In dom0:

sirius:~# lvs|grep ws1
  ws1.mirror      vm   -wi-ao  30,00G
  ws1.raiz        vm   -wi-ao   5,00G
  ws1.space       vm   -wi-ao   5,00G
  ws1.swap        vm   -wi-ao 256,00M

sirius:/etc/xen# cat ws1|grep phy
disk = [ 'phy:vm/ws1.mirror,hda3,w',
  'phy:vm/ws1.raiz,hda2,w','phy:vm/ws1.swap,hda1,w' ]

In domU:

ws1:~# cat /proc/partitions
major minor  #blocks  name

   3     3   31457280 hda3
   3     2    5242880 hda2
   3     1     262144 hda1
   3     4    5242880 hda4

It appears to recognize the new lvm-backed vbd, but I can't access to
it:

------------------------------------------------------------------------
ws1:~# mkfs.reiserfs /dev/hda4
mkfs.reiserfs 3.6.19 (2003 www.namesys.com)

A pair of credits:
Jeremy  Fitzhardinge  wrote  the  teahash.c  code  for  V3.  Colin Plumb
also contributed to that.

Yury Umanets  (aka Umka)  developed  libreiser4,  userspace  plugins,
and  all userspace tools (reiser4progs) except of fsck.

Stat of the device '/dev/hda4' failed.
------------------------------------------------------------------------
ws1:~# fdisk /dev/hda [TAB][TAB]
hda1  hda2  hda3
ws1:~# fdisk /dev/hda

Daniel
