[kernel-xen] Problems with HVM virtualisation on AMD boxes

[Steven Haigh]

Have a look at the output of 'xm info' - it will tell you what you can do.

 From memory, you won't see an svm tag when booting into the Xen 
hypervisor as that would indicate you could run a hypervisor within a 
hypervisor - which is not supported at this point.
