hmm?? |

Wikipedia says you have VT: |

In case this is because of modules problem: |
22 |
|
23 |
You have to en/dis/able: |
24 |
CONFIG_HAVE_KVM=y |
25 |
CONFIG_HAVE_KVM_IRQCHIP=y |
26 |
CONFIG_KVM=m |
27 |
# CONFIG_KVM_INTEL is not set |
28 |
# CONFIG_KVM_AMD is not set |
29 |
# CONFIG_KVM_TRACE is not set |
30 |
|
31 |
(Possibly reboot if compile is in wrong directory, or |
32 |
check /usr/src/linux points to correct version.) |
33 |
|
34 |
Then you emerge: |
35 |
app-emulation/kvm-kmod (and app-emulation/kvm :) |
36 |
|
37 |
It is now necessary to have CONFIG_KVM=m and the CPU-specifics OFF and |
38 |
use the modules from app-emulation/kvm-kmod. |
39 |
|
40 |
That results in: |
41 |
/lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kernel/arch/x86/kvm |
42 |
/lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kernel/arch/x86/kvm/kvm.ko |
43 |
/lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm |
44 |
/lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm/kvm.ko |
45 |
/lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm/kvm-intel.ko |
46 |
/lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm/kvm-amd.ko |
47 |
|
48 |
Which seems strange, but works :) |
49 |
(You load kvm-intel.ko which loads the correct kvm.ko) |
