Virtual machines are not moved from this host.
This may be because of problems with vMotion, DRS, or host compatibility. The following are the possible reasons:
vMotion is not configured or enabled on this host.
DRS is disabled for the virtual machines on this host.
Virtual machines on this host are not compatible with any other hosts.
No other hosts have sufficient resources for any virtual machines on this host.
Moving any virtual machines from this host would violate a VM/VM DRS rule or VM/Host DRS rule.
DRS is disabled for one or more virtual machines on the host.
A device is mounted to the virtual machine.
