Okay, here's another question that no one will be able to answer.

I have an OpenBSD HVM domU, and I wanted to mount its filesystem in
my Linux dom0.  The domU's disk lives on a logical volume.  Kpartx
does detect that partition 4 contains the disklabel, but that's as far
as I get.

I think my fedora kernel just doesn't support disklabels...

Anyone know how this is supposed to work?

check /boot/config-<yourfc6kernel> for CONFIG_BSD_DISKLABEL=X
as far as I know RHEL5 has it neither as module nor in-kernel and Fedora
has it as a module, so it's simply kldload, reading the mount error
messages and
off you go.

For the other posters...
the disk label defines slices, not partitions. those ain't extended
partitions either.
this is a different scheme than msdos's, a bit less stupid in it's design.

I don't have access to an SRPM or RPM capable box at this moment, but you might check out the centosplus kernels: they tend to track the RHEL kernels but turn on features like NTFS and possible this disklabel feature.
