Xen in routed mode: start fails

When Xen is configured in routed mode, restarting xend fails because the script hotplugpath.sh is missing.

~ # /etc/init.d/xend restart

I'm using Debian Squeeze and XEN 4.0

Any idea?

It was a packaging bug. It can be worked around by install xen-utils-common from testing, or else creating the file by hand:

$ cat /etc/xen/scripts/hotplugpath.sh 
SBINDIR="/usr/sbin"
BINDIR="/usr/bin"
LIBEXEC="/usr/lib/xen/bin"
LIBDIR="/usr/lib64"
SHAREDIR="/usr/share"
PRIVATE_BINDIR="/usr/lib64/xen/bin"
XENFIRMWAREDIR="/usr/lib/xen/boot"
XEN_CONFIG_DIR="/etc/xen"
XEN_SCRIPT_DIR="/etc/xen/scripts"
XEN_LOCK_DIR="/var/lock"
