Hello,
Is that possible to allow a single VCPU to run on multiple PCPUS, say 2
PCPUS. If so how can it be done. Do i need to modify any structures or have
a special code to parallelize VCPUs.
Thank you

Unless you explicitly pin a VCPU to a particular subset of PCPUs the
default is for a VCPU to be schedulable on any PCPU.

Obviously a single VCPU can only run on a single PCPU at a time.
