Hi,
I tried to use OVN with Openstack, but I ran into an Issue.
I use the OVN packages from the Canonical Cloud archive:
On the controller node:
ii ovn-central 2.6.0-0ubuntu2~cloud0
amd64 OVN central components
ii ovn-common 2.6.0-0ubuntu2~cloud0
amd64 OVN common components
ii ovn-host 2.6.0-0ubuntu2~cloud0
amd64 OVN host components
ii python-networking-ovn 1.0.1.dev4.201610261100.xenial-0ubuntu1
all OpenStack virtual network service - OVN driver
On the compute node:
ii ovn-common 2.6.0-0ubuntu2~cloud0
amd64 OVN common components
ii ovn-host 2.6.0-0ubuntu2~cloud0
amd64 OVN host components
If I create a network in Openstack I can see it in the norhd.
ovn-nbctl show
switch 5cd02e8c-aa16-4246-932e-c1455958daa6
(neutron-83a25bd6-494b-4d9d-ba74-e824a8efb826)
And I can see my compute nodes
ovn-sbctl show
Chassis "4a191104-a3b6-4bde-82ee-1a09ea1b9f17"
hostname: "compute03"
Encap vxlan
ip: "172.16.44.130"
options: {csum="true"}
Encap geneve
ip: "172.16.44.130"
options: {csum="true"}
Chassis "b0623e67-a2cf-4802-9343-807383e3eb94"
hostname: "compute01"
Encap geneve
ip: "172.16.44.17"
options: {csum="true"}
Encap vxlan
ip: "172.16.44.17"
options: {csum="true“}
But if I try to start a VM I get an error in the neutron-server log, could you
please advise me
where my mistake is?
Best regards,
martin
