Hello,
Not sure about the feature part. I additionally tested this on oVirt 4.4.10.7-1.el8 and it
works fine even if cluster compatibility there is set to 4.6.
Engine:
MaxNumOfVmSockets: 32 version: 4.2
MaxNumOfVmSockets: 32 version: 4.3
MaxNumOfVmSockets: 32 version: 4.4
MaxNumOfVmSockets: 32 version: 4.5
MaxNumOfVmSockets: 32 version: 4.6
VM:
<vcpu placement='static' current='4'>32</vcpu>
Regards,
David
