Cluster and datacenter compatibility levels
by Colin Coe 15 Feb '22

15 Feb '22

Hi all I'm looking for a definitive answer on what each compatibility level means. Specifically, I'm looking for: - new features - deprecated features - removed features We're on 4.3 so I'm looking for the info above on 4.4, 4.5 and 4.6 My main motivation is to ensure we don't lose SPICE support. We actually use RHV and I logged a case with Red Hat GSS but couldn't get the info I was after. Thanks

vm seal
by Nathanaël Blanchet 14 Feb '22

14 Feb '22

Hello, I noticed that a vm created from a "sealed" template is initially mount on one host with libguestfs, with a virt-sysprep process, before getting ready to be used. This should be unuseful given that the template is already sealed. Is there a reason to that? -- Nathanaël Blanchet Supervision réseau SIRE 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

Moin, We have in our Environment 12 servers managed by one self hosted engine. It is ovirt 4.3.9. We are Freizeit on that Version. How did you make Backups? We use a github Script which generate via api a snapshot and Mount this disk into the vm where the backup Script is running. The backup Script Export this additional Hard disk to a storage and disconnect the disk and remove the snapshot. This works on Linux vm fine if they have Medium load. If we try this with a Windows 10 vm or Windows Server vm or a Linux vm with high load or with a very big Hard drive this will not work. Disk can't Export and snapshot will not delete. I have found winchin and bareos but I have not start to check this first I want to have some more possible options. Thanks Marcel

Hi Sandro, It seems that with https://github.com/oVirt/ovirt-site/commit/f3286b2e1f2871978d054250556f1b4f… all refference to Gluster & Hyperconverged is removed from the website. Can you clarify the situation with Hyperconverged deployments ? Best Regards,Strahil Nikolov

This works since 4.4.6, but was broken in 4.3. You should upgrade to 4.4 at this point. > I guess I could present the LUN to a VM and run NFS from there as an alternative option. Yes NFS works for ISO on data domain in 4.3. Nir

oVirt 4.3 - Fibre Channel Data Domain as ISO dump.
by Angus Clarke 14 Feb '22

14 Feb '22

Hello RE: oVirt 4.3 - Fibre Channel Data Domain as ISO dump. Thanks for letting me join the list. I added a fibre channel Data domain with a view to using it as an ISO dump however I cannot mount CDs to VMs with this error: "Error while executing action Change CD: Drive image file could not be found" A bit of reading suggests there is no way around this when using fibre channel data domains - is this the case? I guess I could present the LUN to a VM and run NFS from there as an alternative option. Thanks a lot Angus
