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.
