This worked, thanks.  A couple of people emailed me separately on this.  For
others' reference, I added the following filter to lvm.conf on dom0 and
disabled the default "get everything" filter.  If anyone sees any pitfalls
with this regex, I'm sure you'll let me know.

(assuming your physical disks are sas/sata)

filter = [ "a/^/dev/sd*/", "r/.*/" ]

Thanks for the help,

-Iain
