Fedora xen - Apr 2006 - RE: running 32-bit paravirtualized DomU under 64-bit Dom0

Hi Matthias,

The first step your trying is okay: either IA32 or X86_64(EM64T)
full-virtualization VMX can run in X86_64 Host.

But IA32 paravirtulization XenU can only run in IA32 Xen0. :)

Best Regards,
Yongkang (Kangkang) 永康
