[Xen-users] Re: VT not recognized on Intel Xeon 5130

[Ralph Gauges <ralph.gauges@xxxxxxxxxxxxxxxxxxxx>]

Hi again,

it took me a while to resetup the whole machine since the integrated 
network interfaces are not supported in kernel 2.6.16.
But now the whole thing is up again, but it still shows the same 
problem. Xen is basically telling me that the CPU does not support VT or 
that it is not enabled in the BIOS. But I did enable it in the BIOS and 
/proc/cpuinfo show that the vmx feature is present in all four CPUs.
I am somewhat puzzled since it works on my Core2 Duo at home without 
problems.
Maybe someone else has had similar problems and can point me to where I 
did something wrong. Thanks a lot
Ralph
