[Xen-users] Long delay during boot of virtual machine when no CD in CD-ROM drive

[JÃrg Spilker <js@xxxxxxxxx>]

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

using xenstore-ls, i was able to recognize /vbd/2816 as the cd-rom device

this is part of my config:

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/cdrom,sr0:cdrom,r']


iÂm able to solve this problem when there is a disk inserted into the 
cd-rom device. But i think this is not an ideal solution. Is this the 
normal behaviour when propagating the cd-rom device of the host to the 
virtual machine? Are there better options to do this?
Greetings, JÃrg
