Re: [Xen-users] Problem with VT Enablement

[Sven Oehme <oehmes@xxxxxxxxxx>]

i know, and i wrote that already above
the cpuinfo output :-)

my Problem is not the vmx flag, the
problem is i get the following error, while creating a new full virtualized
instance :

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

which i assume is ok , because i get "(XEN) VMX disabled
by Feature Control MSR" at boot time.

but why do i get "(XEN) VMX disabled by Feature Control
MSR" ??

VT is enabled in the BIOS and i see the vmx flag, so it
should work, but it doesn't .
should i open a bug for this ?

vmx is mentioned in the cpu flags, so it does see your
vt...

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 :

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):

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

any hints ??
