Hi,
could you send your domU config please?
I assume the disk entry is garbled. If your vg is named LVM and your
lv's are named LV1 and LV2 this line reads e.g.
disk = [ 'phy:/dev/LVM/LV1,xvda1,rw','phy:/dev/LVM/LV2,xvda2,rw' ]
cheers

Hi,
I'm having difficulty understanding why my domU image will not boot if
there are more than 1 disk device from the same LVM volume group
allocated to a domU.
For example:
The basic diagram below tries to show how my disk stacking is setup.
------------------------
| / | /usr |
------------------------
| domU |
------------------------
| xvda1 | xvda2 |
------------------------
| LV1 | LV2 |
------------------------
| LVM |
------------------------
| /dev/drbd0 |
------------------------
| /dev/sda1 |
------------------------
For some reason creating a domU in this configuration results in a message;
"Error: Device 51729 (vbd) could not be connected. Hotplug scripts not
working. "
in the logs there are entries with;
"[2008-07-23 14:51:58 xend 8058] DEBUG (blkif:24) exception looking up
device number for xvda1: [Errno 2] No such file or directory:
\047/dev/xvda1\047"
"[2008-07-23 14:51:58 xend 8058] DEBUG (blkif:24) exception looking up
device number for xvda2: [Errno 2] No such file or directory:
\047/dev/xvda2\047"
But if I boot a domU with only 1 logical volume assigned to the domU
(see diagram below) the VM boots without problems.

| / |
-------------
| domU |
-------------
| xvda |
-------------
| LV1 |
------------------------
| LVM |
------------------------
| /dev/drbd0 |
------------------------
| /dev/sda1 |
------------------------
I have trolled the net looking for some answers but none seem to provide
one. Any help on what may be the cause would be greatly appreciated. I
can provide config examples if that will help, but at this stage I'm
thinking it may be a bug and not wrong configuration. I may be wrong
though :)
Thanks.
