Is needed to use virtio drivers in new Linux guests


I have one doubt about the virtio Paravirtualized drivers for kvm/Linux.
In windows you must install them to improve network/block/balloon devices.
But in recent distros up to 2.6.25 kernels like Fedora, Ubuntu and Debian, is needed to activate some modules? or are they configured into the kernel by default?.
Is needed to do something to use this drivers?.

Thank you.



I actually have the exact same question as you as I’ve looked everywhere and can’t really find any documentation stating such. Did you ever find your answer elsewhere as I can tell you didn’t have it answered here. I’d really appreciate anyone’s insight on this. Thanks!
