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 ?

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.

[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.

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!

ovirt-hosted-engine state transition messages
by Jim Kusznir 23 Jul '17

23 Jul '17

Hello: I find that I often get random-seeming messages. A lot of them mention "ReintializeFSM", but I also get engine down, engine start, etc. messages. All the time, nothing appears to be happening on the cluster, and I rarely can find anything wrong or any trigger/cause. Is this normal? What causes this (beyond obvious hardware issues / hosts rebooting)? Most of the time when I get these, my cluster is going along smoothly, and nothing (not even administrative access) is interrupted. Could ISP issues cause these messages to be generated? Thanks! --Jim

Hello, I'm trying to find a way to clean up the VMs list of my DCs. I think some of my users have created VM they're not using anymore, but it's difficult to sort them out. In some cases, I can shutdown some of them and wait. Is there somewhere stored in the db tables the date of the last VM exctinction? Thank you. -- Nicolas ECARNOT

Cloning VM on NFS Leads to Locked Disks
by Charles Tassell 06 Jul '17

06 Jul '17

Hi Everyone, I'm having some issues with my oVirt 4.1 (fully updated to latest release as of yesterday) cluster. When I clone a VM the disks of both the original and the clone stay in the locked state, and the only way I can resolve it is to go into the database on the engine and run "update images set imagestatus=1 where imagestatus=2;" I'm using NFS4 as a datastore and the disks seem to copy fine (file sizes match and everything), but the locking worries me. To clone the VM I just shut the source VM down and then right click on it and select "Clone" I've attached the full VDSM log from my last attempt, but here is the excerpt of the lines just referencing the two disks (d73206ed-89ba-48a9-82ff-c107c1af60f0 is the original VMs disk and 670a7b20-fecd-45c6-af5c-3c7b98258224 is the clone.) 2017-05-10 11:36:20,120-0300 INFO (jsonrpc/2) [dispatcher] Run and protect: copyImage(sdUUID=u'20423d5e-188c-4e10-9893-588ceb81b354', spUUID=u'00000001-0001-0001-0001-000000000311', vmUUID='', srcImgUUID=u'd73206ed-89ba-48a9-82ff-c107c1af60f0', srcVolUUID=u'bba1813d-9e91-4e37-bed7-40beedda8051', dstImgUUID=u'670a7b20-fecd-45c6-af5c-3c7b98258224', dstVolUUID=u'013d8855-4e49-4984-8266-6a5e9437dff7', description=u'', dstSdUUID=u'20423d5e-188c-4e10-9893-588ceb81b354', volType=8, volFormat=5, preallocate=2, postZero=u'false', force=u'false', discard=False) (logUtils:51) 2017-05-10 11:36:20,152-0300 INFO (jsonrpc/2) [storage.Image] image d73206ed-89ba-48a9-82ff-c107c1af60f0 in domain 20423d5e-188c-4e10-9893-588ceb81b354 has vollist [u'bba1813d-9e91-4e37-bed7-40beedda8051'] (image:319) 2017-05-10 11:36:20,169-0300 INFO (jsonrpc/2) [storage.Image] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 imgUUID=d73206ed-89ba-48a9-82ff-c107c1af60f0 chain=[<storage.fileVolume.FileVolume object at 0x278e450>] (image:249) 2017-05-10 11:36:20,292-0300 INFO (tasks/0) [storage.Image] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 imgUUID=d73206ed-89ba-48a9-82ff-c107c1af60f0 chain=[<storage.fileVolume.FileVolume object at 0x302c6d0>] (image:249) 2017-05-10 11:36:20,295-0300 INFO (tasks/0) [storage.Image] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 vmUUID= srcImgUUID=d73206ed-89ba-48a9-82ff-c107c1af60f0 srcVolUUID=bba1813d-9e91-4e37-bed7-40beedda8051 dstImgUUID=670a7b20-fecd-45c6-af5c-3c7b98258224 dstVolUUID=013d8855-4e49-4984-8266-6a5e9437dff7 dstSdUUID=20423d5e-188c-4e10-9893-588ceb81b354 volType=8 volFormat=RAW preallocate=SPARSE force=False postZero=False discard=False (image:765) 2017-05-10 11:36:20,305-0300 INFO (tasks/0) [storage.Image] copy source 20423d5e-188c-4e10-9893-588ceb81b354:d73206ed-89ba-48a9-82ff-c107c1af60f0:bba1813d-9e91-4e37-bed7-40beedda8051 vol size 41943040 destination 20423d5e-188c-4e10-9893-588ceb81b354:670a7b20-fecd-45c6-af5c-3c7b98258224:013d8855-4e49-4984-8266-6a5e9437dff7 apparentsize 41943040 (image:815) 2017-05-10 11:36:20,306-0300 INFO (tasks/0) [storage.Image] image 670a7b20-fecd-45c6-af5c-3c7b98258224 in domain 20423d5e-188c-4e10-9893-588ceb81b354 has vollist [] (image:319) 2017-05-10 11:36:20,306-0300 INFO (tasks/0) [storage.Image] Create placeholder /rhev/data-center/00000001-0001-0001-0001-000000000311/20423d5e-188c-4e10-9893-588ceb81b354/images/670a7b20-fecd-45c6-af5c-3c7b98258224 for image's volumes (image:149) 2017-05-10 11:36:20,392-0300 INFO (tasks/0) [storage.Volume] Request to create RAW volume /rhev/data-center/00000001-0001-0001-0001-000000000311/20423d5e-188c-4e10-9893-588ceb81b354/images/670a7b20-fecd-45c6-af5c-3c7b98258224/013d8855-4e49-4984-8266-6a5e9437dff7 with size = 20480 sectors (fileVolume:439) 2017-05-10 11:37:58,453-0300 INFO (tasks/0) [storage.VolumeManifest] sdUUID=20423d5e-188c-4e10-9893-588ceb81b354 imgUUID=670a7b20-fecd-45c6-af5c-3c7b98258224 volUUID = 013d8855-4e49-4984-8266-6a5e9437dff7 legality = LEGAL (volume:393)

