I have been trying to trace a problem when using Fedora's qemu with a pv guest which is that no graphics are available. I get the errors

xen be core: xen be: watching backend path (backend/console/2) failed
xen be core: xen be: watching backend path (backend/vkbd/2) failed
xen be core: xen be: watching backend path (backend/vfb/2) failed
xen be core: xen be: watching backend path (backend/qdisk/2) failed
xen be core: xen be: watching backend path (backend/qnic/2) failed

in the qemu log file in /var/log/xen . So far I have traced it to rbd support in qemu, because qemu-system-i386 built with the --disable-rbd does have working graphics. Does anyone have suggestions on what the problem might be, or how I might debug the issue further.
