Dear All,
I am trying to integrate Openstack + vCenter + Neutron + VMware dvSwitch
ML2 Mechanism driver.
I deployed a two node openstack environment (controller + compute with KVM)
with Neutron VLAN + KVM using fuel 5.1. Again I installed nova-compute
using yum in controller node and configured nova-compute in controller to
point vCenter. I am also using Neutron VLAN with VMware dvSwitch ML2
Mechanism driver. My vCenter is properly configured as suggested by the
doc:
https://www.mirantis.com/blog/managing-vmware-vcenter-resources-mirantis-openstack-5-0-part-1-create-vsphere-cluster/
I am able to create network from Horizon and I can see the same network
created in vCenter. When I try to create a VM I am getting the below error
in Horizon.
Error: Failed to launch instance "test-01": Please try again later [Error:
No valid host was found. ].
Here is the error message from Instance Overview tab:

I guess I am missing some thing.
It looks like my issue is similar to this :
https://ask.openstack.org/en/question/43594/vmware-neutron-bridging-problem/
I have configured br100 with VLAN ID 103 in vCenter. But I don't have br100
in my controller node. Not sure how to create it in my controller.
*NOTE :* I have another openstack environment which I deployed as vCenter
Environment using Fuel 5.1 and manually installed/configured Neutron +
VMware dvSwitch ML2 Mechanism driver. It works fine with same vCenter.
Any help?
I happy to provide more info if required.
