the logical volume shows up as a hard drive during the installation of
the VM.  the issue i am having, though, is that, on the virtual hard
drive, i still need to partition (at least) a root and swap partition.
once i've done this, i am unable to see the VM's root and swap
partitions in the hypervisor's LVM--it is still showing up as one,
unallocated partition.

i want it to actually show up as a root and swap partitions so i can
work with them directly.

i found this[1] page in the libvirt documentation that may be what i
need.  as the documentation states, all i should need to do is provide
the name of my volume group.  but, i cannot get it to work: after i
define the XML file with virsh, the <pool> block disappears from the XML
file.  apparently i'm not defining it right, where is it supposed to go?
 i have tried putting it under the <domain> block as well as under the
<devices> block.
