Hello.
I have a DELL T5400.
Intel E5440
When it is with one CPU E5440 - I can run vm.
When it has both E5440 CPUs - it generates this error and the vm doesn't run.

TASK ERROR: KVM virtualisation configured, but not available. Either disable in VM configuration or enable in BIOS.

The bios configuration is OK.

Updated to the latest for this model.

These processors have VT, but it's not complete.
