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?

Re: VPC virtual router NIC limit

[Remi Bergsma]

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.

Re: VPC virtual router NIC limit

[Erik Weber]

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.

RE: VPC virtual router NIC limit

[Davide Pala]

i've setup a new network offert on the VPC but i can't see it when i try to add 
a new network ... i suppose that i've done something wrong but think that the 
VLANs are the correct path

Hi Davide

I know very little about the VPC router, just getting started with CloudStack. 
But have you thought about creating virtual interfaces via vlans?

Kind regards
