PCI passthrough strategy in Docker or oVirt
We have to deploy a test system where a Docker container or a VM (oVirt 3.5) shares up to 4x 10GB network cards with other containers/VMs.
So far we are using just oVirt for this purpose but we would like to shift to a Dockerized system to save some resources on the machines.
Does anybody have some experience or suggestion?

Docker containers are really just processes; it can run them each in a separate network namespace (the default) or let them use the host’s network directly (
If running in a separate network namespace then they won’t have any access to the host’s network cards; in the default config (
--net=bridge) they are NAT networked via a Linux bridge, so if that matches your requirements, you’re away.
