Package: kvm
Version: 18-1
Severity: normal
Hello,
kvm-ifup tries to bridge the network interface of the virtual machine
with the interface used for the default route.
To extract interface name it uses this instruction:
switch=$(/sbin/ip route list | awk '/^default / { print $NF }')
i.e. it uses the last field of the default route. This works as long as
the route is simple enough, e.g.:
default via 10.0.0.138 dev br0
On my system the default route has both an explicit metric and a realm,
so it looks like this:
default via 10.0.0.138 dev br0 metric 1 realm 10
Since the output of 'ip route ls' does not have a fixed format I suggest
to use the following awk program:
switch=$(ip route ls | awk '/^default / { for(i=0;i<$NF;i++) { if ($(i) ==
"dev") print $(i+1) }}')
which matches the default route and prints the field following the 'dev'
token (which is always the interface name).
