maintenance mode - most of the VM are migrating nicely - one remaining VM never migrates, and the logs are showing : * engine.log : "...VM has been paused due to I/O error..." * vdsm.log : "...Improbable extension request for volume..." After digging amongst the RH BZ tickets, I saved the day by : - stopping the VM - lvchange -ay the adequate /dev/... - qemu-img check [-r all] /rhev/blahblah - lvchange -an... - boot the VM - enjoy! Yesterday this worked for a VM where only one error occurred on the qemu image, and the repair was easily done by qemu-img. Today, facing the same issue on another VM, it failed because the errors were very numerous, and also because of this message : [...] Rebuilding refcount structure ERROR writing refblock: No space left on device qemu-img: Check failed: No space left on device [...] The PV/VG/LV are far from being full, so I guess I don't where to look at. I tried many ways to solve it but I'm not comfortable at all with qemu images, corruption and solving, so I ended up exporting this VM (to an NFS export domain), importing it into another DC : this had the side effect to use qemu-img convert from qcow2 to qcow2, and (maybe?????) to solve some errors??? I also copied it into another qcow2 file with the same qemu-img convert way, but it is leading to another clean qcow2 image without errors. I saw that on 4.x some bugs are fixed about VM migrations, but this is not the point here. I checked my SANs, my network layers, my blades, the OS (CentOS 7.2) of my hosts, but I see nothing special. The real reason behind my message is not to know how to repair anything, rather than to understand what could have lead to this situation? Where to keep a keen eye? -- Nicolas ECARNOT

[vdsm] status update: running containers alongside VMs
by Francesco Romani 05 Jan '18

