Comment 7 for bug 1286256

I'm experiencing this issue now. Nested KVM, libguestfs hangs and nova waits forever.

Interestingly, if I kill the first qemu-kvm process, the hanging libguestfs one, then nova proceeds to start up my instance without issue.

With a qemu wrapper that swaps in the Westmere cpu type, I can get the guestfs test tool to complete, but can't figure out how to make whichever openstack component that's responsible for kicking this off to use the wrapper.
