how are you starting qemu-kvm, is the host OS x86 or x86_64, is the guest OS x86 or x86_64, what build options were used for the qemu packages...hrmm, sorry, just tossing questions out as they come to mind.
i don't know if disabling 32bit emulation support in the kernel would affect this.
Actually, what kernel build did you update *from* ? I'm on 2.6.36-zen1 at the moment for my host OS, and my guests are working without issue, is why I ask; I don't know if you upgrade just from .36, or from something much earlier.
I guess the other thing to check, what does this show for you:
| Code: |
# ls -alh /dev/kvm
crw-rw----+ 1 root kvm 10, 232 Mar 5 21:04 /dev/kvm
|
(controlled by presence of kvm-amd or kvm-intel driver)
I don't know how it determines kvm_available, but I would assume it's doing a check for /dev/kvm (though this may be a crackpot assumption):
| Code: |
if (!kvm_available()) {
printf("KVM not supported for this target\n");
}
