Hello list: I'm working on a project that calls for the creation of a firewall in KVM. While adding a 20-interface trunk of virtio adapters to bring in a dual 10GB bond, I've discovered an 8 NIC limit in QEMU. I found the following thread in the list archives detailing a similar problem: http://kerneltrap.org/mailarchive/linux-kvm/2009/1/29/4848304 It includes a patch for the file qemu/net.h to allow 24 NICs: https://bugs.launchpad.net/ubuntu/+source/qemu-kvm";>qemu-kvm/+bug/595873/+attachment/1429544/+files/max_nics.patch In my case I want to attach 29, and have simply changed line 8 to 30 from 24.
I'd guess you'll bump into a pci device number limit (I believe it is 32 at the moment).
This will be the first patch I've ever had to do, and so far my internet search yields results that don't seem to apply. Would someone like to recommend a pertinent tutorial?
