Hi all, Weâre proud to announce the native Linux KVM tool! The goal of this tool is to provide a clean, from-scratch, lightweight KVM host tool implementation that can boot Linux guest images (just a hobby, won't be big and professional like QEMU) with no BIOS dependencies and with only the minimal amount of legacy device emulation. Note that this is a development prototype for the time being: there's no networking support and no graphics support, amongst other missing essentials. It's great as a learning tool if you want to get your feet wet in virtualization land: it's only 5 KLOC of clean C code that can already boot a guest Linux image. Right now it can boot a Linux image and provide you output via a serial console, over the host terminal, i.e. you can use it to boot a guest Linux image in a terminal or over ssh and log into the guest without much guest or host side setup work needed. 1. To try out the tool, clone the git repository: git clone git://github.com/penberg/linux-kvm.git or alternatively, if you already have a kernel source tree: git checkout -b kvm/tool git pull git://github.com/penberg/linux-kvm.git 2. Compile the tool: cd tools/kvm && make 3. Download a raw userspace image: wget http://wiki.qemu.org/download/linux-0.2.img.bz2 && bunzip2 linux-0.2.img.bz2 4. Build a kernel with CONFIG_VIRTIO_BLK=y and CONFIG_SERIAL_8250_CONSOLE=y configuration options. Note: also make sure you have CONFIG_EXT2_FS or CONFIG_EXT4_FS if you use the above image. 5. And finally, launch the hypervisor: ./kvm --image=linux-0.2.img --kernel=../../arch/x86/boot/bzImage The tool has been written by Pekka Enberg, Cyrill Gorcunov, and Asias He. Special thanks to Avi Kivity for his help on KVM internals and Ingo Molnar for all-around support and encouragement!
