but I seem to need individual partition images for my

I somehow oversaw this: why do you think you need a specific
partitioning style because of using pv instead of hvm?
Or is this a xenman-specific thing?
How can I get the disk and swap partitions onto the file image or LVM image, and access them from Dom0 when setting things up or doing recovery options, without having a VT or HVM capable system and booting from a CD or network?

If you have a disk image which contains a nested partition table, then
the 'lomount' tool makes it easy to access individual partiitons. If
you further have LVM in the guest, then the kpartx tools can be used.
For example, I have /dev/HostVG/XenGuest1 which I map through to a
guest as /dev/xvda. In the guest I partitioned this into 2 paritiions,
one for /, and one for /boot. If I want to access /boot directly from
the host, I can use:
Thanks for the pointer. Hmm. The tool doesn't sem to be well documented. In fact, the RPM's for RedHat/CentOS don't have the docs at all. There's an option to compile them as part of the "-devel" RPM, but it didn't work well with 3.0.3.

If I submit some patches to separate out most of the docs into a "-docs" RPM, I wonder what are its odds of being accepted?



 lomount -diskimage /dev/HostVG/XenGuest1 -partition 2 /mnt/