05 Jan '18

Hi everyone, I'm happy to share some progress about the former "convirt"[1] project, which aims to let Vdsm containers alongside VMs, on bare metal. In the last couple of months I kept updating the patch series, which is approaching the readiness to be merged in Vdsm. Please read through this mail to see what the patchset can do now, how you could try it *now*, even before it is merged. Everyone is invited to share thoughts and ideas about how this effort could evolve. This will be a long mail; I will amend, enhance and polish the content and make a blog post (on https://mojaves.github.io) to make it easier to consume and to have some easy-to-find documentation. Later on the same content will appear also on the oVirt blog. Happy hacking! +++ # How to try how the experimental container support for Vdsm. Vdsm is gaining *experimental* support to run containers alongside VMs. Vdsm had since long time the ability to manage VMs which run containers, and recently gained support for [atomic guests](http://www.projectatomic.io/blog/2015/01/running-ovirt-guest-agent-as-privileged-container/). With the new support we are describing, you will be able to manage containers with the same, proven infrastructure that let you manage VMs. This feature is currently being developed and it is still not merged in the Vdsm codebase, so some extra work is needed if you want to try it out. We aiming to merge it in the oVirt 4.1.z cycle. ## What works, aka what to expect The basic features are expected to work: 1. Run any docker image on the public docker registry 2. Make the container accessible from the outside (aka not just from localhost) 3. Use file-based storage for persistent volumes ## What does not yet work, aka what NOT to expect Few things are planned and currently under active development: 1. Monitoring. Engine will not get any update from the container besides "VM" status (Up, Down...) One important drawback is that you will not be told the IP of the container from Engine, you will need to connect to the Vdsm host to discover it using standard docker tools. 2. Proper network integration. Some steps still need manual intervention 3. Stability and recovery - it's pre-alpha software after all! :) ## 1. Introduction and prerequisites Trying out container support affects only the host and the Vdsm. Besides add few custom properties (totally safe and supported since early 3.z), there are zero changes required to the DB and to Engine. Nevertheless, we recommend to dedicate one oVirt 4.y environment, or at least one 4.y host, to try out the container feature. To get started, first thing you need is to setup a vanilla oVirt 4.y installation. We will need to make changes to the Vdsm and to the Vdsm host, so hosted engine and/or oVirt node may add extra complexity, better to avoid them at the moment. The reminder of this tutorial assumes you are using two hosts, one for Vdsm (will be changed) and one for Engine (will require zero changes); furthermore, we assume the Vdsm host is running on CentOS 7.y. We require: - one test host for Vdsm. This host need to have one NIC dedicated to containers. We will use the [docker macvlan driver](https://raesene.github.io/blog/2016/07/23/Docker-MacVLAN/), so this NIC *must not be* part of one bridge. - docker >= 1.12 - oVirt >= 4.0.5 (Vdsm >= 4.18.15) - CentOS >= 7.2 Docker >= 1.12 is avaialable for download [here](https://docs.docker.com/engine/installation/linux/centos/) Caveats: 1. docker from official rpms conflicts con docker from CentOS, and has a different package name: docker-engine vs docker. Please note that the kubernetes package from CentOS, for example, require 'docker', not 'docker-engine'. 2. you may want to replace the default service file [with this one](https://github.com/mojaves/convirt/blob/master/patches/centos72/system… and to use this [sysconfig file](https://github.com/mojaves/convirt/blob/master/patches/centos72/syste…. Here I'm just adding the storage options docker requires, much like the CentOS docker is configured. Configuring docker like this can save you some troubleshooting, especially if you had docker from CentOS installed on the testing box. ## 2. Patch Vdsm to support containers You need to patch and rebuild Vdsm. Fetch [this patch](https://github.com/mojaves/convirt/blob/master/patches/vdsm/4.18.15.