The Windows VM is in a group that is a member of two different host affinity rules.
As a result, the VM can only run on hosts that satisfy both rules.
DRS Host Group 1

esxi-03a
esxi-04a
esxi-05a
DRS Host Group 2
While the different sorts of rules that DRS supports provide lots of l exibility, there might be
times when you need an even greater granularity. To satisfy that need for granularity, you can
modify or disable DRS on individual VMs in the cluster.
Configuring DRS VM Overrides
Although most VMs should be allowed to take advantage of the DRS balancing act, administra-
tors may be adamant that certain enterprise-critical VMs are not DRS candidates. However, the
