Subject: Run Xen on HVM guest?

Hi men,

I installed a HVM guest on Xen. And the results of 'cat /proc/cpuinfo'
are different on Dom0 and DomU(HVM).

The CPU mode is right on both:
  model name      : Intel(R) Core(TM)2 Quad  CPU Q9300  @ 2.50GHz
However, on Dom0 'flags' contains 'vmx', which is the key of HVM,
but on DomU, it doesn'e contains 'vmx'.

Does it mean that HVM DomU dose not support 'vmx', so we can't install
another Xen on HVM DomU?

I want to know the reason why the DomU didnot have 'vmx':
1. Intel VT doesn't support 'vmx' on DomU
2. Intel VT supports, but Xen doesn't support (now)
3. Other reason

Thanks,
Wu