… and apply it against Vdsm 4.18.15.1. Vdsm 4.18.15.{1,2,...} are supported as well. Rebuild Vdsm and reinstall on your box. [centos 7.2 packages are here](https://github.com/mojaves/convirt/tree/master/rpms/centos72) Make sure you install the Vdsm command line client (vdsm-cli) Restart *both* Vdsm and Supervdsm, make sure Engine still works flawlessly with patched Vdsm. This ensure that no regression is introduced, and that your environment can run VMs just as before. Now we can proceed adding the container support. start docker: # systemctl start docker-engine (optional) # systemctl enable docker-engine Restart Vdsm again # systemctl restart vdsm Now we can check if Vdsm detects docker, so you can use it: still on the same Vdsm host, run $ vdsClient -s 0 getVdsCaps | grep containers containers = ['docker', 'fake'] This means this Vdsm can run containers using 'docker' and 'fake' runtimes. Ignore the 'fake' runtime; as the name suggests, is a test driver, kinda like /dev/null. Now we need to make sure the host network configuration is fine. ### 2.1. Configure the docker network for Vdsm PLEASE NOTE that the suggested network configuration assumes that * you have one network, `ovirtmgmt` (the default one) you use for everything * you have one Vdsm host with at least two NICs, one bound to the `ovirtmgmt` network, and one spare _This step is not yet automated by Vdsm_, so manual action is needed; Vdsm will take care of this automatically in the future. You can use [this helper script](https://github.com/mojaves/convirt/blob/master/patches/vdsm/cont-se…, which reuses the Vdsm libraries. Make sure you have patched Vdsm to support container before to use it. Let's review what the script needs: # ./cont-setup-net -h usage: cont-setup-net [-h] [--name [NAME]] [--bridge [BRIDGE]] [--interface [INTERFACE]] [--gateway [GATEWAY]] [--subnet [SUBNET]] [--mask [MASK]] optional arguments: -h, --help show this help message and exit --name [NAME] network name to use --bridge [BRIDGE] bridge to use --interface [INTERFACE] interface to use --gateway [GATEWAY] address of the gateway --subnet [SUBNET] subnet to use --mask [MASK] netmask to use So we need to feed --name, --interface, --gateway, --subnet and optionally --mask (default, /24, is often fine). For my case the default mask was indeed fine, so I used the script like this: # ./cont-setup-net --name ovirtmgmt --interface enp3s0 --gateway 192.168.1.1 --subnet 192.168.1.0 Thhis is the output I got: DEBUG:virt.containers.runtime:configuring runtime 'docker' DEBUG:virt.containers.command:* calling ['/bin/docker', 'network', 'inspect', 'ovirtmgmt'] Error: No such network: ovirtmgmt DEBUG:virt.containers.command:* called ['/bin/docker', 'network', 'inspect', 'ovirtmgmt'] DEBUG:virt.containers.runtime.Docker:config: cannot load 'ovirtmgmt', ignored DEBUG:virt.containers.command:* calling ['/bin/docker', 'network', 'create', '-d', 'macvlan', '--subnet=192.168.1.0/24', '--gateway=192.168.1.1', '--ip-range=192.168.1.0/24', '-o', 'parent=enp3s0', 'ovirtmgmt'] DEBUG:virt.containers.command:* called ['/bin/docker', 'network', 'create', '-d', 'macvlan', '--subnet=192.168.1.0/24', '--gateway=192.168.1.1', '--ip-range=192.168.1.0/24', '-o', 'parent=enp3s0', 'ovirtmgmt'] DEBUG:virt.containers.runtime:configuring runtime 'fake' You can clearly see what the script did, and why it needed the root privileges. Let's deoublecheck using the docker tools: # docker network ls NETWORK ID NAME DRIVER SCOPE 91535f3425a8 bridge bridge local d42f7e5561b5 host host local 621ab6dd49b1 none null local f4b88e4a67eb ovirtmgmt macvlan local # docker network inspect ovirtmgmt [ { "Name": "ovirtmgmt", "Id": "f4b88e4a67ebb7886ec74073333d613b1893272530cae4d407c95ab587c5fea1", "Scope": "local", "Driver": "macvlan", "EnableIPv6": false, "IPAM": { "Driver": "default", "Options": {}, "Config": [ { "Subnet": "192.168.1.0/24", "IPRange": "192.168.1.0/24", "Gateway": "192.168.1.1" } ] }, "Internal": false, "Containers": {}, "Options": { "parent": "enp3s0" }, "Labels": {} } ] Looks good! the host configuration is completed. Let's move to the Engine side. ## 3. Configure Engine As mentioned above, we need now to configure Engine. This boils down to: Add a few custom properties for VMs: In case you were