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.

Hi, thanks all for your comments.

Now, lets get the info u say running xm dmesg:

xm  dmesg | grep  VMX

(XEN) VMX: VPID is available.
(XEN) HVM: VMX enabled
(XEN) VMX: MSR intercept bitmap enabled

(XEN) VMX: VPID is available.
(XEN) VMX: VPID is available.
(XEN) VMX: VPID is available.
(XEN) VMX: VPID is available.
(XEN) VMX: VPID is available.
(XEN) VMX: VPID is available.
(XEN) VMX: VPID is available.

xm dmesg | grep HVM
(XEN) HVM: VMX enabled
(XEN) HVM: Hardware Assisted Paging detected and enabled.

This mean that I have my server ready for HVM?

Thanks!!!
