This could be simplified to:
if (ret == 0)
vm->updated = 1;
(no harm in re-setting it to 1 if it is already 1, and it can only be 0
or 1).
yeah, make sense.
Are you also missing an update when vcpus are modified? I'm wondering
if it would be better to make virDomainSaveStatus auto-set the updated
field, rather than making every call have to independently do it.
yeah, for vcpu hotplug, I think so, other vcpu updates are for
persistent change, no need to mark it as "updated".
It's better if we could make virDomainSaveStatus auto-set it, but
qemudDomainHotplugVcpus doesn't invoke virDomainSaveStatus.
