In rare cases, when there are many vCMP guests, the last one may fail to start because there are not enough hugepages. The shortfall is between 5 and 20 hugepages. Occasionally, that lack is sufficient to prevent the last guest from starting.
vCMP guest fails to start.
The circumstances under which this occurs are not known, but appears related to a race condition related to memory handling.
Once in this state, restarting the host system clears the condition. Note: Restarting the vCMP guests does not clear the condition.
