If you want to use LACP with the native Linux bonding, then you need
to enable it in the native LACP bonding, not in OVS. (I don't know
whether this configuration works anyway; no one has reported testing
it.)

This is essentially the following FAQ. Tailored a little for your
case:
ovs-vsctl add-br cloudbr
ovs-vsctl add-port cloudbr bond0
ovs-vsctl add-port cloudbr vlan9 tag=9 -- set interface vlan9
type=internal
ifconfig vlan9 192.168.0.7
Q: Can I configure an IP address on a VLAN?
A: Yes. Use an "internal port" configured as an access port. For
example, the following configures IP address 192.168.0.7 on VLAN 9.
That is, OVS will forward packets from eth0 to 192.168.0.7 only if
they have an 802.1Q header with VLAN 9. Conversely, traffic
forwarded from 192.168.0.7 to eth0 will be tagged with an 802.1Q
header with VLAN 9:
ovs-vsctl add-br br0
ovs-vsctl add-port br0 eth0
ovs-vsctl add-port br0 vlan9 tag=9 -- set interface vlan9 type=internal
ifconfig vlan9 192.168.0.7
