If Ben did, what I think is, a standard install, he created a LV and gave
it to virt-install with the CD for install. Windows would treat that LV as
a disk and create a partition table and then create an NTFS filesystem
inside that new partition. (from your responses, Chris, I'm guessing you
know this. I'm just prefacing my guesses to put my suggestions in context.)
In order to access the NTFS partition, you have to get Linux to read the
partition table from the LV and create new devices. (I'm guessing you know
this too, Chris, from your responses, but I think Ben might not be
understanding what really is going on).
Recently, I was required to expand a virtual drive/NTFS for a virtual
Windows XP machine. I documented my process, which includes using kpartx to
create a new device so the ntfs tools can see the nested partitions, at
http://wiki.centos.org/EdHeron/DomU_LVM_NTFS_resize. After posting it in
the doc list, a simpler suggestion was made that I have yet to test.
However, there are pieces there that might help Ben understand what is going
Ben, if this doc helps, let me know. Since it explains a little about
virtual machine nested filesystems and how to access them, I may change it
with that in mind.
