oVirt gerrit 111079 0 master MERGED core: block cpu hotplug on uefi 2020-12-06 10:30:03 UTC

Description Arik 2020-09-01 14:26:13 UTC 
As long as CPU hotplug doesn't work (bz 1834250) we should block it on the engine side (even if it doesn't lead to VM crashes anymore).
Comment 1 Beni Pelled 2020-09-14 14:47:10 UTC 
Verified with:
- ovirt-engine-4.4.3.2-0.19.el8ev.noarch
- libvirt-6.6.0-4.module+el8.3.0+7883+3d717aa8.x86_64
- vdsm-4.40.29-1.el8ev.x86_64


Verification steps:
1. Create a VM with UEFI and start it
2. Add CPU (hotplug)

Result:
- The CPU isn't added and the following message appears in Event logs: 'Failed to hot set number of CPUS to VM bpelled_uefi_vm. Underlying error message: Hot plugging a CPU is not supported for a guest with UEFI.'
