[Xen-users] HVM on Dell Optiplex 755

["Hayawardh V" <hayawardh@xxxxxxxxx>]

Hi, 
I want to run a HVM domU. 

I have a Dell Optiplex 755:
model name    : Intel(R) Core(TM)2 Duo CPU     E4500  @ 2.20GHz

I have enabled VT in BIOS settings under performance. 
However, after I boot into a linux kernel (not under Xen), 

grep vmx /proc/cpuinfo returns nothing. 

When I boot under Xen, I get
(XEN) Intel VT-d has been enabled
(XEN) [VT-D]iommu.c:1700: Queued Invalidation hardware not found
(XEN) [VT-D]iommu.c:1708: Interrupt Remapping hardware not found

What do I do? 

Regards, 
Hayawardh
