That's because "/proc/cpuinfo" only shows Xen dom0 Linux info,
which is a *VM* !

Xen *hypervisor* (xen.gz) uses VMX, so dom0 doesn't see it.
See "xm info" and check the caps, you should see hvm listed there.

Also read "xm dmesg" to see the Xen hypervisor boot messages.. 
there you should VMX/HVM getting enabled in the hypervisor.
