VT enabled in BIOS, still kvm says 'disabled by bios'

VT enabled in BIOS, still kvm says 'disabled by bios'

[Sukanto Ghosh]

Hi all,

On my system:

Processor: Intel Core 2 Duo 6300  1.86 GHz
Motherboard: Intel DG965RY
OS: Ubuntu 7.10 (Gutsy)
Linux Kernel:  2.6.22-14-generic
BIOS has VT technology 'enable/disable' feature.

'cat /proc/cpuinfo' shows 'vmx' flags.
I checked and enabled the VT support in the BIOS.

'modprobe kvm' runs fine.
But still 'modprobe kvm_intel' gives 'operation not supported' error.

(I issued both of them after 'su')

After looking into the /var/log/syslog, file I found that the message is 
'kvm: disabled by bios'.


I am puzzled, please help me out. What's going wrong ?



Thanks and Regards,

Sukanto Ghosh

Hi,

You need to go through a power-down/power-up cycle.
(See the help associated with the flag in the BIOS)

Thanks Laurent. I was always restarting the system.
I could successfully load kvm-intel module.

Thanks once again.
