Hi Akihiro,

Thanks for the reply.
I was relieved to know this was not a problem only for me.

I agree that it is not valid solution to add a port with "type=internal".
However, I have no idea what to do.

>>>>>>>>>> Hi quantum hackers,
>>>>>>>>>>
>>>>>>>>>> We're pushing a change to devstack to use a new vif-driver for Quantum
>>>>>>>>>> with Open vSwitch (https://review.openstack.org/#/c/11650/).  The
>>>>>>>>>> benefit of this driver is that it is compatible with Nova's security
>>>>>>>>>> group filtering.  This is "a good thing", since it more closely maps
>>>>>>>>>> to how real users will deploy Quantum.
>>>>>>>>>>
>>>>>>>>>> However, this may catch developers by surprise who are suddenly unable
>>>>>>>>>> to ping or SSH to instances because the security groups drop traffic
>>>>>>>>>> by default.
>>>>>>>>>>
>>>>>>>>>> Preferred method of dealing with this is to add the following lines to
>>>>>>>>>> local.sh in your devstack directory, which open up your VMs for ping
>>>>>>>>>> and SSH for the 'demo' user:
>>>>>>>>>>
>>>>>>>>>> nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
>>>>>>>>>> nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
>>>>>>>>>>
>>>>>>>>>> Another work around is to disable nova security groups by adding
>>>>>>>>>> 'LIBVIRT_FIREWALL_DRIVER=nova.virt.firewall.NoopFirewallDriver' to
>>>>>>>>>> your localrc
