Upgraded to oVirt 4.4.9, still have vdsmd memory leak
by Chris Adams 09 Dec '21

09 Dec '21

I have seen vdsmd leak memory for years (I've been running oVirt since version 3.5), but never been able to nail it down. I've upgraded a cluster to oVirt 4.4.9 (reloading the hosts with CentOS 8-stream), and I still see it happen. One host in the cluster, which has been up 8 days, has vdsmd with 4.3 GB resident memory. On a couple of other hosts, it's around half a gigabyte. In the past, it seemed more likely to happen on the hosted engine hosts and/or the SPM host... but the host with the 4.3 GB vdsmd is not either of those. I'm not sure what I do that would make my setup "special" compared to others; I loaded a pretty minimal install of CentOS 8-stream, with the only extra thing being I add the core parts of the Dell PowerEdge OpenManage tools (so I can get remote SNMP hardware monitoring). When I run "pmap $(pidof -x vdsmd)", the bulk of the RAM use is a single anonymous block (which I'm guessing is just the python general memory allocator). I thought maybe the switch to CentOS 8 and python 3 might clear something up, but obviously not. Any ideas? -- Chris Adams <cma(a)cmadams.net>

ovirt 4.4.x series
by Nathanaël Blanchet 09 Dec '21

09 Dec '21

Hello, I found some informations about an upcoming ovirt 4.5 release based on centos stream 9. Considering that Centos stream 9 will not be stable before months, can we expect new 4.4.x releases following 4.4.9? -- 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

Downgrading qemu-kvm
by Gary Pedretty 09 Dec '21

09 Dec '21

So even the latest updated to qemu-kvm is still broken in regards to running VMs in Ovirt. I thought I would try Node on a new host and the current install iso, installs version 6.0 of kvm, which still works, but if you do an upgrade on the node host it sill updates to the latest 6.1 version of kvm. Question, how do you downgrade kvm on a node host, the regular yum downgrade does not seem to work on a node host. Gary _______________________________ Gary Pedretty Director of IT Ravn Alaska

oVirt host - yum dependency error

Hi I have an existing oVirt host 4.4 running on CentOS 8, and I am in the process of converting the OS to CentOS Stream. I am getting the following errors: ``` # yum update Last metadata expiration check: 0:03:14 ago on Wed 08 Dec 2021 01:05:55 AM CET.

Q35 with BIOS broken
by mediocre.slacker＠protonmail.com 08 Dec '21

08 Dec '21

I've been trying to get oVirt working for a week now with a self-hosted engine setup. Eventually, today, I decided to try a standalone engine and see if I can't at least get that to work, to maybe figure out what the issue is. It seems the default chipset type is Q35 with BIOS. But it fails to boot a VM. I'm not sure where to even look in the logs for this. The VM just never comes up, even though it's shown as being up in the oVirt administration page. I found similar symptoms when trying to set up a hosted-engine on the same machine. The VM would fail health check, and hosted-engine --vm-status would show the VM as up, but health check failing. The VM wasn't available over the network and it never pulled a DHCP lease from my router. I've looked at the logs pretty extensively and couldn't find anything to indicate what the cause of the problem was, or that this was even the problem in the first place. As far as the logs seem to be concerned, the VM is running fine, and it's a network issue.

Hi. I've Qemu/Libvirt from ovirt-release-master-4.5.0-0.0.master.20211206152702.gitebb0229.el9.noarch and it seems QXL is not there. Is that a fluke or intention? Do you have QXL working? many thanks, L.
