We discussed the possibility of creating System VMs for LXC. There was concern with the complexity and potential issues involving iptables for the router inside an LXC container. As an intermediate solution we are going to use KVM System VMs inside the LXC Cluster.

Direct Networking

Libvirt supports direct attachment of the guest VM's network to a physical interface. To enable this mode, add the following to agent.properties:

libvirt.vif.driver=com.cloud.hypervisor.kvm.resource.DirectVifDriver
network.direct.source.mode=private/bridge/vepa
network.direct.device=eth0
