Yes, each 'disk' defined in the guest config file maps to a single 
block device in the guest - hence they appear as distinct device nodes

Then you want multiple partitions instead of multiple disks.

Define a single disk file in the host & pass it to the guest, and within the
guest split it up into multiple partitions.  Nb, this doesn't prevent you
from accessing individual parititions in the host if you want to - see th
kpartx tool
