You're already running the Xen kernel and your view of /proc/cpuinfo 
is from the dom0, right?

I don't think you can see the vmx (Intel) or svm (AMD) flags from 
dom0, but the underlying hypervisor should be able to see it. Try

   sudo xm dmesg | grep -i hvm

You should see something like "(XEN) HVM: VMX enabled".

Alternatively, try booting into a non-Xen kernel and taking another 
peek at /proc/cpuinfo.
