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?