already using custom properties, you need to amend the command line to not overwrite your existing ones. # engine-config -s UserDefinedVMProperties='volumeMap=^[a-zA-Z_-]+:[a-zA-Z_-]+$;containerImage=^[a-zA-Z]+(://|)[a-zA-Z]+$;containerType=^(docker|rkt)$' --cver=4.0 It is worth stressing that while the variables are container-specific, the VM custom properties are totally inuntrusive and old concept in oVirt, so this step is totally safe. Now restart Engine to let it use the new variables: # systemctl restart ovirt-engine The next step is actually configure one "container VM" and run it. ## 4. Create the container "VM" To finally run a container, you start creating a VM much like you always did, with few changes 1. most of the hardware-related configuration isn't relevant for container "VMs", besides cpu share and memory limits; this will be better documented in the future; unneeded configuration will just be ignored 2. You need to set some custom properties for your container "VM". Those are actually needed to enable the container flow, and they are documented in the next section. You *need* to set at least `containerType` and `containerImage`. ### 4.2. Custom variables for container support The container support needs some custom properties to be properly configured: 1. `containerImage` (*needed* to enable the container system). Just select the target image you want to run. You can use the standard syntax of the container runtimes. 2. `containerType` (*needed* to enable the container system). Selects the container runtime you want to use. All the available options are always showed. Please note that unavailable container options are not yet grayed out. If you *do not* have rkt support on your host, you still can select it, but it won't work. 3. `volumeMap` key:value like. You can map one "VM" disk (key) to one container volume (value), to have persistent storage. Only file-based storage is supported. Example configuration: `containerImage = redis` `containerType = docker` `volumeMap = vda:data` (this may not be needed, and the volume label is just for illustrative purposes) ### 4.2. A little bit of extra work: preload the images on the Vdsm host This step is not needed by the flow, and will be handled by oVirt in the future. The issue is how the container image are handled. They are stored by the container management system (rkt, docker) on each host, and they are not pre-downloaded. To shorten the duration of the first boot, you are advised to pre-download the image(s) you want to run. For example ## on the Vdsm host you want to use with containers # docker pull redis ## 5. Run the container "VM" You are now all set to run your "VM" using oVirt Engine, just like any existing VM. Some actions doesn't make sense for a container "VM", like live migration. Engine won't stop you to try to do those actions, but they will fail gracefully using the standard errors. ## 6. Next steps What to expect from this project in the future? For the integration with Vdsm, we want to fix the existing known issues, most notably: * add proper monitoring/reporting of the container health * ensure proper integration of the container image store with oVirt storage management * streamline the network configuration What is explicitely excluded yet is any Engine change. This is a Vdsm-only change at the moment, so fixing the following is currently unplanned: * First and foremost, Engine will not distinguish between real VMs and container VMs. Actions unavailable to container will not be hidden from UI. Same for monitoring and configuration data, which will be ignored. * Engine is NOT aware of the volumes one container can use. You must inspect and do the mapping manually. * Engine is NOT aware of the available container runtimes. You must select it carefully Proper integration with Engine may be added in the future once this feature exits from the experimental/provisional stage. Thanks for reading, make sure to share your thoughts on the oVirt mailing lists! +++ [1] we keep calling it that way _only_ internally, because it's a short name we are used to. After the merge/once we release it, we will use a different name, like "vdsm-containers" or something like it. -- Francesco Romani Red Hat Engineering Virtualization R & D Phone: 8261328 IRC: fromani

