Re: [Xen-users] Problem with VT Enablement


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,

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 ??
