[Xen-users] vbd device failures

[Anand Kumria <wildfire@xxxxxxxxxxx>]

Hi,

I'm experiencing vbd device failures; it appears as if the device nodes
are being allocated but not de-allocated.

Initially the devices were marked as /dev/hda[1,2]; and when they failed to 
work I changed
them to be /dev/sda[1,2].  However I now find that I can no longer boot this 
domU 
irrespective of how I specify the disks.  As you can see at the end, the images 
themselves exist

I am running xen-3.0.0 built from source; any insight or suggestions 
appreciated.

varuna:~# grep "^disk" /etc/xen/fai-machine
disk = 
['file:/vserver/images/fai.img,hda1,w','file:/vserver/images/fai-swap.img,hda2,w']

varuna:~# xm create -c fai-machine
Using config file "/etc/xen/fai-machine".
Error: Device 770 (vbd) could not be connected. Backend device not found.

varuna:~# xm create -c fai-machine
Using config file "/etc/xen/fai-machine".
Error: Error creating domain: VM name 'fai' already in use by domain 21

varuna:~# xm destroy 21

varuna:~# xm create -c fai-machine
Using config file "/etc/xen/fai-machine".
Error: Device 2050 (vbd) could not be connected. Backend device not found.

varuna:~# grep "^disk" /etc/xen/fai-machine
disk = 
['file:/vserver/images/fai.img,sda1,w','file:/vserver/images/fai-swap.img,sda2,w']

varuna:~# ls -l /vserver/images/fai.img /vserver/images/fai-swap.img
-rw-r--r--  1 root root 4294967296 2006-01-04 04:26 /vserver/images/fai.img
-rw-r--r--  1 root root  524288000 2006-01-04 04:25 /vserver/images/fai-swap.img


Thanks,
Anand
