qemu disk-mounting issue on openSUSE

[Michael Hill <mdhillca gmail com>]

Below is the qemu command line followed by the last screenful or two
of output for four different attempts. I get similar results on F18,
but can still boot today's qemu img with "/dev/vda" using the last
host kernel I generated (2 Jan).

You might want to save "/run/initramfs/sosreport.txt" to a USB stick or /boot
after mounting them and attach it to a bug report.

To get more debug information in the report,
reboot with "rd.debug" added to the kernel command line.
