Libvirt: one NIC, multiple VM, all with Bridged mode

  • 772

I have a question, is it possible to add one host NIC to multiple Virtual machines in libvirt with both of them using it as bridged mode. I've ran out of NIC-s and I still have 2 VM-s who need bridged connection to the network. That is why I was thinking, if it is possible. I can't really experiment with it in my current environment, but I'm a fast learner. :) Please, make me smarter!

    Yes, with KVM I have several virtual machines all running on the same bridged adapter from a single NIC port. They are just all allocated the same bridge device in their configs.