Empty cgroup files on centos 7.3 host

Looking at this post: http://lists.ovirt.org/pipermail/users/2017-January/079011.html this should work. Is this normal on centos 7.3 with oVirt installed? How can I get those values, without monitoring all VMs directly? oVirt Version we use: 4.1.1.8-1.el7.centos BR Florian

Engine crash, storage won't activate, hosts won't shutdown, template locked, gpu passthrough failed
by M R 09 Oct '17

09 Oct '17

Hello! I have been using Ovirt for last four weeks, testing and trying to get things working. I have collected here the problems I have found and this might be a bit long but help to any of these or maybe to all of them from several people would be wonderful. My version is ovirt node 4.1.5 and 4.1.6 downloaded from website latest stable release at the time. Also tested with CentOS minimal +ovirt repo. In this case, 3. is solved, but other problems persist. 1. Power off host First day after installing ovirt node, it was able to reboot and shutdown clean. No problems at all. After few days of using ovir, I have noticed that hosts are unable to shutdown. I have tested this in several different ways and come to the following conclusion. IF engine has not been started after boot, all hosts are able to shutdown clean. But if engine is started even once, none of the hosts are able to shutdown anymore. The only way to get power off is to unplug or press power button for a longer time as hard reset. I have failed to find a way to have the engine running and then shutdown host. This effects to all hosts in the cluster. 2. Glusterfs failed Every time I have booted hosts, glusterfs has failed. For some reason, it turns inactive state even if I have setup systemctl enable glusterd. Before this command it was just inactive. After this command, it will say "failed (inactive). There is still a way to get glusterfs working. I have to give command systemctl start glusterd manually and everything starts working. Why do I have to give manual commands to start glusterfs? I have used this for CentOS before and never had this problem before. Node installer is that much different from the CentOS core? 3. Epel As I said that I have used CentOS before, I would like to able to install some packets from repo. But even if I install epel-release, it won't find packets such as nano or htop. I have read about how to add epel-release to ovirt node from here: https://www.ovirt.org/release/4.1.1/#epel I have tested even manually edit repolist, but it will fail to find normal epel packets. I have setup additional exclude=collectd* as guided in the link above. This doesn't make any difference. All being said I am able to install manually packets which are downloaded with other CentOS machine and transferred with scp to ovirt node. Still, this once again needs a lot of manual input and is just a workaround for the bug. 4. Engine startup When I try to start the engine when glusterfs is up, it will say vm doesn't exist, starting up. Still, it won't startup automatically. I have to give several times command hosted-engine --vm-start. I wait for about 5minutes until I give it next time. This will take usually about 30minutes and then randomly. Completely randomly after one of the times, I give this command engine shoots up and is up in 1minute. This has happened every time I boot up. And the times that I have to give a command to start the engine, has been changing. At best it's been 3rd time at worst it has been 7th time. Calculating from there it might take from 15minutes to 35minutes to get the engine up.Nevertheless, it will eventually come up every time. If there is a way to get it up on the first try or even better, automatically up, it would be great. 5. Activate storage Once the engine is up, there has been a problem with storage. When I go to storage tab, it will show all sources red. Even if I wait for 15~20minutes, it won't get storage green itself. I have to go and press active button from main data storage. Then it will get main storage up in 2~3munutes.Sometimes it fails it once, but will definitely get main data storage up on the seconds try. And then magically at the same time all other storages instantly go green. Main storage is glusterfs and I have 3 NFS storages as well. This is only a problem when starting up and once storages are on green they stay green. Still annoying that it cannot get it done by itself. 6.Template locked I try to create a template from existing VM and it resulted in original VM going into locked state and template being locked. I have read that some other people had a similar problem and they were suggested to restart engine to see if it solves it. For me it has been now a week and several restarts of engine and hosts, but there is still one VM locked and template locked as well. This is not a big problem, but still a problem. Everything is grey and cannot delete this bugged VM or template. 7. unable to use GPU I have been trying to do GPU passthrough with my VM. First, there was a problem with qemu cmd line, but once I figure out a way to get commands, it maybe is working(?). Log shows up fine, but it still doesn't give functionality I¨m looking for. As I mentioned in the other email that I have found this: https://www.mail-archive.com/users@ovirt.org/msg40422.html . It will give right syntax in log, but still, won't fix error 43 with nvidia drivers. If anybody got this working or has ideas how to do it, would really like to know how it's done properly. I have also tested with AMD graphics cards such as vega, but as soon as drivers have installed, I will get a black screen. Even if I restart VM or hosts or both. I will only see black screen and unable to use VM at all. I might be able to live with the other six things listed above, but this one is a bit of a problem for me. My use of VMs will eventually need graphical performance and therefore I will have to get this working or find an alternative to ovirt..I have found several things that I really like in ovirt and would prefer to use it.

VM remote noVNC console
by Alex K 06 Oct '17

06 Oct '17

Hi all, I am trying to get the VM console of a VM through SSH socks proxy. This is a scenario I will frequently face, as the ovirt cluster will be available only though a remote SSH tunnel. I am trying several console options without success. With SPICE or VNC I get issue with virt-viewer saying "Unable to connect to libvirt with URI [none]' With noVNC I get a separate tab on browser where it is stuck showing "loading". Has anyone success with this kind of remote console access? Thanx, Alex

