Re: Host-passthrough CPU and migration
by Strahil
Ah... Never thought I can switch it to 'Auto'. Actually it makes sense - we can't be sure if all nodes in cluster are the same - like my case.
Now all VMs are in Auto mode.
Thanks for the clarification, Sharon.

Host-passthrough CPU and migration
by Strahil Nikolov
Hello Community,Dev,
does anyone know why only "Manual Migration" allows passing through the CPU from the Host to the VM ?
In many environments, the Clusters are having the same CPU model in order to avoid any issues. Have you observed any issues with that ?

Fedora 30 guest - kernel issue
by Giulio Casella
Hi everybody,
yesterday I updated some of my fedora 30 ovirt guest, and after reboot I
wasn't able to control consoles via spice: I could see desktop, but
mouse and keyboard were not working (nor were key command in
remote-viewer menu, like ctrl-alt-F2 and so on).
Let me specify it's not strictly an ovirt issue, and the problem goes
away booting with old kernel (kernel-5.2.18-200.fc30.x86_64): the
problem arises only with fedora kernel version kernel-5.3.6-200.fc30.x86_64.
So: anyone has already faced this, before I dive into logfiles?
TIA,
Giulio
