Re: VPC virtual router NIC limit
A theoretical change could be to switch from VLAN assigned VIFs to using
the VLAN feature in Linux kernel. That would give interface names like
eth0.100 instead of eth0-6. Would need one NIC for each physical Network
though.
And I do not know if all hypervisors supports trunk ports.

I considered the eth0.100 as virtual as well, but truly virtual is fine :-)

vxlan as isolation in general would be interesting too
+1, for 4.9 release? ;-)

Hoi Erik,
You then don’t need eth interfaces for each tier and create a virtual interface in the openvswitch bridge instead. This has virtually no limit.
Openvswitch also brings features like vxlan connections between routers and such, so could be very interesting.
Regards,
Remi

How would changing to openvswitch change anything in this scenario?

I don't think that would work. Instead, we could change to openvswitch as that makes it way more flexibele. As far as I know there are no plans / is no one working on that right now.
