Try Bing=E2=84=A2 now hmm?? Wikipedia says you have VT: http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Harperto= wn.22_.28standard-voltage.2C_45_nm.29 In case this is because of modules problem: You have to en/dis/able: CONFIG_HAVE_KVM=3Dy CONFIG_HAVE_KVM_IRQCHIP=3Dy CONFIG_KVM=3Dm # CONFIG_KVM_INTEL is not set # CONFIG_KVM_AMD is not set # CONFIG_KVM_TRACE is not set (Possibly reboot if compile is in wrong directory, or check /usr/src/linux points to correct version.) Then you emerge: app-emulation/kvm-kmod (and app-emulation/kvm :) It is now necessary to have CONFIG_KVM=3Dm and the CPU-specifics OFF and use the modules from app-emulation/kvm-kmod. That results in: /lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kernel/arch/x86/kvm /lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kernel/arch/x86/kvm/kvm.ko /lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm /lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm/kvm.ko /lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm/kvm-intel.ko /lib/modules/2.6.30-tuxonice-r5.mayo.nofb/kvm/kvm-amd.ko Which seems strange, but works :) (You load kvm-intel.ko which loads the correct kvm.ko) Bye, Daniel --=20 PGP key @ http://pgpkeys.pca.dfn.de/pks/lookup?search=3D0xBB9D4887&op=3Dget # gpg --recv-keys --keyserver hkp://subkeys.pgp.net 0xBB9D4887 --=-7UQpMULQcwXGHX/qoEpq Content-Type: application/pgp-signature; name="signature.asc" Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.11 (GNU/Linux) iEYEABECAAYFAkq7mzYACgkQg3+4tbudSIdFRwCfc9yu6XzTpN+1uD/oPzmYhpv4 L6MAn3EyOePR2Drs8gmgC6jZ25FVNdDa =kx7G -----END PGP SIGNATURE----- --=-7UQpMULQcwXGHX/qoEpq--
