Thanks Laine, I now have it working. After applying the changes you
recommended, I had to change apparmor settings as libvirt was in enforce mode:
root@qemu-kvm:~/openvswitch# aa-complain /etc/apparmor.d/*
Setting /etc/apparmor.d/sbin.dhclient to complain mode.
Setting /etc/apparmor.d/usr.bin.evince to complain mode.
Setting /etc/apparmor.d/usr.lib.libvirt.virt-aa-helper to complain mode.
Setting /etc/apparmor.d/usr.lib.telepathy to complain mode.
Setting /etc/apparmor.d/usr.sbin.cupsd to complain mode.
Setting /etc/apparmor.d/usr.sbin.libvirtd to complain mode.
Setting /etc/apparmor.d/usr.sbin.rsyslogd to complain mode.
Setting /etc/apparmor.d/usr.sbin.tcpdump to complain mode.

Domain installation does not appear to have been successful.
If it was, you can restart your domain by running:
virsh --connect qemu:///system start DSL2
otherwise, please restart your installation.

There is nothing in this command line to say that the bridge is an openvswitch
bridge, so libvirt is attempting to treat it as the default Linux host bridge
type.
As a matter of fact, as far as I know virt-install hasn't been enhanced to
support direct description of an openvswitch bridge on its commandline.
The best way to solve this problem is to create a libvirt network to
encapsulate the openvswitch bridge, then tell virt-install to use that network.
1) Put the following xml into a file (e.g. /tmp/ovsnet.xml):
<network>
<name>ovs-br0</name>
<forward mode='bridge'/>
<bridge name='br0'/>
<virtualport type='openvswitch'/>
</network>
2) define and start the network:
# virsh net-define /tmp/ovsnet.xml
# virsh net-start ovs-br0
# virsh net-autostart ovs-br0
3) run virt-install telling it to use the network "ovs-net":
# virt-install --connect qemu:///system --name DSL2 --ram 1024 --vcpus 1 \
--disk path=/tmp/dsl2,size=1,bus=virtio,cache=none \
--network=ovs-br0 \ <======= THIS LINE IS CHANGED.
