On arm64 cluster trying to hotplug additional cpu sockets, causes hotplug failure and stuck migration job (stuck in running forever)

4.19

100%

1.create and start vm with sockets=1 and maxSockets=4 in cpu spec
2.edit vm cpu spec with sockets=2
3.wait for migration to happen

hotplug fails, migration job stuck

1.hotplug succeeds
2.if hotplug fails, proper error should be raised and migration job should be failed
