Package: qemu-kvm
Version: 0.11.1+dfsg-1
Severity: normal
Hello,
networking does not come up on my machine. I changed the script
/etc/kvm/kvm-ifup to include two logging statements:
--------------------------------------- cut
#! /bin/sh
# Script to bring a network (tap) device for qemu-kvm up
# The idea is to add the tap device to the same bridge
# as we have default routing to.
switch=$(ip route ls | \
awk '/^default / {
for(i=0;i<NF;i++) { if ($i == "dev") { print $(i+1); exit; } }
}'
)
/sbin/ifconfig $1 0.0.0.0 up
logger -p daemon.info "kvm: found switch $switch"
# only add the interface to default-route bridge if we
# have such interface (with default route) and if that
# interface is actually a bridge.
if [ -n "$switch" -a -d /sys/class/net/$switch/bridge/. ]; then
/usr/sbin/brctl addif $switch $1 || :
logger -p daemon.info "kvm: added interface $1 to $switch"
fi
--------------------------------------- cut
My "normal" routing table looks like this:
$ netstat -rn
Kernel IP routing table
Destination Gateway Genmask Flags MSS Window irtt Iface
217.0.118.194 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.2.0 0.0.0.0 255.255.255.0 U 0 0 0 br0
0.0.0.0 0.0.0.0 0.0.0.0 U 0 0 0 ppp0
After starting a VM, I found this in my /var/log/daemon.log:
Mar 6 16:12:22 debian logger: kvm: found switch ppp0
This is obviously wrong. I suggest to check for bridge interfaces
instead of interfaces with a default route, and add the tapN interface
to that.
Kind regards,
