      Hi Everyone,

      I upgraded my CentOS 5.5 to Xen 3.4.2 using this guide:

http://www.syntaxtechnology.com/2010/01/upgrade-xen-3-0-on-centos-5-4-x
86 _64-to-xen-3-4-2/

      Now, using the new kernel that it gave me, the system doesn't seem
      to be able to detect vt-x..

      In virt-manager, Local Install Media and Network Boot are greyed
out..

      Any ideas?

      Thanks

Yes it does. It worked fine with the orignal version of Xen that came
with CentOS 5.5. It's a brand new server opened today from Dell which
support Vt-x and Vt-d. Virtualisation technology is enabled in the BIOS
You have the vmx flag in /proc/cpuinfo?
I suppose you had the VT extension enabled before the migration but
suppose you fiddled with it, power down your host (like shutdown and pull
the plug) and power it up again. I experienced this being necessary once
because simple rebooting after getting out of the BIOS did NOT enable VT
for real.

Nope, I don't have that flag in cpuinfo, but I can't understand why....
Is it possible that the kernel upgrade can disable this somehow??

It's really confusing me

I personally think not. Do the power recycle thing and check again. If you're
sure it's on in the BIOS. Ow yes, which reminds me, I once had a BIOS where it
needed to be enabled on two different spots - I think it was a HP machine.

Power cycling made no different. I had the plug out for about 2 or 3 minutes.

This is really starting to worry me why the vmx flag isn't showing...

I never checked for the vmx flag in the vanilla install, but since I was able to create an HVM guest, I image it would have been there?
