in case of '-smp 1' guest work as expected.

#! /bin/bash

export VGA="-vga vmware"
export NET=virtio

There are some known issues with KVM guests and soft lockups. Work is on-going upstream to make the guest-host interaction better so the guest doesn't hit this. For now, you can boot with nosoftlockup on the kernel command line. See https://bugzilla.redhat.com/show_bug.cgi?id=794478#c4 Also, given the host you reported against is F14 those fixes aren't going to make it to you at all. I'm going to duplicate your bug to 794478, as only a future release will wind up fixing this issue. *** This bug has been marked as a duplicate of bug 794478 *** |
