Subject: [PATCH 5/6] run.py: Introduce --blk-disk argument

This new argument will create a new virtio-blk device, instead of the
scsi-blk that can be created by using --disk argument, accepting the
same argument of --disk.

By using --disk-blk "disk2=file1" will create
/dev/disk/by-id/virtio-disk.
