Agraf:

= Introduction =

We will reserve some time for people to get together and discuss
strategic decisions as well as other topics that are best solved within
smaller groups. This time can also be used for hands-on hacking
sessions.

If you are interested in organizing such a group time event, please add
it to the list *before* KVM Forum, so people have time to organize which
one they will attend.

All of these sessions will get the chance to quickly talk about results
they managed to achieve during their time in a quick "results" session.

Code

Agraf: update kvm-kmod url

=Code=

[[Category:Architechture]]

== kernel git tree ==

The kvm kernel code is available through a git tree (like the kernel itself). To create a repository using git, type

git clone git://git.kernel.org/pub/scm/virt/kvm/kvm.git

Alternatively, it is also accessible through the kernel.org gitweb interface:
[http://git.kernel.org/?p=virt/kvm/kvm.git;a=summary]

For subsequent upgrades use the command

git pull

in the git working directory.

== kernel git workflow ==

See [[Kvm-Git-Workflow]]

== userspace git tree ==

The kvm userspace code (libkvm and qemu) is available through a git tree. To create a repository using git, type

git clone git://git.kernel.org/pub/scm/virt/kvm/qemu-kvm.git

Alternatively, it is also accessible through the kernel.org gitweb interface:
[http://git.kernel.org/?p=virt/kvm/qemu-kvm.git;a=summary]

'''If you want to contribute code''', please [http://wiki.qemu.org/Contribute/StartHere develop against qemu.git] and submit patches to qemu-devel@nongnu.org. The qemu-kvm.git tree regularly gets changes from qemu.git and patches against qemu-kvm.git should be minimized.

== building an external module with older kernels ==

'''This only works for the x86 architecture.'''

1. If you wish to use a distribution kernel (or just some random kernel you like) with kvm,
you can use the external module kit. You will need the kvm-kmod repository:

git clone git://git.kiszka.org/kvm-kmod.git
cd kvm-kmod
git submodule update --init
./configure [--kerneldir=/path/to/kernel/dir]
make sync
make

=== Tip about building against Red Hat Enterprise Linux kernels ===

<code>kvm-userspace/kernel</code> has some compat code to allow it to compile against older kernels, and also some code specific to features that are normally not present on older kernels but are present on RHEL kernels.

So, when building against a RHEL kernel tree, check if the <code>RHEL_*</code> macros at <code>${kerneldir}/include/linux/version.h</code> are defined correctly, corresponding to the RHEL version where the kernel source comes from. If those macros aren't defined correctly, the compat code that allows compilation against RHEL kernels will break and you will get build errors.

== release tags ==

kvm stable releases (based off of Qemu's stable branch) are tagged with <code>kvm-qemu-0.NN.N</code> where ''N'' equates to the upstream Qemu branch versions. Note that kvm has them tagged not branched.

kvm development releases are tagged with <code>kvm-nn</code> where ''nn'' is the release number.

== Binary Packages ==

=== CentOS / RHEL ===

Unofficial packages of latest releases can be found at:
<code>http://www.lfarkas.org/linux/packages/centos/5/</code>

=== Debian ===

For Debian Lenny, please use packages from backports.debian.org - for <em>both</em> qemu-kvm and kernel (at least 2.6.32). It is important to use more recent kernel - 2.6.26 does not work well with kvm.

Note that package "kvm" has been renamed to "qemu-kvm" in Squeeze and in Lenny backports (and kvm is now transitional package that installs qemu-kvm automatically).

Debian Squeeze will have qemu-kvm based on 0.12, available in standard repositories.

Experimental 0.13 packages are available at
<code>http://www.corpit.ru/debian/tls/kvm/0.13/</code> , pending upload to debian -experimental.

== nightly snapshots ==

Nightly snapshots, for those who are uncomfortable with git, are [http://people.qumranet.com/avi/snapshots available]. When reporting a problem with a snapshot, please quote the snapshot name (which includes the date) and the contents of the SOURCES file in the snapshot tarball.

Networking

2010-04-08T15:01:44Z

Agraf:

= Setting guest network =

Guest (VM) networking in kvm is the same as in qemu, so it is possible to refer to other documentations about networking for qemu. This page will try to explain how to configure the most frequent types of network needed.

== User Networking ==

'''Use case:'''
* You want a simple way for your virtual machine to access to the host, to the internet or to resources available on your local network.
* You don't need to access your guest from the network or from another guest.
* You are ready to take a huge performance hit.
* Warning: User networking does not support a number of networking features like ICMP. Certain applications (like ping) may not function properly.

'''Prerequisites:'''
* You need kvm up and running
* If you don't want to run as root, the user you want to use needs to have rw access to /dev/kvm
* If you want to be able to access the internet or a local network, your host system must be able to access the internet or the local network

'''Solution:'''
* simply run your guest with "-net nic -net user", e-g:
qemu-system-x86_64 -hda /path/to/hda.img -net nic -net user

'''Notes:'''
* The IP address can be automatically assigned to the guest thanks to the DHCP service integrated in QEMU
* If you run multiple guests on the host, you don't need to specify a different MAC address for each guest
* You can still access one specific port on the guest using the "hostfwd" option.This means e.g. if you want to transport a file with scp from host to guest, start the guest with "-net nic -net user,hostfwd=tcp::5555-:22". Now you are forwarding the host port 5555 to the guest port 22. After starting up the guest, you can transport a file with e.g. "scp -P 5555 file.txt root@localhost:/tmp" from host to guest. Or you can also use other address of the host to connect to.

== private virtual bridge ==

'''Use case:'''
* You want to set up a private network between 2 or more virtual machines. This network won't be seen from the other virtual machines nor from the real network.

