Hello,

when starting a guest domain (using OpenSUSE 11.0 for host and guest) the startup process lasts very long. The logfile of the guest shows the following entries:

<4>XENBUS: Waiting for devices to initialise: 295s...290s...285s...280s...275s...270s...265s...260s...255s...250s...245s...240s...235s...230s...225s...220s...215s...210s...205s...200s...195s...190s...185s...180s...175s...170s...165s...160s...155s...150s...145s...140s...135s...130s...125s...120s...115s...110s...105s...100s...95s...90s...85s...80s...75s...70s...65s...60s...55s...50s...45s...40s...35s...30s...25s...20s...15s...10s...5s...0s...
<4>XENBUS: Device not ready: device/vbd/2816

The host device configuration for the guest is:

disk=[ 'phy:/dev/domX/daolin_root,sda1,w'
     , 'phy:/dev/domX/daolin_boot,sda2,w'
     , 'phy:/dev/domX/daolin_usr,sda3,w'
     , 'phy:/dev/domX/daolin_opt,sda4,w'
     , 'phy:/dev/domX/daolin_var,sda5,w'
     , 'phy:/dev/domX/daolin_src,sda6,w'
     , 'phy:/dev/domX/daolin_tmp,sda7,w'
     , 'phy:/dev/data/home,sda8,w'
     , 'phy:/dev/data/foto,sda9,w'
     , 'phy:/dev/data/imap,sda10,w'
     , 'phy:/dev/data/news,sda11,w'
     , 'phy:/dev/data/squid,sda12,w'
     , 'phy:/dev/data/srv,sda13,w'
#     , 'phy:/dev/hda1,sda14,w'
     , 'phy:/dev/cdrom,sr0:cdrom,r', ]
vif=[ 'mac=00:16:3e:35:55:5f', ]
vfb=['type=vnc,vncunused=1']

and the hosts log shows the following:

Aug 26 14:11:58 lotus logger: /etc/xen/scripts/block: add XENBUS_PATH=backend/vbd/4/2816 Aug 26 14:12:05 lotus logger: /etc/xen/scripts/block: Writing backend/vbd/4/2816/physical-device b:0 to xenstore. Aug 26 14:12:05 lotus logger: /etc/xen/scripts/block: Writing backend/vbd/4/2816/hotplug-status connected to xenstore.
Aug 26 14:12:05 lotus kernel: vbd vbd-4-2816: 2 creating vbd structure

All configured disks on the host are available on the guest and iÂm not able to identify the missing device. Is there any way to identify the source of the problem ?

Greetings, JÃrg
