You should be able to do that with the POSIX compliant domain ... If nit, it's better to open a bug so this behaviour is investigated further.

Re: oVirt/RHV 4.3.6: How to boot a Q35/UEFI VM from CD?
by Strahil 03 Nov '19

I have successfully managed to boot and install RHEL & openSUSE with Secureboot, but UEFI variables are not saved and requires some workarounds (there is a bug opened for that) to work. What exactly is your problem?

Re: [ANN] oVirt 4.3.7 First Release Candidate is now available for testing
by Strahil 02 Nov '19

02 Nov '19

I think I have a theory about ovirt1 , but I have to test it. 1. Ovirt1 has a team device controlled by NetworkManager , but in engine those interfaces are unused 2. I guess that when I recently 'reinstalled' the host from UI, the old teamports' ifcfg-<DEVICENAME> was moved to ifcfg-<DEVICENAME>-1 and the original file was left empty. 3. When the system rebooted, network.service rereads all ifcfg-* files and starts the team0 , but when NetworkManager reads the empty files - he alters the /etc/resolv.conf which leads to out-of-sync status. Still, this is only theory and as ovirt3 has no team device (plain gluster arbiter) - I'm not sure how close is this one.

How to change the CPU of the win10 virtual machine on ovirt-node from 2 cores to 8 cores?
by wangyu13476969128＠126.com 02 Nov '19

02 Nov '19

The version of The ovirt-engine is 4.3.5. I created a win10 virtual machine on ovirt-node, which is allocated 8 cores, and when using the virtual machine I found only 2 cores. I used the command "virsh edit win10" on ovirt-node to prepare to modify the CPU core. I was prompted to enter my username and password. I entered the username and password of the ovirt-engine web interface and ssh log in to the ovirt-node username root and password, but both prompt: Error: failed to connect to the hypervisor Error: authentication failed: authentication failed How can this problem be solved?

I'm not sure, but you can try with replica 1 gluster volume. Later that gluster volume can be changed to replica 2 arbiter 1 or even better replica 3 volume.
