This is the first release of block and network drivers for Linux guests running on a kvm host. The drivers are intended for guest kernels 2.6.18-2.6.24. Newer kernels include the drivers; older kernels may not work. kvm-61 or later is needed in the host.
Network throughput is around 1 Gbit/sec; latency is currently a less than stellar 0.3 msec. Both these figures will be improved in the future. The drivers are available from the download page of the kvm website, below. To use, download the drivers into the guest (using one of the emulated network cards), unpack the package, and type make sudo make install You will need the kernel development package installed. To use the drivers, reboot with '-net nic,model=virtio' instead of the usual setting, and 'modprobe virtio_net' to load the module. Similarly use '-drive ...,if=virtio' for the block device, and the corresponding virtio_blk.ko. Initial release: - virtio pci driver (Anthony Liguori, Rusty Russell, Dor Laor) - virtio network driver (Anthony Liguori, Rusty Russell, Dor Laor) - virtio block driver (Anthony Liguori, Rusty Russell, Dor Laor) - backports to Linux 2.6.18-2.6.24 (Anthony Liguori, Rusty Russell, Dor Laor) http://kvm.qumranet.com/ -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