iSCSI storage domain and multipath when adding node
by Gianluca Cecchi 27 Jun '17

27 Jun '17

Hello, my configuration is what described here: http://lists.ovirt.org/pipermail/users/2017-March/080992.html So I'm using iSCSI multipath and not bonding can anyone reproduce? Initial situation is only one node configured and active with some VMS I go and configure a second node; it tries to activate but networks are not all already mapped and so gies to non operational. I setup all networks and activate the node It happens that: - on the first node where I currently have 2 iSCSI connections and 2multipath lines (with p1p1.100 and p1p2) it is instantiated a new iSCSI SID using interface "default" and in multipath -l output I see now 3 lines - on the newly added node I only see 1 iSCSI SID using interface default My way to solve the situation was to go inside iscsi multipath section do nothing but save the same config brutally on first node iscsiadm -m session -u --> all iscsi sessions are closed after a while I see again the original 2 connections recovered, with correct interface names used - on second node iscsiadm -m session -u --> the only session is cloed nothing happens if I set to maintenance the node and then activate the node --> the 2 correct iscsi sessions are activated... Thanks Gianluca

Info on live snapshot and agent interaction
by Gianluca Cecchi 23 Jun '17

23 Jun '17

Hello, supposing to have a Linux VM with ovirt-guest-agent installed, during a live snapshot operation it should be freeze of filesystems. Where to find confirmation of correct/successful interaction? /var/log/messages or agent log or other kind of files? Are there any limitations on filesystems that support freeze? Is it fsfreeze the command executed at VM OS level or any other low level command? Thanks, Gianluca

