VMware: nova-network creates a port group only on one ESXi in cluster in case with VlanManager

[Ilya Bumarskov]

In case with VlanManager nova-compute creates a appropriate port group (vSwitch) only on one ESXi in cluster. Thus all instances are created only on one ESXi host in cluster.

Openstack Release: Kilo on Ubuntu 14.04

Steps to reproduce:

1. Deploy Fuel 7.0
2. Create env with vcenter support
3. Set Nova VlanManager
4. Add a controller node
5. Configure VMware settings (At least two ESXi hosts should be in cluster)
6. Deploy enviroment
7. Login to Horizon and create a bunch of instances using vcenter availability zone
8. Verify ESXi network settings using vCenter

Observed behavior:

Appropriate port group (br103 in my case) was added only on one ESXi in cluster. All VMs were created only on one ESXi.

Workaround:
We can manually add appropriate port groups on other ESXi in cluster. In such case all new created VMs will be distributed across all ESXi in cluster.

I guess I always assumed most people running the vcenter driver are also running with neutron.

[Matt Riedemann (mriedem)]

I guess both nova-network and neutron are officially supported:

http://docs.openstack.org/kilo/config-reference/content/vmware.html#VMware_networking

But I'd think the neutron vmware plugin would work best:

[Matt Riedemann (mriedem)]

Per this doc:

http://docs.openstack.org/kilo/config-reference/content/vmware.html#VMware_networking

"The nova-network service with the VlanManager. Set the vlan_interface configuration option to match the ESX host interface that handles VLAN-tagged VM traffic."

What is your value for the "vlan_interface" config option in nova.conf? Maybe you have a configuration issue here.
