Hi, when I add a disk to a debian 9 VM the VM cannot boot anymore. The VM is stating that /dev/sda1 cannot be found anymore. When I remove the added disk everything works as before. Could someone please give me a hint what went wrong ? The hypervisor host is a Centos 7.5 system. Matze

About Windows guest agent
by jingjie.jiang＠oracle.com 20 Nov '18

20 Nov '18

Hi, I am new in oVirt and I'd like to get the clarification about the packages which support the function of Window guest agent from 4.2 release and how to build it. I looked through the document from ovirt.org, such as https://www.ovirt.org/documentation/internal/guest-agent/guest-agent-for-wi… It mentioned: "With the release of oVirt 3.5 we have introduced the oVirt WGT (Windows Guest Tools). The oVirt WGT provides an ISO with all the tools and drivers one needs to install on a Windows VM, with an easy to use installer to install it all in one step. So manual compilation and installation of oVirt Guest Agent is no longer necessary. The oVirt WGT ISO is included in ovirt-guest-tools-iso-3.5-7.noarch.rpm package." Now, ovirt-guest-tools-iso is up to 4.2.4. I found the src rpm from https://resources.ovirt.org/pub/ovirt-4.2/rpm/el7/SRPMS/ovirt-guest-tools-i…, but I could not find ovirt-guest-tools-iso from github, only found ovirt-wgt. After clone the ovirt-wgt, I got the SPICE-tools-0.141.iso built. My question is : 1. Is ovirt-wgt used for Windows guest? 2. If so, how can I build ovirt-guest-tools-iso package or ovirt-tools-setup.iso Thanks, Jingjie

Call for translators: Russian and Czech
by Sandro Bonazzola 20 Nov '18

20 Nov '18

Hi, one of the beta release criteria is that supported languages have translations at least at 70% of completion. According to zanata[1] we currently have Chinese (Simplified, China) (zh-Hans-CN): 95.1% Czech (cs): 33.97% French (fr) 95.1% German (de) 95.1% Italian (it) 85.84% Japanese (ja): 95.1% Korean (ko) 95.1% Portuguese (Brazil) (pt-BR): 95.1% Russian (ru): 25.17% Spanish (es): 95.1% So, right now Czech and Russian are not meeting release criteria for beta release and are candidate to be disabled in 4.3 unless translators pushes the missing parts.

[ovrit-users] Anyone with Fiber Channel oVirt Storage Experience?
by Jacob Green 20 Nov '18

20 Nov '18

I just have a few simple questions, have you migrated a fiber channel storage domain from one ovirt environment to another? And how did it go, did it just work aside from having to import all the vms and configure their settings was it any more difficult than that? We want to migrate our fiber channel storage with VM's intact from an oVirt 4.1 environment to a brand new oVirt 4.2 environment. We are using fiber channel via An HP MSA. I do not for see any issues, but since we have never done it before, and we do not have spare Fiber Channel storage to test with, we are just unsure of what the behavior should be. So just wanted to get some opinions or basic guidance, is there anything we should watch out for and does it "just work". -- Jacob Green Systems Admin 713-300-5690

External VMs automatically deleted when powered down
by andyg1001＠hotmail.co.uk 20 Nov '18

20 Nov '18

Hi, I have a pressing problem with oVirt, which is sadly languishing as a bug report (#1610917), so I thought I would also raise it here in case anyone else has experience of this and can suggest a workaround or, better yet, a solution to my problem :o) Simply put, the problem is this. I have oVirt 4.2.7 installed on a Cent-OS 7.5 server. It is also necessary, due to various factors, to run what oVirt terms "external VMs" on this server, i.e. ones not managed by oVirt but managed separately, e.g. via virt-manager or virsh. The problem is that once these VMs are shut down (e.g. within the VM or by a command from virt-manager), they are automatically deleted by oVirt some 15 seconds later. The bug report noted above has more details, but these VMs are not created as temporary VMs, and when running the older oVirt 4.1.x or 3.8.x versions, this didn't happen. Looking through the oVirt and libvirt logs, it is really clear that oVirt is responsible for deleting these VMs, so I can rule out any other nefarious agent! Does anyone know of a way of preventing oVirt from deleting external VMs, like a special config option or something? Or does anyone know how to mark a VM as "protected from deletion"? I know oVirt VMs have an option for "delete protection", but oVirt gives the error "Cannot edit VM. This VM is not managed by the engine." if you try to enable it on an external VM. Many thanks, Andy

