Public bug reported:
Binary package hint: python-vm-builder
When using the --raw option with an LVM volume as the target to create a
VM, the default size is 5G. This isn't a problem if rootsize + swapsize
+ optsize falls within 5GB, but if you exceed the 5GB default size,
vmbuilder throws an exception (shown below). To make this concrete here
is what I am trying to do. I create a logical volume with size 10GB,
and on this I would like to have an 8GB root and 2GB swap partition.
There should be enough space, but I'm being told otherwise. There
should be a way to specify the size of the raw device, or simply ignore
the size when raw is being used. I can work up a patch to add a size
option to the command line if it would help.

Expected outcome: VM successfully created on the LVM partition that was
previously allocated.
Actual outcome: Exception thrown due to an incorrect assumption about the size
of the raw device.
