Comment 1 for bug 2039803

setting this to medium instead of high as we have a workaround config option that will provide an escape hatch for those how encounter this on upgrade however this is important to fix and backport.

the bug is cause because we are using a different method to select the gpus CPU when creating the VM vs when live migrating the VM

we should use the same method in both cases and since we have moved to using domcaps as the new way for gust CPU selection we should consolidate on that for CPU compare too.
