ovirt and terraform disk size issue on template creation
by cello86＠gmail.com 22 Jun '23

22 Jun '23

Hi, I tried to create a VM from an OVF template imported on ovirt 4 but the VM has a disk size of 2 GBs and if I tried to attach a different disk this operation gone in timeout. I understand that you have to create the vm and assign disk and nic after the creation but I do not fully understand the templates attachments override option. Can you help me to understand the correct procedure to set the correct space on the new vm? Thanks, Marcello

Hello. web access on ovirt-engine is not working. find information about certificate renewal: hosted-engine --set-maintenance --mode=global !! Cluster is in GLOBAL MAINTENANCE mode !! run engine-setup --offline Renew certificates? (Yes, No) [No]: yes but got an error [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data.

VM migration failed after upgrade to 4.4
by joris dedieu 20 Jun '23

20 Jun '23

Hi list, I'm troubleshooting an issue with live migration on an upgrade context. I have a 4.3 cluster that I try to upgrade in 4.4. The engine is OK in 4.4 and I already have upgraded a single host which had kindly reintegrated the cluster. The host is OK. I can start vms on it and migrate vms from it to other hosts. But, if I try to migrate a vm from a 4.3 host to the 4.4 host, it failed with : * on the host : qemu-kvm: terminating on signal 15 from pid XXXX (<unknown process>) * on the engine : VM 'VM_UUID' was unexpectedly detected as 'Down' on VDS 'HOST_UUID' Does anyone here can help me to find what's goning on ? I will be greate regards Joris

Cannot start VM with vGPU (NVIDIA)
by pawel.osadtschy01＠dhl.com 20 Jun '23

Hi, need a help! may be the problem is very simple, but I've not found solution: -oVirt 4.5.4 on RHEL 8.7 -amd_iommu is on on the Host with Nvidia Card A40 I can see my cards in vGPU Settings for Windows VMs (Windows 10 Pro). Without activation of the vGPU device VM started normally. With one active vGPU card VM cannot start. Error message on the Host: Jun 07 13:39:51 depotlsa8ovh1 kernel: [nvidia-vgpu-vfio] e80ae200-4cea-4213-9e78-ebf0b86a756a: start failed. status: 0x0 Timeout Occured Jun 07 13:39:51 depotlsa8ovh1 libvirtd[3278]: Kann nicht vom Monitor lesen: Die Verbindung wurde vom Kommunikationspartner zurückgesetzt Jun 07 13:39:51 depotlsa8ovh1 libvirtd[3278]: Interner Fehler: qemu unexpectedly closed the monitor: 2023-06-07T11:39:51.494056Z qemu-kvm: -device vfio-pci-nohotplug,id=hostdev0,sysfsdev=/sys/bus/mdev/devices/e80ae200-4cea-4213-9e78-ebf0b86a756a,display=on,ramfb=on,bus=pci.7,addr=0x0: vfio e80ae200-4cea-4213-9e78-ebf0b86a756a: error getting device from group 156: Connection timed out. Verify all devices in group 156 are bound to vfio-<bus> or pci-stub and not already in use. Looks like libvirtd cannot get any device. Is it problem of Nvidia settings on the host or Problem of VM settings? Thank you Paolo

Hello, I'm seeing the same when trying to install nightly on high-end server (Either direct over NFS or gluster cluster). Seems that oVirt deployment fails to change the HE IP address after deployment. I'm thinking about trying other options, such as switching to Oracle (Ugh!) / oVirt 4.4 which seems to be stable and has long term support. - Gilboa On Sun, Jun 11, 2023 at 4:30 PM Angel, Christopher < christopher.angel(a)usask.ca> wrote: > I’ve installed 3 Ovirt Nodes and am trying to set up the hosted engine. > Every time I run it however, it fails at the ‘Waiting for host to be up’ > stage.