LVM structure

Hello, I'm still coping with my qemu image corruption, and I'm following some Redhat guidelines that explains the way to go : - Start the VM - Identify the host - On this host, run the ps command to identify the disk image location : # ps ax|grep qemu-kvm|grep vm_name - Look for "-drive file=/rhev/data-center/00000001-0001-0001-0001-00000000033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75" (YMMV) - Resolve this symbolic link # ls -la /rhev/data-center/00000001-0001-0001-0001-00000000033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75 lrwxrwxrwx 1 vdsm kvm 78 3 oct. 2016 /rhev/data-center/00000001-0001-0001-0001-00000000033e/b72773dc-c99c-472a-9548-503c122baa0b/images/91bfb2b4-5194-4ab3-90c8-3c172959f712/e7174214-3c2b-4353-98fd-2e504de72c75 -> /dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75 - Shutdown the VM - On the SPM, activate the logical volume : # lvchange -ay /dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75 - Verify the state of the qemu image : # qemu-img check /dev/b72773dc-c99c-472a-9548-503c122baa0b/e7174214-3c2b-4353-98fd-2e504de72c75 - If needed, attempt a repair : # qemu-img check -r all /dev/... - In any case, deactivate the LV : # lvchange -an /dev/... I followed this steps tens of times, and finding the LV and activating it was obvious and successful. Since yesterday, I'm finding some VMs one which these steps are not working : I can identify the symbolic link, but the SPM neither the host are able to find the LV device, thus can not LV-activate it : # lvchange -ay /dev/de2fdaa0-6e09-4dd2-beeb-1812318eb893/ce13d349-151e-4631-b600-c42b82106a8d Failed to find logical volume "de2fdaa0-6e09-4dd2-beeb-1812318eb893/ce13d349-151e-4631-b600-c42b82106a8d" Either I need two more coffees, either I may be missing a step or something to check. Looking at the SPM /dev/disk/* structure, it looks like very sound (I can see my three storage domains dm-name-* series of links). As the VM can nicely be ran and stopped, does the host activates something more before being launched? -- Nicolas ECARNOT

Hi, I've done all the recommendations in this thread, and I'm still getting the "Paused by System" message just after the transfer starts. Honestly I don't know were else to look at, cause I don't find any log entry or packet capture that give me a hint about what is happening. I'll appreciate any help! Thank you in advance!

I tried a qcow2 disck configured as 40Gb but containing about 1.6Gb of data. I'm going to connect it to a VM and see if all is ok also from a contents point of view.

--=_d5a03c9f-d720-4690-b3f7-196f2e084694 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 7bit Hi, I just installed a hosted engine based four nodes cluster to glustered storage. It seems to working fine, but I have some question about it. - I would like to make an own cluster and datacenter. Is it possible to remove a host and re-add to an another cluster while it is running the hosted engine? - Is it possible to remove default datacenter without any problems? - I have a productive ovirt cluter that is based on 3.5 series. It is using a shared nfs storage. Is it possible to migrate VMs from 3.5 to 4.1 with detach shared storage from the old cluster and attach it to the new cluster? - If yes what will happend with the VM properies? For example mac addresses, limits, etc. Those will be migrated or not?

