Thanks for the reply,
So, it *should* be possible to pull in public network(s) over flat/vlan to the VMs WITHOUT NAT, while still using GRE for private networking (two NIC per VM... one public with no NAT, the other private via GRE)? I guess I'm trying to see if this is even possible - I think it should be, but XenServer is making this more complicated and there are no decent ML2-based XenServer examples out there. I'm still not sure how to expose a trunk port to a guest to use VLAN networking on the network guest... ~Randy On 06/10/2014 1:32 pm, Martinx - ジェームズ wrote: > Hello Randy, > > Just for the record, I'm using Flat Networks (very similar with VLAN Provider > Networks), with a working Metadata connectivity...
