Yes. It's stored on disk to the file specified on startup. On XenServer, they
assume there's no persistence across reboots, so the init scripts jump through
some hoops to clean out those entries. Obviously you can do the same for your
Xen integration if it's needed.

Here's the relavent code in "xenserver/etc_init.d_openvswitch":
start_ovsdb_server
$vsctl --no-wait init
if [ ! -e /var/run/openvswitch.booted ]; then
touch /var/run/openvswitch.booted
for bridge in $($vsctl list-br); do
$vsctl --no-wait del-br $bridge
done
fi
This just cleans up the bridges and the ports attached to them, which may be
sufficient. The ovs-vsctl command can be used to delete and modify other
entries if you need them. Let us know if you any particular questions.