Lowering the bar for wiki contribution?
by Roy Golan 21 Jun '17

21 Jun '17

I'm getting the feeling I'm not alone in this, authoring and publishing a wiki page isn't as used to be for long time. I want to suggest a bit lighter workflow: 1. Everyone can merge their page - (it's a wiki) Same as with (public and open) code, no one has the motivation to publish a badly written wiki page under their name. True, it can have an impact, but not as with broken code 2. Use Page-Status marker The author first merges the draft. Its now out there and should be updated as time goes and its status is DRAFT. Maintainers will come later and after review would change the status to PUBLISH. That could be a header in on the page: --- page status: DRAFT/PUBLISH --- Simple I think, and should work.

Hosted Engine Setup with the gluster bricks on the same disk as the OS
by Mike DePaulo 18 Jun '17

18 Jun '17

Hi. I am trying to follow this guide. Is it possible to use part of my OS disk /dev/sda for the bricks? https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluste… I am using oVirt Node 4.1.1.1. I am aware of the manual partitioning requirements. I am guessing I have to create an LV for the OS that does not take up the entire disk during install, manually create a pv like /dev/sda3 afterwards, and then run Hosted Engine Setup and specify /sda3 rather than sdb? Thanks, -Mike

Building oVirt engine on Debian
by Leni Kadali Mutungi 09 Jun '17

09 Jun '17

Ran `make clean install-dev` and the process freezes at: [INFO] weaveinfo Join point 'constructor-execution(void com.google.gwt.dev.jjs.impl.ControlFlowAnalyzer.<init>(com.google.gwt.dev.jjs.ast.JProgram))' in Type 'com.google.gwt.dev.jjs.impl.ControlFlowAnalyzer' (ControlFlowAnalyzer.java:905) advised by after advice from 'org.ovirt.engine.ui.gwtaop.DontPrune' (DontPrune.java) My computer freezes at that point and I have to power it off. I tried doing it in the terminal without the Desktop Environment and I get the same result. The component being built is the UI Common Web. Advice on what to do next is appreciated. -- - Warm regards Leni Kadali Mutungi

This is a multi-part message in MIME format. --------------DC86F700F56181ECDB9F4F15 Content-Transfer-Encoding: 8bit Content-Type: text/plain; charset=utf-8; format=flowed Hi all. I have to servers with ovirt. And to identical virtual machines. Both servers are identical. But on second virtual server not working one network interface. Ping have a problem. I tried to change network driver, but has no effect.

Any ideas what this is: TASK [Run a shell script] ****************************************************** fatal: [ovirt-node1.lab]: FAILED! => {"failed": true, "msg": "The conditional check 'result.rc != 0' failed. The error was: error while evaluating conditional (result.rc != 0): 'dict object' has no attribute 'rc'"} fatal: [ovirt-node3.lab]: FAILED! => {"failed": true, "msg": "The conditional check 'result.rc != 0' failed.

nic order
by Nathanaël Blanchet 07 Jun '17

07 Jun '17

Hi all, I added a new nic on all my vms, but the MAC address pool was too small. So I extended it from 00:1a:4a:22:1f:00 to 00:1a:4a:22:1f:ff => 00:1a:4a:22:1e:00 to 00:1a:4a:22:1f:ff. It was okay but when rebooting some vms, nics are interverted and I couldn't join my vm on ip! I noticed nics were ordered now from the smallest MAC address to the greatest one, so the last plugged nic from the new pool was now the first in the vm, and all nics were moved at the bottom. Is it an expected behaviour? -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Nested KVM for oVirt 4.1.2
by ovirt＠fateknollogee.com 06 Jun '17

06 Jun '17

http://community.redhat.com/blog/2013/08/testing-ovirt-3-3-with-nested-kvm/ I have one CentOS7 host (physical) & 3x oVirt nodes 4.1.2 (these are vm's). I have installed vdsm-hook-nestedvm on the host. Should I install vdsm-hook-macspoof on the 3x node vm's?
