[Xen-devel] RE: 3.0.3rc2 BUG: LVM backed qcow image not working?

[Timo Benk <timo.benk@xxxxxx>]

Hi,

Sorry, small typo ...

i try to create a LVM backed qcow image, but it seems qcow does not
like LVM.

=== create qcow image LV ===
# lvcreate --name xendom_qcow --size 100G xenvol
# mkreiserfs /dev/xenvol/xendom_qcow
# mount /dev/xenvol/xendom_qcow /var/lib/xen/images

=== create base LV and fill with data ===
# lvcreate --name xendom_base_qcow --size 10G xenvol
# mkreiserfs /dev/xenvol/xendom_base_qcow
# mount /dev/xenvol/xendom_base_qcow /mnt
# tar cpjf domu-base.tar.bz2 -C /mnt

=== create file backed qcow image ===
# qcow-create 5120 /var/lib/xen/images/xengate_root.qcow
  /dev/xenvol/xendom_base_qcow
# xm block-attach Domain-0
     tap:qcow:/var/lib/xen/images/xengate_root.qcow xvda1 w 0
# mount /dev/xvda1 /mnt
[... mount is hanging forever ...]

# dmesg
[...]
ReiserFS: xvda1: checking transaction log (xvda1)
blk_tap: Can't get UE info

???

Greetings,
-timo
