You'll get 'sda' if QEMU exposes the disks to the
guest as IDE or SCSI. 'vda' is for virtio block
devices. 'vda' should work so I would recommend
finding out why not rather than getting sidetracked
into a different kind of guest disk setup that might
not work either.

If you post a link to the full boot up log then that
will have enough information to tell whether the problem
is that your guest kernel doesn't have virtio support
built in or if something's wrong with your guest disk image.
