TL;DR it wont work with the ovs agent but "should" work with linux bridge. see full message below for details. regards sean.
the linux bridge agent supports the vlan_transparent option only when createing networks with an l3 segmentation type e.g. vxlan,gre... ovs using the neutron l2 agnet does not supprot vlan_transparent netwroks because of how that agent use vlans for tenant isolation on the br-int. it is possible to use achive vlan transparancy with ovs usign an sdn controller such as odl or ovn but that was not what you asked in your question so i wont expand on that futher. if you deploy openstack with linux bridge networking and then create a tenant network of type vxlan with vlan_transparancy set to true and your tenants generate QinQ traffic with an mtu reduced so that it will fix within the vxlan tunnel unfragmented then yes it should be possibly however you may need to disable port_security/security groups on the port as im not sure if the ip tables firewall driver will correctly handel this case. an alternive to disabling security groups would be to add an explicit rule that matched on the etehrnet type and allowed QinQ traffic on ingress and egress from the vm. as far as i am aware this is not tested in the gate so while it should work the lack of documentation and test coverage means you will likely be one of the first to test it if you choose to do so and it may fail for many reasons.
