Hello,
I work along with Moiz and here's what we tried.
We created a blank VM, loaded Windows 2016 ISO and booted it up. When we select the OS as
Windows 2016 x64 the ISO is loaded but the screen is stuck with the windows logo. The CPU
spikes up to 99%.
However if we select the OS as 'Other OS' the installation proceeds. We compared
the XML files in both cases and noticed that the below parameters are added when we select
the OS as windows 2016.
<hyperv>
<relaxed state='on'/>
<vapic state='on'/>
<spinlocks state='on' retries='8191'/>
<synic state='on'/>
<stimer state='on'/>
</hyperv>
<timer name='hypervclock' present='yes'/>
I guess this is expected because of the line "hypervEnabled =
vmInfoBuildUtils.isHypervEnabled(vm.getVmOsId(), vm.getCompatibilityVersion());" in
https://github.com/oVirt/ovirt-engine/blob/ovirt-engine-4.3/backend/manag...
However the question is why are the hyperv enlightenments causing a problem? The host
details are as below:

The CPU type in ovirt detects it as Intel Skylake-Server-noTSX-IBRS Family. We tried
changing the cpu type for the VM to broadwell and other types to no effect.
The ovirt version is 4.3.10.4-1.0.22.el7
