Heya,
I'm just trying to create a minimal(@core) Fedora 17 guest on F17 host, using Virt- preview.
So, once I create the minimal guest (using the attached script), the guest attempts to reboot, and it's just hung there, I could see that on the serial console. I tried to do a 'virsh list', it's just hung there too, When I tried to look into logs, I see a virsh segfault:

To avoid this, I have to stop libvirtd service (here, it takes a little while to stop the service. Then, again start the libvirtd service). Now, I can use virsh, and start the guest and see the boot progress via serial console.
Just wondering if it's a known issue, before I file a bug.
If needed, I can provide further debugging info by enabling LIBVIRT_DEBUG=1 on the shell when it hangs. Just let me know.

More specifically, 'virsh list' hangs when I shutdown the guest (I just ran 'init 0' inside the guest)

Nothing specific I see in '/var/log/libvirt/qemu/regular-guest-f17.log'
Attached stdout of 'virsh list' after enabling LIBVIRT_DEBUG=1.
Anyone else notice this?
