Ок. Modules have set m and y.

# lsmod | grep kvm
kvm                   516096  0
irqbypass              16384  1 kvm

Hmm...

# modprobe kvm_intel
modprobe: ERROR: could not insert 'kvm_intel': Input/output error

What? in BIOS virtualization enable. What the bug?

and lsmod | grep virtio is nothing.

What I need do? Please help me!

Re: KVM not supported???

I am going to close this thread.  Please continue on the linked thread.

I am not merging them as specific kernel versions are identified and I do not care to mix apples and oranges.
