Title:
qemu guest hangs on nested kvm startup with host kernel oops
Status in linux package in Ubuntu:
Fix Released
Status in linux source package in Utopic:
In Progress
Bug description:
I'm creating a vivid qemu guest on a trusty host with
3.13.0-48-generic kernel. When I start a guest inside that guest, I
get the oops below on the host while the first guest hangs and must be
(virsh) destroyed.
