13.16 Online CPU migration for vPar
Online CPU migration is supported for vPars. An illustration is as follows.
NOTE: At each step, appropriate commands are executed to verify the CPU count on the vPar
and monitor the progress of the operation. Only the relevant output from each command is shown.
In this example, the VSP with several vPars and VM guests is configured as follows:
# hpvmstatus

Virtual Machine Name VM # Type OS Type State #VCPUs #Devs #Nets Memory
