Thema Virtualisierung
mini-howto.mkd
Kernel Virtual Machine - KVM
The HOWTO describes KVM setup on Debian Lenny.
Checking System Capability
egrep '(vmx|svm)' --color=always /proc/cpuinfo
Installation
As root:
# aptitude update
# aptitude install kvm libvirt-bin virtinst
# aptitude install bridge-utils
# aptitude install virt-manager
Configuration as non previledged User
As root
adduser ckuelker libvirt
exit
#login again
Test Configuration
As normal user:
virsh -c qemu:///system list
Configuring the Network
Using NAT
Save in a file named virbr0
a file named virbr0
<network>
<name>default</name>
<bridge name="virbr0" />
<forward mode="nat"/>
<ip address="192.168.122.1" netmask="255.255.255.0">
<dhcp>
<range start="192.168.122.2" end="192.168.122.254" />
</dhcp>
</ip>
</network>
As root
# virsh net-create virbr0
Network default created from virbr0
Add this to /etc/network/interfaces
/etc/network/interfaces
auto br0
iface br0 inet static
address 192.168.0.100
network 192.168.0.0
netmask 255.255.255.0
broadcast 192.168.0.255
gateway 192.168.0.1
bridge_ports eth0
bridge_fd 9
bridge_hello 2
bridge_maxage 12
bridge_stp off
Then as root:
/etc/init.d/networking restart
# ifconfig
br0 Link encap:Ethernet HWaddr c8:0a:a9:93:3b:58

Test the outsite network
ping www.cipux.org
Create a virtual Machine
mkdir kvm
mkdir kvm/iso
mkdir kvm/vm01
Download an installer CD
cd kvm/iso
wget http://cdimage.debian.org/debian-cd/5.0.6/i386/iso-cd/debian-506-i386-netinst.iso
Create the Machine with NAT network
virt-install --connect qemu:///system -n vm01 -r 512 --vcpus=2 -f ~/kvm/vm01/vm01.qcow2 -s 12 -c ~/kvm/iso/debian-506-i386-netinst.iso --vnc --noautoconsole --os-type linux --os-variant debianLenny --accelerate --network=network:default --hvm
Output
Starting install...
Creating domain... 0 B 00:00
Domain installation still in progress. You can reconnect to
the console to complete the installation process.
Test if it is running
virsh -c qemu:///system list
Id Name State
----------------------------------
1 vm01 running
Connect to your virtual machine
virt-manager
Shutdown
virsh -c qemu:///system shutdown vm01
