is it possible to build two privileged domain at boot time?
Hi All,
I am not very familiar with xen details. Now I am thinking of
building two privilged domain(domain 0 not driver domain) at boot time.
The other question is that wether it is possible to create another
domain 0 by domain-builder running in domain0? Does it make sense
when domain 0 is shut down unexpectedly another domain 0 can run at
once. Maybe it is absurd. I am looking forwards
