Hello everyone!

In my opinion, I think when we shutdown the GuestOS,
 Xen should free allocated vcpu and domain gived to GuestOS 
when it created at the same time. 

But I donât find any code in functions associated with shutdown process to
show this work,
for example: 
Hvm_vcpu_down()-ãdomain_shutdown()->__domain_finalise_shutdown()

But I find the functions free_vcpu_struct() and free_domain_struct() 
in the function complete_domain_destroy() in the process of destroy
operation, 
the code process is:
Domain_kill()->put_domain()->domain_destroy()->complete_domain_destroy()

Is that process right? Is there any relationship between them?
Does anyone know it?

Thanks for your help!
