Even though binding:vif_type=hyperv and status=ACTIVE, still IP is not assigned to the instance by DHCP.External and private are the 2 vswitches created on the HyperV compute node and are configured in neutron_hyperv_agent.conf.Any suggestions please,based on above conf files

Hi,neutron net-show $NETWORK_ID has provider:network_type as vlan. Initially "neutron agent-list" result showed DHCP agent, HyperV agent and Open vSwitch agent as alive.I dont know when the status is changed to XXX.

Hi Claudiu,

Thank you for the reply. I made the modifications suggested by you. After creating bridges and adding ports to it.

Result of ovs-vsctl show:

I booted new instance. It is in active state but Ip is not assigned to it.

We are using Openstack Icehouse release.

Please suggest any solution.

I have an openstack controller installed using COI in which all openstack services are running except nova-compute. Used Cloudbase openstack compute installer for setting up hyper-v compute node in which nova-compute is running. Able to boot the instance but dhcp agent is unable to assign ip to the instance.

/etc/neutron/neutron.conf has: coreplugin = neutron.plugins.hyperv.hypervneutron_plugin.HyperVNeutronPlugin

/etc/neutron/dhcpagent.ini interfacedriver =neutron.agent.linux.interface.OVSInterfaceDriver

There seems to be no bridges concept in hyper-v, we have vswitch and portgroup networking stack. Is there any interface driver which is compatible with hyper-v plugin? Anyone please suggest where can I find detailed networking guide for hyper-v plugin.

Any help will be appreciated.
