Could not detect Guest Agent on the VM. Note that without a Guest Agent the data on the created snapshot may be inconsistent!

Hi evrybody! First of all sorry for my language. On windows machines despite the installation of oVirt Guest Tools4.2-4.el7 a warning is issued as in Title. My solucion: a) ovirt-engin DB update vdc_options set option_value='ovirt-guest-agent-common,ovirt-guest-agent,oVirtGuestTools' where option_name='AgentAppName'; b) windows VM Change DisplayName registry: Computer\HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows\CurrentVersion\Uninstall\oVirtGuestTools to oVirtGuestTools-4.2-4.el7. Restart OVirt Guest service

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. The steps I followed: 1. upgrade servers (yum update) 2. ran ovirt-hosted-engine-cleanup 3. deployed engine (now 4.2.7) The deploy was successful and was able to add a new data domain. The issue is that at this point I would expect the engine storage domain and VM to be automatically imported, but it is not. At HA agent logs at the server I see: MainThread::INFO::2018-11-17 12:55:51,856::states::444::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine::(consume) Engine vm running on localhost MainThread::WARNING::2018-11-17 12:55:52,145::ovf_store::140::ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore::(scan) Unable to find OVF_STORE MainThread::ERROR::2018-11-17 12:55:52,146::config_ovf::84::ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config.vm::(_get_vm_conf_content_from_ovf_store) Unable to identify the OVF_STORE volume, falling back to initial vm.conf.

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
