In other words, there's no solution for bridged networking? How would routed networking impact the guest performance? The reason I went for bridged was that it was supposed to have the least overheads and here http://www.cyberciti.biz/faq/rhel-linux-kvm-virtualization-bridged-networking-with-libvirt/ said it was required for servers with multiple network cards. Which is the case here because I have 3 NICs, one each for Internet traffic, networked storage and user access. Although, admittedly on hindsight, given the number of users in the company, it probably isn't going to be noticeable I would still like to know what kind of impact would it cause. That is assuming routed networking can work on the server given the NICs in it.