Re: Resending with Log: Hosted Engine Deploy Fails at "Waiting for Host to be up"
by Thomas Hoberg 15 Jun '23

I have seen this type of behavior when building a HCI cluster on Atoms. The problem is that at this poing the machine that is generated for the management engine has a machine type that is above what is actually supported in hardware. Since it's not the first VM that is run during the setup process, it's not really intuitive but the libvirt configuration for that prototypical management engine is created by code that assumes to modern a default (I never found the source, but since all development has ceased it won't matter any more). While modern Atoms are actually more like Core CPUs in terms of the instruction set they support, my Goldmont Plus/Gemini Lake Atoms were regarded by KVM as next to a Nehalem CPU and the VM would refuse to start. It's very hard to find in the logs, because it is actually a KVM issue (created by the oVirt ME creation mechanism, of couse). I got out of that fix using removable storage: I had the setup run on an i7-7700k (was a bit faster, too) and then changed the machine type of the management engine (and lowest common denominator for the cluster) to Nehalem before transplanting the SSD back into the Atom. I've gone through that excercise with ovirt 4.3 and again with Oracle's 4.4 variant, which is by far the most stable oVirt/RHEV available right now.

Windows VMs pause ofte when disk images are located on CephFS storage
by change_jeeringly679＠dralias.com 15 Jun '23

15 Jun '23

Hey guys, I have tried to write on the IRC channel, regarding this issue, but I'm no sure if I'm not doing it right or maybe there are not many people watching the #ovirt channel. We have deployed a 6 node oVirt cluster, and have moved roughly 100 VMs on them. We started the cluster with NFS storage, which we were building and testing with our Ceph cluster. The Ceph has been ready for a few months now, and we have tested running oVirt VMs on it using RBD, CephFS and by using the NFS Ganesha server which can be enabled on Ceph. Initially I tested with RBD using the cinderlib functionality in oVirt. This appears to be working fine, and I can live with the fact tha live storage migrations from posix storage are not possible. The biggest hurdle vi encountered are, that the backup APIs in oVirt cannot be used to create a backup and download the backups. This breaks our RHV Veeam backup solution, which we have grown quite fond of. But even my homegrown backup solutions from earlier don't work either, as they use the APIs. For this reason we have now changed to CephFS. It has a different set of problems, as we can only supply 1 monitor when mounting the CephFS storage, making i less robust as it should be. It is also making metadata storage dependent on the MDS. As far as I understand, is data access still connecting to the OSDs where it resides directly. I have multiple MDS containers on the Ceph cluster for loadbalancing and redundancy, but it still feels less tidy than RBD with native Ceph support. The good thing is, that as CephFS is a POSIX filesystem, the backup APIs work and so does Veeam backup. The biggest problems I am struggling with, is the unexplained pausing of exclusively VMs running the Windows Operating system. This is why I didn't notice issues initially, as I have been testing the storage with Linux VMs. The machines pause at a random moment in time with a "Storage Error". I cannot resume the machine, not even using virsh on the host it is running on. The only thing I can do is power it off, and reboot. And in many cases, it then pauses during the boot process. I have been watching the VDSM logs, and couldn't work out why this happens. When I move the disk to plain NFS storage (not on Ceph), this never happens. The result is that most Windows based VMs have not been moved yet to CephFS. I have 0 occurrences of this happening with Linux VMs, of which I have many (I think we have 80 linux VMs vs 20 Windows VMs). The Ceph cluster does not show and problems before, during or after this happening. Is there anyone with experience wih oVirt and Ceph, that can share experiences or help me find the root cause of this problem? I have a couple of things I can progress wih: 1. Move a couple of Windows VMs to RBD, and install a Veeam agent on the servers instead. This is just opening a new can of worms, as it requires some work on the servers each time I add a new server and I also need to make network openings from the server to the backup repos. It is just a little less neat than the RHV Veeam backup solution using the hypervisor. 2. Move a couple of Windows VMs to the NFS Ganesha implementation. This means ALL traffic is going through the NFS containers created on the Ceph cluster, and I loose the distributed nature of the oVirt hosts talking direcly to the OSDs on the Ceph cluster. If I was to go this way, I should probably create some NFS Ganesha servers that connect to Ceph natively on the one end and provide NFS services to oVirt. Both tests would still test Ceph, but using an alternative method to CephFS. My preferred solution really is 1., was it not for the backup APIs being rendered useless. Is work still being carried out on development in these areas, or has oVirt/Ceph development ceased? Thoughts and comments are welcome. Looking forward to sparring with someone that has experience with this :-) With kind regards Jelle
