[Pkg-xen-devel] Bug#638152: Error: Device 51712 (vbd) could not be connected. Hotplug scripts not working.
Package: xen-utils-4.0
Version: 4.0.1-2
Severity: normal
This issue is similar to
http://lists.alioth.debian.org/pipermail/pkg-xen-devel/2011-March/003217.html
but since I was not able to find a bug report I'm reporting this now.
Steps to reproduce:
1) cat << EOF > config
name = 'squeeze64'
vcpus = '4'
memory = '512'
disk = [ 'file:/home/lindi-sudo/squeeze64/disk.img,xvda,w' ]
EOF
2) xm create -c config
Expected results:
2) the domain boots
Actual results:
2) pygrub shows "Debian GNU/Linux, with Linux 2.6.32-5-amd64"
correctly but after a long timeout it prints
Error: Device 51712 (vbd) could not be connected. Hotplug scripts not working.
and exits.
More info:
1) the same configuration and image boot on a different amd64 squeeze
system.
2) sudo udevadm monitor does not print anything on the failing system
but prints

5) this is a desktop system so there's some "extra" stuff running
but
for reliability I've stopped network-manager however for now and
switched to static configuration:

Assuming 2.6.32 (squeeze) based do you have the xen-blkback/blktap modules (and any other backend modules) loaded? What udev rules do you have? What is present in /etc/xen/scripts? There's usually a logfile called xen-hotplug or something along those lines -- does that show anything? Does xenstore-ls show the backends under /local/domain/0/backend and the frontends under /local/domain/<domid>/device? Did this work previously on this machine (i.e. is this an new issue after an upgrade or a fresh install etc). [...]> 3) > > $ grep -vE "(^#|^$)" /etc/xen/xend-config.sxp > (network-script network-bridge)May or may not relate to this issue (probably not) but I'd normally recommend not using network-script at all and rather configuring your /etc/network/interfaces as per http://wiki.xen.org/xenwiki/HostConfiguration/Networking Ian. -- Ian Campbell You are always doing something marginal when the boss drops by your desk.

Hi,
inspired by
http://www.2virt.com/blog/?category_name=xen
I ran
#!/bin/bash
function dumpkey() {
local param=${1}
local key
local result
result=$(xenstore-list ${param})
if [ "${result}" != "" ] ; then
for key in ${result} ; do dumpkey ${param}/${key} ; done
else
echo -n ${param}'='
xenstore-read ${param}
fi
}
for key in /vm /local/domain /tool ; do dumpkey ${key} ; done
and got
