Subject: [ANNOUNCE] Native Linux KVM tool v2

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

This release was brought to you by the following people:
