Xen users - Jul 2011 - "xm dmesg" shows SVM but not /proc/cpuinfo

Ah, thank you for pointing that out.  I forgot to include a subject, my
bad.

You would probably get better answers if your post had a more
descriptive subject, other than "(no subject)"

Xen doesn''t passthrough some CPU capabilities to guests and so 
/proc/cpuinfo only lists the capabilities that the hypervisor supports 
in a virtualised environment.

Remember dom0 is a virtualised guest, so will not have VMX/SMX listed.

As long as xm dmesg lists SMX/VMX then the support is available to Xen 
at hardware level so HVM will be okay.
