[ANNOUNCE] Native Linux KVM tool v2

[Pekka Enberg <penberg@kernel.org>]

Hi all,

We’re proud to announce the second version of the Native Linux KVM tool! We’re
now officially aiming for merging to mainline in 3.1.

Highlights:

- Experimental GUI support using SDL and VNC

- SMP support. tools/kvm/ now has a highly scalable, largely lockless driver
  interface and the individual drivers are using finegrained locks.

- TAP-based virtio networking

- Fast QCOW2 image read-write support beating Qemu in fio benchmarks. See the
  following URL for test result details: https://gist.github.com/1026888

- Virtio-9p support for host filesystem access in guests

- Virtio Random Number Generator

- Host block devices as in-memory copy-on-write guest images on 64-bit hosts

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 remote add kvm-tool git://github.com/penberg/linux-kvm.git
  git remote update
  git checkout -b kvm-tool/master kvm-tool

2. Compile the tool:

  cd tools/kvm && make

3. Download a raw userspace image:

  Minimal:

  wget http://wiki.qemu.org/download/linux-0.2.img.bz2 && bunzip2 linux-0.2.img.bz2

  Debian Squeeze QCOW2 image:

  wget http://people.debian.org/~aurel32/qemu/i386/debian_squeeze_i386_standard.qcow2

4. Build a kernel with the following options:

  CONFIG_VIRTIO_BLK=y
  CONFIG_VIRTIO_NET=y
  CONFIG_VIRTIO_CONSOLE=y
  CONFIG_SERIAL_8250_CONSOLE=y
  CONFIG_HW_RANDOM_VIRTIO=y
  CONFIG_FB_VESA=y

Note: also make sure you have CONFIG_EXT2_FS or CONFIG_EXT4_FS if you use the
above images.

5. And finally, launch the hypervisor:

  ./kvm run -d linux-0.2.img

or

  ./kvm run -d debian_squeeze_i386_standard.qcow2

or

    sudo ./kvm run -d linux-0.2.img -n virtio
