Engine apparently cannot find a host with enough CPUs and free memory,
matching the NUMA and CPU pinning configurations, and having the given
host device available. According to the log, rvsh002 doesn't have the
host device, other hosts apparently don't satisfy some of the other
conditions. Also, isn't the VM pinned to some hosts?
Maybe someone could provide a better advice, but if you think there is a
host satisfying all the conditions, you can try to start the VM there
with "Run Once" and see if Engine provides a reason why it cannot be
started there.

Engine couldn't find a matching host so the VM is not attempted to start anywhere.
