|
|||
Simple setup for connecting openvswitch to qemu/kvm
|
||||
===================================================
|
||||
This example brings up openvswitch using a private network.
|
||||
|
||||
Preliminary notes
|
||||
=================
|
||||
1. Make sure to build kernel support for openvswitch as a module. The
|
||||
openvswitch init scripts expect to load a module and upon success
|
||||
continue to setup the switch. If openvswitch is compiled
|
||||
statically, the init scripts not load the ovs-vswitchd daemon
|
||||
and none of the configured bridges will show up in the interfaces
|
||||
table (ifconfig). You can get around this limiation by running the
|
||||
following by hand:
|
||||
# ovs-vswitchd --pidfile --detach
|
||||
|
||||
2. Verify that ovs-vswitchd is running before proceeding:
|
||||
# /etc/init.d/openvswitch-switch status
|
||||
ovsdb-server is running with pid 1867
|
||||
ovs-vswitchd is running with pid 1877
|
||||
|
||||
3. A kernel and rootfs is required for qemu bring up.
|
||||
|
||||
Qemu Setup
|
||||
==========
|
||||
The host requires a /etc/qemu-ifup script to setup the bridging and tap
|
||||
devices. Qemu will invoke this qemu-ifup script at startup. Here is
|
||||
an example script:
|
||||
$ cat /etc/qemu-fup
|
||||
#!/bin/sh
|
||||
# the tap is dynamically assigned and passed into this script
|
||||
# as a parameter
|
||||
TAP=$1
|
||||
|
||||
# Note: if booting over NFS, once the $ETH0 device is added to the bridge,
|
||||
# your host will be unusable. In that case, setup networking
|
||||
# init scripts appropriately and change the following to work
|
||||
# with it.
|
||||
ETH0="eth1"
|
||||
NETMASK=255.255.255.0
|
||||
IP=192.168.1.1
|
||||
GATEWAY=
|
||||
SWITCH=ovsbr0
|
||||
if [ -n "$TAP" ];then
|
||||
ifconfig $TAP up
|
||||
ifconfig $SWITCH down &>/dev/null
|
||||
ovs-vsctl del-br $SWITCH
|
||||
ovs-vsctl add-br $SWITCH
|
||||
ifconfig $ETH0 0.0.0.0
|
||||
ifconfig $SWITCH $IP up netmask $NETMASK
|
||||
#-- external access not required for this test.
|
||||
#route add default gw $GATEWAY
|
||||
ovs-vsctl add-port $SWITCH $ETH0
|
||||
ovs-vsctl add-port $SWITCH $TAP
|
||||
exit 0
|
||||
else
|
||||
echo "$0: No tap device"
|
||||
exit 1
|
||||
fi
|
||||
|
||||
Start Qemu
|
||||
==========
|
||||
This example will bring up qemu with a tap network interface.
|
||||
Note: this command must be run as root due to the networking setup.
|
||||
|
||||
$ qemu-system-x86_64 -nographic -k en-us -m 1024 \
|
||||
-net nic,macaddr=1a:46:0b:ca:bc:7a,model=virtio \
|
||||
-net tap -enable-kvm\
|
||||
-kernel /opt/dpdk-guest-kernel \
|
||||
-append 'root=/dev/vda ro console=ttyS0' \
|
||||
-drive file=/opt/intel-xeon-core-ovp-kvm-preempt-rt-dist.ext3,cache=none,if=virtio
|
||||
|
||||
Once the guest OS is up and running, configure the quest network interface:
|
||||
$ ifconfig eth0 192.168.1.10
|
||||
|
||||
Ping the bridge:
|
||||
$ ping 192.168.1.1
|
||||
|
||||
From the host, view the bridged network:
|
||||
$ ovs-vsctl show
|
||||
c1212b96-ef49-4a8e-b598-09b05b854dd0
|
||||
Bridge "ovsbr0"
|
||||
Port "tap0"
|
||||
Interface "tap0"
|
||||
Port "eth1"
|
||||
Interface "eth1"
|
||||
Port "ovsbr0"
|
||||
Interface "ovsbr0"
|
||||
type: internal
|
||||
|
||||
At this point, openvswitch is up and running. If you want external
|
||||
network access, you need to set a GATEWAY in the qemu-ifup script and
|
||||
make sure the external device is part of the bridge.
|
||||
|
||||
Note:
|
||||
Proper setup will require a /etc/qemu-ifdown script to tear down the
|
||||
bridge and interfaces. (not provided here).