Who are field-service technicians
by sirishanaginip92＠gmail.com 19 Nov '18

19 Nov '18

Those engineers who work on fields and provide on field service are termed as field technicians. For example, consider 3 SWAN deployments. To complete network deployment, telecom engineers should visit the field and as an initial step, they should perform a site survey followed by deployment. The entire process mentioned needs field service, where their physical presence is required, Hence the need for field service technicians is been increased day by day. Here is the useful URL, that helps in finding the telecom freelancers. https://www.fieldengineer.com/

VM stuck in paused mode with Cluster Compatibility Version 3.6 on 4.2 cluster
by Marco Lorenzo Crociani 19 Nov '18

19 Nov '18

Hi, we upgraded ovirt from version 4.1 to 4.2.6. Rebooted all vms. We missed two vms that were at Cluster Compatibility Version 3.6. There was a gluster/network IO problem and vms got paused. We were able to recover all the other vms from the paused state but we have two vms that won't run because: "Cannot run VM. The Custom Compatibility Version of VM VM_NAME (3.6) is not supported in Data Center compatibility version 4.1." Can we force the CCV of the paused vm to 4.1? Regards, -- Marco Crociani

troubleshooting node upgrade failures
by Jayme 19 Nov '18

19 Nov '18

I have a very standard three node HCI setup running the latest version of oVirt 4.2. I've been having some problems updating hosts, the last update that was released a few weeks ago would produce installfailed when updating hosts. I was able to resolve this by rebooting the host first then performing the update. I eventually got all three hosts updated. Fast forward to this week, a new update is available. I've updated engine successfully but first host, I put in to maintenance then updated and the install is failing. I've rebooted it twice and attempted update again but no go this time. What logs should I be looking at to determine what is causing the node update failures?

How to do per-datacenter/cluster permissions?
by nyhagen＠sedsystems.ca 19 Nov '18

19 Nov '18

Hello! I'm evaluating oVirt for our company, and one thing we need to verify is that users only have access to virtual machines/clusters that they should have access to. I have the users set up from LDAP, and I added the UserRole to them, however it seems like they, by default, have access to every VM available. How do I go about limiting what VMs they have access to? I'd assume I'd have to limit access on a datacenter or cluster level, but I can't seem to find any documentation as to how to do this.

Error start VM with "XML: Multiple 'scsi' controllers with index '0' " - how to workaround?
by Mike Lykov 19 Nov '18

19 Nov '18

Hi all. I'm testing oVirt (it's new to me also) and create some VM with nearly-all-default parameters. (ovirt 4.2.7, with last updates) I create one disk for VM (via webui) : General -> create -> new image with default interface virtio-scsi (boot, 50 Gb size) resource allocation - virtio-scsi enabled by default IO threads enabled by default I run it with cdrom+iso for install centos. When i try to reboot it this VM can start or not can start with error (one time start, next reboot - not start, sometimes after it start...) [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ForkJoinPool-1-worker-3) [] EVENT_ID: VM_DOWN_ERROR(119), VM test_rh1 is down with error. Exit message: Ошибка XML: Обнаружено нескол ько контроллеров «scsi» с индексом «0». (by the way , why errors are localised? it means "Multiple 'scsi' controllers with index '0'" In engine log here is a config xml dump: <controller type="scsi" index="0"> <address bus="0x00" domain="0x0000" function="0x0" slot="0x05" type="pci"/> </controller> <controller type="scsi" model="virtio-scsi" index="0"> <driver iothread="1"/> <alias name="ua-8d89c0be-523d-4e8f-8968-3658adcd6748"/> </controller> It is really contain two controllers: <controller type="scsi" index="0"> <controller type="scsi" model="virtio-scsi" index="0"> But I do NOT add two this controllers by hand! And sometimes it can start! (without configuration change) So there is a Question: How to workaround this and start the VM? In "vm devices" I have two controllers: virtio-scsi {ioThreadId=1} scsi {type=pci, slot=0x05, bus=0x00, domain=0x0000, function=0x0 {index=0} But all checkboxes are greyed bug like in this list post: https://lists.ovirt.org/pipermail/users/2018-February/086860.html There is a "CLOSED" bugs about this https://bugzilla.redhat.com/show_bug.cgi?id=1543833#c9 https://bugzilla.redhat.com/show_bug.cgi?id=1563769 https://bugzilla.redhat.com/show_bug.cgi?id=1535961 -- Mike

