[Openstack] [Neutron][HyperV]HyperV Networking Problem

Hi Ray,

Some Windows network adapter drivers disable VLAN access by default.

Here's Powershell script that will apply the adapter's proper configuration:

In case the script reports that one of morte adapters have been reconfigured, you'll need to reboot or restart the corresponding adapters.

If you prefer to perform the steps manually, open the following registry key:


Look in all the child keys xxxx, e.g. 0001, 0002 etc for a value “VLanFiltering”. Make sure that if present it’s set to 0.
In case of changes, reboot the server or restart the corresponding adapters.

Please let me know if this works for you.

Note: the error that you are reporting:
 ERROR [quantum.openstack.common.rpc.amqp] Exception during message handling
has been fixed with https://review.openstack.org/#/c/46989/

Dear all,
I am trying to test HyperV with OpenStack in Quantum VLAN model. But seems the network can't be reachable.

I use devstack to install my controller, by default, I use stable/grizzly branch. Here's my localrc file:
disable_service n-net
enable_service q-svc
enable_service quantum
enable_service q-dhcp
enable_service q-l3




Then I create a new file /etc/quantum/plugins/hyperv/hyperv_quantum_plugin.ini
sql_connection = mysql://root:admin@localhost/hyperv_quantum?charset=utf8

tenant_network_type = vlan
network_vlan_ranges = default:1000:2999

firewall_driver = quantum.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

To avoid security groups problem, I also update nova.conf:
firewall_driver = nova.virt.libvirt.firewall.IptablesFirewallDriver

The I restart nova-api service and modify quantum server command line, using:
cd /opt/stack/neutron && python /opt/stack/neutron/bin/quantum-server --config-file /etc/quantum/quantum.conf --confifile /etc/quantum/plugins/hyperv/hyperv_quantum_plugin.ini

Everything seems ok except these logs:
2013-10-10 18:09:02    ERROR [quantum.openstack.common.rpc.amqp] Exception during message handling
Traceback (most recent call last):
  File "/opt/stack/neutron/quantum/openstack/common/rpc/amqp.py", line 430, in _process_data
    rval = self.proxy.dispatch(ctxt, version, method, **args)
  File "/opt/stack/neutron/quantum/common/rpc.py", line 43, in dispatch
    quantum_ctxt, version, method, **kwargs)
  File "/opt/stack/neutron/quantum/openstack/common/rpc/dispatcher.py", line 136, in dispatch
    raise AttributeError("No such RPC function '%s'" % method)
AttributeError: No such RPC function 'report_state'

But I don't think this will impact me, I remember I saw this bug on the lanchpad, I follow the most introduction of the document:

After I finished all the steps, I tried to create a new instance using a private network. I got my VM(Ubuntu) ready but without network connection. As the pictures shown in the document above, I also got an external NIC with VLAN id 1001 for the new VM.

Seems DHCP can not assign ip for the new VM.

I try to tcpdump on my controller of my new VM's mac address, and I got: > [udp sum ok] BOOTP/DHCP, Request from fa:16:3e:25:7a:73 (oui Unknown), length 300, xid 0x880a075d, Flags [none] (0x0000)
 Client-Ethernet-Address fa:16:3e:25:7a:73 (oui Unknown)
 source link-address option (1), length 8 (1): fa:16:3e:25:7a:73

But in my syslog of controller, I can't see any dhcp related logs.

My questions is:
1. In my local network we have 3 VLANs(id is 1, 2, 3), do I need to set new VLANs based my configuration for quantum(1000:1999) on my hardware?
2. Do I need to setup any trunk port in my connection ports?
3. Can I use any other network type like Flatdhcp, even or nova-network for simple?


Best Regards
