From: Adalbert Lazar <alazar@xxxxxxxxxxxxxxx>
The thread/worker receiving vCPU commands (from the guest introspection
tool) signals the vCPU by placing the command in a vCPU buffer, sets this
vCPU request bit and kicks the vCPU.
This patch adds the call to the introspection handler that will:
- execute the command
- send the results back to the introspection tool
- pause the vCPU (if requested)