GlusterFS LibgfApiSupported and High Availability
by Shawn Weeks 19 Nov '18

19 Nov '18

Currently when LibgfApiSupported is enabled it looks like the startup command for the VM has the Gluster hostname always set to the same host. How does that work if that host is down? In my case GlusterFS has 3x replication and distribution enabled but if the first host is down the VMs don't work. I'm on GlusterFS 4.1 and oVirt 4.2 latest. Thanks Shawn

Can't install windows guest
by bardos.matyas＠techcentral.hu 18 Nov '18

18 Nov '18

Dear list, I am new in ovirt, and I have a problem, which I can’t solve with google. I am not able to install windows guests, because they can’t find they disk. I have already many linux guests running, so generally everything is working fine. I try with virtio-scsi disks. What I already tried: - While the installation process I changed the disk to the virtio driver disk (downloaded from fedora project), I try to load scsi drivers, and windows still can’t find the disk - I tried with virtio floppy (run once) but the floppy is not visible in windows select menu - I added the drivers to windows installer wim, but disks still not visible - I tried to add ide drive, but it is not visible either (I have disabled virtio scsi under resource allocation too, without luck) - tried windows 7 and 2016 My nodes are: oVirt Node 4.2.1.1 I use local disks but via nfs, so i share the local disk via nfs. Do you have any idea what could I try. Any clue are welcome, because I’m stuck… Thank you in advance! Regards!

Unable to import engine
by Alex K 18 Nov '18

18 Nov '18

Hi all, I had a setup with ovirt 4.2.0 which at some point the engine stopped responding, due to some split brain issues. Since was not able to resolve the split brain, I proceeded to redeploy the engine.

Script for backing up VMs
by mail＠karloluiten.nl 18 Nov '18

18 Nov '18

Hi All, I love oVirt, have been running it for some weeks now. I have read the wiki page on backups, and have set up an engine backup. The backing up of VMs is where it gets more tricky. There must be more people already doing this, but I just would like some script that takes my vm name as an argument, and saves a backup (snapshot) of the vm. If someone could help me, that would be awesome. If there is an even easier way to do it (copying files on the FS itself?), that could be even better. I know this question has been asked multiple times over the last years, but I can not find an actual, working, documented way of doing this. Thanks so much, and thanks for creating/maintaining/fixing/building oVirt! Karlo

Increasing an Existing iSCSI Storage Domain
by Brian Wilson 17 Nov '18

17 Nov '18

My Question is not so much in how to do this as i have been able to take an existing Storage domain and increase its size with adding another LUN. My Question is how will a failure of one of the LUNs be handled by the engine and how will it effect the VMs running on it. Let me setup an example to better illustrate. Ovirt Node has ISCSI storage domain comprised of 1 Lun from 1 ISCSI based SAN and 2 LUNs from another. So a total of 3 Luns making up the one storage domain. Now there is an issue with the Storage array providing the single lun. What happens? How do you know what VMs are running on each extent? TIA Brian

Hyperconverged Ovirt + ZFS
by Thomas Simmons 17 Nov '18

17 Nov '18

Hello All, I recently took a new job in a RedHat shop and I'd like to move all of my homelab systems to RedHat upstream products to better align with what I manage at work. I had a "custom" (aka - hacked together) 3-node Hyperconverged XenServer cluster and would like to get this moved over to Ovirt (I'm currently testing with 4.2.7). Unfortunately, my storage is limited to software RAID with a 128GB SSD for cache. If at all possible, I would prefer to use ZFS (RAIDZ+ZIL+L2ARC) instead of MD RAID + lvmcache, however I'm not able to get this working and I'm not sure why. My ZFS and Gluster configuration is working - at least where I can manually mount all of my gluster volumes from all of my nodes, however, hosted-engine --deploy fails. I understand this isn't an out of the box configuration for Ovirt, however I see no reason why this shouldn't work. I would think this would be no different than using any other Gluster volume for the engine datastore, Am I missing something that would prevent this from working? [ INFO ] TASK [Add glusterfs storage domain] [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Storage Domain target is unsupported]". HTTP response code is 400.

