Hi Ingo,
When using an 64bit ( didn't got time to test 32bit now ) kernel[1] with PAT enabled , kvm-intel
does not work anymore.
When modprobing kvm-intel , kvm is saying VT extension is disable by BIOS which isn't true.
When disabling PAT again ( no changes to BIOS ) kvm-intel works again here.
Is that an known problem ?
If you need more infos just let me know.
