OK, I have a new 2.6.38 kernel with virtio_blk.ko.  This solves the failure
to find ext2 root device.

Still not having any luck running the test-tool to completion.  There is no
/sys in the guest root image. There is also no /etc/fstab (is that
expected?)  There is no ethernet interface even though it looks like it can
load virtio_net.
