Hi,

i just got a brand new IBM/Lenovo ThinkVista System with a Pentium D and installed fedora on it to use xen. i enabled the VT Stuff in the bios and the CPU has vmx capabilities. output of cpuinfo :

cat /proc/cpuinfo

vendor_id       : GenuineIntel

if i now try to start a vmx domain i get an error and found the following entry in xend-debug.log :

Traceback (most recent call last):

    raise VmError("Not an HVM capable platform, we stop creating!")
VmError: Not an HVM capable platform, we stop creating!


for me it looks like xen can't find the vt extension on this box ..

any hints ??
