[ovirt-users] Re: Unable to start VMs after upgrade from 4.4.9 to 4.4.10

Hi, this is already fixed in oVirt 4.5 [0]. Possible workaround might be to downgrade the iproute-tc package below version 5.15.0-3. Regards, Ales [0] https://github.com/oVirt/vdsm/commit/503a98139d65daed856d97a8c6d7f875bcbe...

Using up to date CentOS Stream 8 with vdsm-4.40.100.2-1.el8 and oVirt 4.4.10. The VM is getting into unresponsive state during the power down if port mirror is activated in the vNIC profile of the VM. The supervdsm.log on the host is showing the following error during power off. This was working in < 4.4.10. So I would say that this is a bug. Where should I report this?
