[Xen-users] VT option is on but 'VMX enabled' is not displayed in xm dmesg

[dongkyu lee <dongq.lee@xxxxxxxxx>]

We have 35 xen-installed servers and enabled VT to use HVM. Five of these servers do not show
any messages about vmx when 'xm dmesg | grep vmx' is entered but other thirty servers shows message correctly like below:

(XEN) VMX: Supported advanced features:
(XEN) VMX: EPT is available.
(XEN) VMX: VPID is available.
(XEN) HVM: VMX enabled

Even if five servers do not display 'vmx enabled' messages, 'xm info' command shows that 
xen_caps : xen-3.0-x86_64 xen-3.0-x86_32p hvm-3.0-x86_32 hvm-3.0-x86_32p hvm-3.0-x86_64 

I have tried to create HVM serveral times on these servers and they worked perfectly. 

Finally, everything is fine but no 'VMX enabled' message even if VT is enabled.
Any comments/hints would be greatly appreciated. Thank you.