oVirt monitoring
by b.yuri8＠gmail.com 16 Nov '18

16 Nov '18

Hello, I'm trying to do some performance monitoring on our oVirt and want to ask if someone has any experience with it? Currently I'm trying Red Hat Virutalization tool which has REST API, where you can get statistics per host, vm, disk and nic. Problem is that you cannot get any historical data via rest api (at least I didn't find any way to do it) and almost all metrics are gauge values over some interval (couldn't find it documentation, but it looks like they are updated every 15 s). I surely don't want to query whole environment every 15 seconds and missing some values is also not an option since I could miss some spikes in performance. Any help is appreciated! George

OVS and Ovirt integration questions
by 0pk0de＠riseup.net 16 Nov '18

16 Nov '18

Hello, After having integrated OVS with Ovirt and enabled it as default network provider I am facing the following issues. I can see with "ovs-vsctl show" that the virtual switch / bridge called "br-int" is created. I can see interfaces being added / removed to it as I start / stop VMs. [root@******* ~]# ovs-vsctl show 78e883f9-f074-4292-afce-bb829ded856b Bridge br-int fail_mode: secure Port "vnet6" Interface "vnet6" Port br-int Interface br-int type: internal Port "vnet4" Interface "vnet4" ovs_version: "2.9.0" Now I for example want to create a new interface as shown: ip tuntap add mode tap sniff0 ovs-vsctl add-port br-int sniff0 -- --id=@p get port sniff0 -- --id=@m create mirror name=m0 select-all=true output-port=@p -- set bridge br-int mirrors=@m fae36943-2ca7-4914-9679-0b881cd062d8 Its created, but how do I assign this sniffing interface to a ovirt VM? also, how can I create sniffing ports listening only on a subset of interfaces if they get dynamically created / removed? vnet6 points to host A now, but after shutting it down starting a few other VMs it will point to host B... How do I control to what vm the vnetX nic gets assigned?

Foreman integration / Network integration (storage)
by jeanbaptiste＠nfrance.com 16 Nov '18

16 Nov '18

Hello everybody, I use oVirt with Foreman to bare metal provision hypervisor. On foreman side, I use excellent Discovery plugin firstly. Afterthat I configure a "bond0" lagg on Network host tab. Into this bond0, I create some "virtual interface" (bond0.15 for example) with a static IP assignation via integrated Foreman IPAM. All is pretty cool, but after oVirt installation is done, I'm "forced" via postinstall to apply: Add "NM_Controlled=no" to all my bond0.* interfaces. Afterthat on oVirt , Host, "Setup Host Network", I'm able to move my network to the host and have automatically the IP address "configured" since read from the ifcfg file. This method seem to work but only in "one time mode". There is no real link between oVirt and Foreman for IP assignement. Do you use anothers way to provision bare metal hypervisor and have automatic IP assignement (for storage network for ex) between these two excellent tools ? thanks !

using vlan-tagged nic for ovirtmgmt

Engine login fails after previously working.
by Jeremy Tourville 16 Nov '18

16 Nov '18

I recently completed setup for 389 DS and ovirt-engine-extension-aaa-ldap-setup. I was able to complete the script run without errors and could perform both login and search functions without issue. Initially after setup I was able to login. After getting all this to work I had rebooted the 389 DS server. I tried to login as the super user I created earlier. I am getting the message "Unable to login. Verify your login information or contact the system administrator." This issue only seemed to happen after the reboot, prior to that it had been working. Any thoughts on troubleshooting? Thanks in advance.

