@DaanHoogland The host check you are referring to existed even before this
PR. One reason for the check is to ensure that the VM has not moved to another
host since the time it was fetched using listByHostId(). If it has moved to
another host (and vmsync has updated the host id) then no need to perform
restart/HA.
