[Xen-users] Mounting LVM sub-partitions

[Kevin DeGraaf <kevin@xxxxxxxxxxxx>]

I have a number of normal (paravirtualized) domU guests with LVM-backed
filesystems.  Each of these filesystems has an entry in (e.g.) /dev/vg0,
and can be mounted without issues.

However, I'm having trouble mounting the LVM-backed filesystems of the
HVM domU guests, because the LVM logical volumes in question don't hold
filesystems directly, but rather act as virtual disks with their own
partition tables, MBRs and (virtual) partitions.

The fdisk, cfdisk, and sfdisk programs all grok this scheme and, when
invoked on (e.g.) /dev/vg0/lv0, cheerfully report partitions of lv0p1,
lv0p2, etc.

However, there are no device node entries (either in /dev/vg0 or
/dev/mapper) for these sub-partitions, and thus mount(8) is unable to
use them.

I'm sure that I'm missing something simple, but my Googling hasn't
turned up anything.  Thanks in advance.