VM import using wrong/slower interface. help/question.
by Jacob Green 15 Nov '18

15 Nov '18

Currently I have a host that has multiple network connections. 1 bonded 20Gigabit connect and a couple of 1 gig Ethernet connections. Then my export storage domain is on a storage device on a vlan we can call vlan B. Today I was exporting a VM from one environment to another, and after I reattached the export domain and started importing I noticed an even message for one of my hosts, it looked like the following. "Host A has network interface which exceeded the defined threshhold [95%] (eno3: transmit rate [8%], receive rate [98%])" So when I take a look at that hosts interfaces in the OVIRTENGINE gui I can confirm that it is exceeding 900Mbits on that interface. The problem/question is this. I have the migration network set as well as the ovirtmgmt network on the 20Gigabit interface. The only network profile attached to ENO 3 is VLAN-B and only VM traffic on that profile. So why is it using that eno3 interface instead of the ovirtmgmt interface on the 20Gigabit interface to import the VM? So I do have at least one theory, the storage solution is also on VLAN B the same VLAN that eno3 rides on, but I am of the understanding that Ovirt should be instructing the host to use the migration network, which in my case is also my ovirtmgmt network on the 20Gigabit interface. It matters because my storage is also on a 20Gigabit bond and these imports would be a lot faster if it was using the correct network to the host to import the VM. I hope my question is clear enough, I would provide screenshots but the ovirt-users mailing lists scrubs those. Basically can I instruct or force ovirt to import VMs over my 20Gigabit interface instead of the slower 1Gig interface that is hooked up. Thank you. -- Jacob Green Systems Admin

How to force a QoS IO limit update to all disks
by Florian Schmid 15 Nov '18

15 Nov '18

Hi, oVirt version: 4.2.5.1 I have a strange problem with IO limiting. I have a storage domain for our dev environment and I have set the default Disk Profile to a QoS rule with IO limit enabled. This rule is working so far, but when I change the QoS rule of this default Disk Profile to a different IO limit, all the disks have still the old limit active. Only when I edit the disk and click OK without changing anything, I see also in Events, that the new IO limit is set. This behavior would cause me a lot of work, because we have several 100s of disks and I can't edit all, only to have new QoS active. Is there another way to do this bulk change of disk IO limit? What data do you need to have a look on? EDIT: I saw now, that the QoS policy is automated updated on some VMs and there only on some disks, but not on all. Is there a rate limit active or so?

Ovirt and Foreman integration failure to provision
by 0pk0de＠riseup.net 15 Nov '18

15 Nov '18

Hello, I am trying to integrate ovirt and foreman, foreman is able to create VMs but fails to provision them correctly (image/template based). The IP address does not get set to the correct one, cloud-init doesnt run either since the password is not correct after booting. My questions are the following: 1. how does the normal provisioning setup looks like (using image/template)? I assumed it would just provision it depending on my puppet classes after booting, is this incorrect? 2. What does foreman *need* from ovirt? does it need a template that for example already has puppet installed? I assumed this was not the case... 3. How is it possible to initially "seed" the vm with the puppet master details when not using cloud-init (which seems optional), what magic can make this happen behind the scenes? is it something like libguestfs? Can I just use a cloud glance image like "centos 7 generic cloud v1805" and import that as a template and then create a host on foreman using this template? and then it should provision it?

Single Node oVirt and Gluster Hyperconverged
by Jeremy Tourville 15 Nov '18

15 Nov '18

I have a question about this specific prerequisite- * You must have at least 2 interfaces on the host, so that the frontend and backend traffic can be separated out. Having only one network will cause the engine monitoring, client traffic, gluster I/O traffic to all run together and interfere each other. To segregate the backend network, the gluster cluster is formed using the backend network addresses, and the nodes are added to the engine using the frontend network address. >>>You must have at least 2 interfaces on the host, so that the frontend and backend traffic can be separated out.>>>This part is very clear to me. You need at least 2 NICs. >>>Having only one network will cause the engine monitoring, client traffic, gluster I/O traffic to all run together and interfere each other. To segregate the backend network, the gluster cluster is formed using the backend network addresses, and the nodes are added to the engine using the frontend network address.>>> Ok, so you definitely need two IPs. What is not clear to me is, do you need to have the IPs in different subnets or can they be in the same subnet? For reference, I was able to set this up with two IPs in the same subnet and it does seem to work. However, I have noted some slowness issues while connecting storage domains during startup and frequently get messages about needing to restart the HA agent. Usually it seems after I try to restart services I can get the system to recognize the engine storage domain and start the engine. I wonder if my problem is the fact that both my front and backend IPs are in the same subnet? Thanks for your advice.

