[Openstack] Fwd: Running OVS with VLAN tagged ports inside a ESXi host

Hi, is this feasable to do? I'm trying to run some servers inside of a ESXi
host that uses a OpenvSwitch with VLAN tagged ports. I've tagged the port
group with 4095 in the ESXi host and then inside the VM I do:
ovs-vsctl add-br br-virtual
ovs-vsctl add-port br-virtual eth1
ovs-vsctl add-port br-virtual vlan61 tag=61 -- set Interface vlan61
ifconfig vlan61 172.16.59.X/24
But if I try to get traffic going on the vlan61 interface all I can get
going is L2 traffic, L3 is jammed. And I know there's hosts there that's up
and running because I have 2 physical nodes on the same VLAN using the
method described above and they work perfectly.
Though the funny bit is if I setup the VLAN interface using
vconfig add eth1 61
ifconfig eth1.61 172.16.59.X/24
I can ping other hosts on the VLAN but not when using the OVS method?
I am basically trying to achieve something like RS does with their private
"cloud on cloud" terminology, where you run the cloud services in a virtual
environment rather then in a physical one.
NOTE: the following are still drafts
Basically the original issue was that I would have L3 connectivity issues
between my instances on the compute nodes and the Router / DHCP part
running on the Virtual machine inside the Hypervisor running those services
but L2 worked fine.
Can anyone help me figure this out? I feel that VLANs are maybe
incompatible for my wanted setup and maybe tunneling would be way better?
