[Pkg-xen-devel] Bug#437127: xen-utils-common: vif-common fails to identify ip address of ethernet device

[Stefan Tomanek]

Package: xen-utils-common
Version: 3.0.3-0-2
Severity: normal


On my systen, the script vif-common fails to retrieve the primary
IP address of my ethernet device, preventing a domU from starting.

I tracked this issue down to the file /etc/xen/script/vif-common.
The function ip_of uses the following shell code to extract the
address:

ip addr show "$1" | awk "/^.*inet.*$1\$/{print \$2}" | sed -n '1 s,/.*,,p'

This code however fails if no slash is present in the address, which
is the case in my configuration:

stefan at datenbruch:/etc/xen/scripts$ ip addr show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,10000> mtu 1500 qdisc pfifo_fast qlen 1000
    link/ether 00:16:17:90:b4:35 brd ff:ff:ff:ff:ff:ff
    inet 88.198.12.XXX peer 88.198.12.XXX/32 brd 88.255.255.255 scope global eth0
[...]

I changed the line to:

ip addr show dev $1 | awk '/^ *inet / {print $2; exit}' | sed 's#/.*##'

This works fine for me. Hopefully this special case gets taken care of in future
releases.