Guess no one wants to stick around late on a Friday night. :-D I'm an ovirt newb here. I've been going through the docs setting up 4.1 on Scientific Linux 7.4. For the most part everything is going well once I learn how to do it. I'm, however, stuck on power management. I have multiple networks: 192.168.1.x is my BMC/ilo network. The security team wants as few entry points into this as possible and wants as much segregation as possible. 192.168.2.x is my "management" access network. For my other machines on this network this means admin-SSH/rsyslog/SaltStack configuration management/ect. 192.168.3.x is my high speed network where my NFS storage sits and applications that need the bandwidth do their thing. 10.10.86.x is my "public" access All networks are configured on the Host network settings. Mostly confident I got it right...at least each network/IP matches the right interface. ;-) Right now I only have the engine server and one hyper-visor. On either host I can ssh into the command line and run fence_ipmilan -a 192.168.1.x -l USER -p PASS -o status -v -P" it works, all is good. However, when I try to add it in the ovirt interface I get an error. :-/ Edit Host -> Power Management: Address: 192.168.1.14 User Name: root Password: SorryCantTellYou Type: ipmilan Options: <blank> Test Test failed: Failed to run fence status-check on host '192.168.2.14'. No other host was available to serve as proxy for the operation. Yes, same host because I only have one right now. :-) Any help or guidance would be much appreciated. In the meantime I'm going back to the docs to poke at a few other things I need to figure out. :-) Thanks! ~Stack~ --QtNjKESroum0Gs4B16RTXPJnq400V1QDU-- --OnEhT75wdmSi56KelkEfSHNlc4EOmbWar Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAEBCAAGBQJZzqxCAAoJELkej+ysXJPmkn8P/i7sx6DP5aSOejTEvOzq45jc uTYNnoAqniDK/do47z2ojjB0+Oa6czExR7IqyzAzz9+pFEMZlRttxVwQ0XyEj+4t Fw44htR1PhU+YnNQm4fgEo04P7X72qEzdgeMgA/vVVp6chpw0tSG5/bLosrX/yJC NsUF4X0yhnfsCtLZ9Tw78S392OqIQ1iyx12Brmxtip0c97JenMXxXXrxPoUHDFcR T+mqVf7jnC+VxpRj0x5qU+JAOr05oje9coAgbDE6MhWaL6sjClEwhsi5VOU47he9 JcBjKbye4bRHIlzkgpg01Ge0m5fQ4FclJl9wnV4V5vX1Rkuol61wiPQ6SXd/CPy2 PiVsbvX3WloealAupANhaaYG93QPpQsmrw/6Ew/Finlsz6CNfg2VZHbzBGc79QV6 trLMhu+fw7Hsi/lmiU9Rkkmi8OOSgtapMkA283ft1wnBr7gYTyPZwQsp2chO66X5 QZvrRC64nBv9QcVswawWruWSIsETWNNRg7NltEiy8CKBDUsaJ4vJftXzEuHe++ML 2tgOaVRK9nikf6C5OlGPf2TVTVuBRyXGQTVQhGmPVx40499B5sUaen3+dyDHy8QW qLWi6iPiN0YGZkzh/inl/jT4aowQlZEZTfT3KpnH5tyZQ018rcJBQnKFBiTwi5aM /KzRHvKBIvKpjiIREQ7V =kxQZ -----END PGP SIGNATURE----- --OnEhT75wdmSi56KelkEfSHNlc4EOmbWar--

libvirt: XML-RPC error : authentication failed: Failed to start SASL
by Ozan Uzun 02 Oct '17

02 Oct '17

Hello, Today I updated my ovirt engine v3.5 and all my hosts on one datacenter (centos 7.4 ones). and suddenly my vdsm and vdsm-network services stopped working. btw: My other DC is centos 6 based (managed from the same ovirt engine), everything works just fine there. vdsm fails dependent on vdsm-network service, with lots of RPC error. I tried to configure vdsm-tool configure --force, deleted everything (vdsm-libvirt), reinstalled. Could not make it work.

Currenty everything is down. I am ok to install a new ovirt engine if somehow I can restore my virtual servers. I can also split centos 6 and centos 7 ovirt engine's.

iSCSI VLAN host connections - bond or multipath & IPv6
by Ben Bradley 01 Oct '17

01 Oct '17

Hi All I'm looking to add a new host to my oVirt lab installation. I'm going to share out some LVs from a separate box over iSCSI and will hook the new host up to that. I have 2 NICs on the storage host and 2 NICs on the new Ovirt host to dedicate to the iSCSI traffic. I also have 2 separate switches so I'm looking for redundancy here. Both iSCSI host and oVirt host plugged into both switches. If this was non-iSCSI traffic and without oVirt I would create bonded interfaces in active-backup mode and layer the VLANs on top of that. But for iSCSI traffic without oVirt involved I wouldn't bother with a bond and just use multipath. From scanning the oVirt docs it looks like there is an option to have oVirt configure iSCSI multipathing. So what's the best/most-supported option for oVirt? Manually create active-backup bonds so oVirt just sees a single storage link between host and storage? Or leave them as separate interfaces on each side and use oVirt's multipath/bonding? Also I quite like the idea of using IPv6 for the iSCSI VLAN, purely down to the fact I could use link-local addressing and not have to worry about setting up static IPv4 addresses or DHCP. Is IPv6 iSCSI supported by oVirt? Thanks, Ben