'''Prerequisites:'''
* You need kvm up and running
* If you don't want to run as root, the user you want to use needs to have rw access to /dev/kvm
* You need the following commands installed on your system, and if you don't want to run as root, the user you want to use needs to be able to sudo the following command:
/sbin/ip
/usr/sbin/brctl
/usr/sbin/tunctl

'''Solution:'''

* You need to create a bridge, e-g:
sudo /usr/sbin/brctl addbr br0

* You need a qemu-ifup script containing the following:
#!/bin/sh
set -x

switch=br0

if [ -n "$1" ];then
/usr/bin/sudo /usr/sbin/tunctl -u `whoami` -t $1
/usr/bin/sudo /sbin/ip link set $1 up
sleep 0.5s
/usr/bin/sudo /usr/sbin/brctl addif $switch $1
exit 0
else
echo "Error: no interface specified"

* Each guest on the private virtual network must have a different MAC address

== public bridge ==

'''WARNING:''' The here shown method, will not work with most(all?) wireless drivers, as these do not support bridging.

'''Use case:'''

* You want to assign an IP address to your virtual machines and make them accessible from your local network
* You also want performance out of your virtual machine.

'''Prerequisites:'''
* You need kvm up and running
* If you don't want to run as root, the user you want to use needs to have rw access to /dev/kvm
* You need the following commands installed on your system, and if you don't want to run as root, the user you want to use needs to be able to sudo the following command:
/sbin/ip
/usr/sbin/brctl
/usr/sbin/tunctl

* Your host system must be able to access the internet or the local network

'''Solution 1: using distro sysconfig script'''

|
* Edit /etc/sysconfig/network-scripts/ifcfg-eth0
** comment out BOOTPROTO
** Add BRIDGE=br0
* Create /etc/sysconfig/network-scripts/ifcfg-br0
** The content should be:
DEVICE=br0
BOOTPROTO=dhcp
ONBOOT=yes
TYPE=Bridge
|
/etc/network/interfaces
auto <strike>eth0</strike> br0

iface br0 inet dhcp
bridge_ports eth0
bridge_stp off
bridge_maxwait 0
bridge_fd 0

|
* Start YaST
* Go to Network Configuration
* Add new device -> Bridge
* Tick your existing network device
* done
|}

* /etc/init.d/networking restart
* The bridge br0 should get the ip address (either static/dhcp) while the physical eth0 is left without ip address.

'''Solution 2: manual'''

* You need to create a bridge, e-g:
sudo /usr/sbin/brctl addbr br0

* Add one of your physical interface to the bridge, e-g for eth0:
sudo /usr/sbin/brctl addif br0 eth0

* You need a qemu-ifup script containing the following:

#!/bin/sh
set -x

switch=br0

if [ -n "$1" ];then
/usr/bin/sudo /usr/sbin/tunctl -u `whoami` -t $1
/usr/bin/sudo /sbin/ip link set $1 up
sleep 0.5s
/usr/bin/sudo /usr/sbin/brctl addif $switch $1
exit 0
else
echo "Error: no interface specified"
exit 1
fi

* Generate a MAC address, either manually or using:

#!/bin/sh
# generate a random mac address for the qemu nic
# shell script borrowed from user pheldens @ qemu forum
echo $(echo -n DE:AD:BE:EF ; for i in `seq 1 2` ;
do echo -n `echo ":$RANDOM$RANDOM" | cut -n -c -3` ;done)

* Run each guest with the following, replacing $macaddress with the value from the previous step
qemu-system-x86_64 -hda /path/to/hda.img -net nic,macaddr=$macaddress -net tap

'''Notes:'''
* If you don't want to run as root, the qemu-ifup must be executable by the user you want to use
* You can either create a system-wide qemu-ifup in /etc/qemu-ifup or use another one. In the latter case, run
qemu-system-x86_64 -hda /path/to/hda.img -net nic,macaddr=$macaddress -net tap,script=/path/to/qemu-ifup

* Each guest on the network must have a different MAC address

== iptables/routing ==

you can also connect your guest vm to a tap in your host. then setting iptables rules in your host to become a router + firewall for your vm.

Routing would be done simply by creating the default route on the client to the IP of the host (and allowing IP forwarding) and setting a route to the tap? device of the client on the host.
Test the setup beforehand:
*Hostside: Allow IPv4 forwarding and add route to client (could be put in a script - route has to be added after the client has started):
sysctl -w net.ipv4.ip_forward=1 # allow forwarding of IPv4
route add -host <ip-of-client> dev <tap-device> # add route to the client
*Clientside: Default GW of the client is of course then the host (<ip-of-host> has to be in same subnet as <ip-of-client> ...):
route add default gw <ip-of-host>

== vde ==

another option is using vde (virtual distributed ethernet).

== performance ==

Data on benchmarking results should go in here.

Agraf: Add non-x86 architectures to the list

Information about what cpu supports Hardware virtualization.

==== INTEL: ====

VT-x, shows in /proc/cpuinfo as the vmx flag.

AKA Vanderpool

See Wikipedia's article on x86 virtualization,
for a list of processors that include it.

http://en.wikipedia.org/wiki/X86_virtualization#Intel_Virtualization_Technology_for_x86_.28Intel_VT-x.29

==== AMD: ====

AMD-V, shows in /proc/cpuinfo as the svm flag.

AKA Pacifica

http://en.wikipedia.org/wiki/X86_virtualization#AMD_virtualization_.28AMD-V.29

==== PowerPC: ====

KVM for PowerPC supports selected embedded cores. It also supports all 64-bit server / desktop class CPUs like the G5, POWER4 and above, Cell, 970MP, etc.
