After enabling in the bios, be sure to actually power off your machine for 10 seconds, don't just do a soft reset or the VT setting may not be implemented.
Hi all
We have an issue about xen. We test XEN 3 on an Intel VT machine (Dual-Core Intel® Xeon® Processor 5100 Series), on SUSE Linux Enterprise Server 10.
After we boot from the XEN kernel, we started to configure a new 
Microsoft Windows guest machine by selecting 
Full Virtualization in YaST. After completing configuration using YaST and try to start the guest machine, An error message:
"Not an HVM capable platform, we stop creating!"knowing that VT is enabled in BIOS.
We tried to do some test to check if VT is enabled:
# xm dmesg|grep VMX
(XEN) VMX disabled by Feature Control MSR.
(XEN) VMX disabled by Feature Control MSR.
(XEN) VMX disabled by Feature Control MSR.

- 
Is the VT enabled by default in XEN kernel? -
 If Not, Is there any method to enable VT in Kernel?
