libvirt domain log

If you setup F19 guest in Boxes, the guest hangs when you click 'Start using GNOME 3' in the initial setup UI shown on first login (its /usr/libexec/gnome-initial-setup if you want to run it manually after first login to test). Here is the warning that is shown on the Boxes console:

(gnome-boxes:20263): GSpice-CRITICAL **: cursor_handle_init: assertion `c->init_done == FALSE' failed

I know that guest is hung because I fail to change the VT using virt-manager's send-keys and the following command tells me that qemu itself is not hung:

$ virsh qemu-monitor-command --domain fedora19 --hmp info status
VM status: running

Here is the bt of qemu process I get by attaching gdb externally after the hang:
