Just 2010 is sufficient.

That 1GB capacity at odds with the statement in conf/default.cfg that
block devices need only be 512 MB.  Can we get by with a smaller qcow
image here, or does the config file minimum size limit need to be
raised?  Also, it would still be nice to follow through with the idea
that host_block_devices in the config file list both device name and
size, to avoid unintentionally trashing the wrong device.