Re: ovirt-engine-extension-aaa-ldap-setup failed
by Jeremy Tourville 15 Nov '18

15 Nov '18

The backend is 389 DS, no this is not Govt related. This will be used as a training platform for my local ISSA chapter. This is a new 389 DS server. I followed the instructions at https://www.unixmen.com/install-and-configure-ldap-server-in-centos-7/ The server is "stock" with the exceptions of the settings for startTLS and adding certificates, etc (basically, whatever is needed to integrate with the Ovirt Engine.) I am using my Admin account to perform the bind. What I don't understand is why everything else in the aaa setup script works except the login sequence. It would seem like my certificates are correct, correct use of the admin DN, etc. The funny part is I can login to the server using the admin account and password yet the same admin account and password fail when using the aaa setup script. But, that is why I am using the expert knowledge on the list! Maybe I have overlooked a simple prerequisite setting needed for setup somewhere? I'll wait for someone to chime in on possible reasons to get this message: SEVERE Authn.Result code is: CREDENTIALS_INVALID [ ERROR ] Login sequence failed ______________________________________________ Users mailing list -- users(a)ovirt.org<mailto:users@ovirt.org> To unsubscribe send an email to users-leave(a)ovirt.org<mailto:users-leave@ovirt.org> Privacy Statement: https://www.ovirt.org/site/privacy-policy/ oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/TGT7ASCWSUTU6…

Separating VM network
by d.gengenbach＠patagona.de 14 Nov '18

14 Nov '18

We would like to separate our VM traffic completely from our host/storage network. As far as I can see, there is no definitive guide to achieve this by using VLANs/separate VM networks/subnetting. In our current setup: - the storage traffic happens in a separate VLAN (configured directly on the switch) on separate NICs on both hosts/storages in the 192.168.179.0/24 subnet - all other infrastructure (oVirt hosts, gateway, DHCP, DNS, VM thinclients, switches, ...) are in the 192.168.178.0/24 subnet We now want to separate the oVirt hosts/engine completely from the other infrastructure, eg. the VMs and thinclients. I am not experienced in networking and would be very thankful for all hints/tipps! Thanks in advance, David

Migrate datacenter with hosts and VM managed from engine no1 to engine no2
by Punaatua PK 14 Nov '18

14 Nov '18

Hello, we have the current setup. => 1 datacenter on site A with 1 cluster which is compose of 3 hosts and a self-hosted engine => 1 datacenter on site B (let's call this TATA) with 1 cluster compose of 3 hosts which is using glusterfs. This datacenter is managed by the self-hosted engine on site A We want to create on site B another datacenter with 1 cluster and another self-hosted engine then disengage datacenter TATA from self-hosted engine on site A. after that, we want to import all the ressource on the self-hosted engine on site B Is it possible to do this without loosing VM on glusterfs ? Off course VM will be shutdown during the operation. I mean, when a host is added on a new datacenter, ovirt will install package if necessary. Is there any way that ovirt manager erase actual configuration ? Is it safe to do this operation ?

Windows VM always growing
by Thomas Fecke 14 Nov '18

14 Nov '18

Hey Guys, we use, for our Windows VMs, "thin Provision". The Problem: the Disk always grow but if I delete Files in Windows the actual Disk size stays the same. Any way to get the "real" Windows Size back again? Some VMs got an Actual Size from about 100 GB - but Windows just got 25 GB Thanks in advanced Thomas

Engine trying to activate already activated hosts, causing serious instability...
by Jason P. Thomas 14 Nov '18

14 Nov '18

I've got a 4 node cluster running oVirt 4.2.7. 3 hosts are hyperconverged with glusterfs. Engine is running on one of the gluster volumes. Since yesterday, the cluster is completely unstable and will not reliably run VMs including the Engine. A notification will pop up in the WebUI stating "Finished invoking activate on host ovirt1" while the task list indicates "Activating host ovirt1". When this task ultimately fails, the node in question goes NonOperational. All our VMs have been down since 3pm yesterday, so help is greatly appreciated. Sincerely, Jason
