Kernel complains as:
VFS: Cannot open root device "vda" or unknown-block(0,0): error -6
when configured with CONFIG_VIRTIO_BLK=y according to README.
CONFIG_SCSI_VIRTIO=y is also needed to bring guest into disk fs.

I don't know how you generated this, but please use git. It's missing
a cut between the commit log and the diff, as well as a diffstat.
