An ioemu (the device emulator of HVM guest) can run in Dom0.
An ioemu can also run in a per-hvm-domain stubdomain (namely, the "HVM emulation domain").
Stubdomain is a very small domain running mini-os.
In this way, we can achieve "a better scalability, performance and security...".
The architectures of ARM and x86 are different. Unmodified ARM guest can't run on x86 Xen.

Sorry, maybe a stupid question.

Xen 3.3.0 has a new feature:

- HVM emulation domains ('qemu-on-minios') for better scalability,
performance and security.


Does that mean we can create multiple HVM domains to run unmodified ARM os on an X86 server using Xen3.3?
