Connecting guests in a data center through a VPC?

How are VPCs creating on for example AWS? I’m building something similar where I need to connect VPS’s in a data center to each other where some VPS’s need public IPs and some need connectivity to the internet through NAT.

The KVM VPS’s currently are behind a virtual bridge created by Libvirt, but this doesn’t work when the VPS’s are on different hosts and need connectivity between each other. I also don’t believe I can assign a public IP using this methodology.

What I'm struggling with is how I can bridge the guests on the different hosts, would you need something like BGP to route between all guests? If I can get there I believe I can just set-up separate network interfaces for each VPC.

Any advice on how to progress?
