KVM

Description

Setting up the Kernel-based Virtual Machine including network configuration and beeing able to create and run new machines as a normal user without requiring root privileges.

Installation

# # emerge kvm

Network configuration

# # /etc/init.d/

# # ln -s net.lo net.br0

# # ln -s net.lo net.tap0

# # rc-update add net.br0 default

# # rc-update add net.tap0 default

# # rc-update add vde default

Add user to the necessary groups

# # usermod -a -G kvm,qemu username

Usage

Generate random MAC adresses

$ # echo -n DE:AD:BE:EF ; for i in `seq 1 2` ; do echo -n `echo ":$RANDOM$RANDOM" | cut -n -c -3` ;done

You can always setup new machines in your home directory, but here we assume we have a separate mount-point/partition which we mount at /mnt/kvm.

$ # mkdir -p /mnt/kvm

Template:Box File

# # chown -R root:kvm /mnt/kvm

# # chmod -R g+w /mnt/kvm

$ # kvm-img create -f qcow2 /mnt/kvm/linux-test.img 15G

$ # vdeq kvm /mnt/kvm/linux-test.img -cdrom /dev/cdrom -soundhw es1370 -usb -m 1024 -k de -smp 1 -vga std -localtime -net nic,vlan=0,macaddr=DE:AD:BE:FF:15:33 -net vde,vlan=0,sock=/var/run/vde.ctl

$ # kvm-img create -f qcow2 /mnt/kvm/windows-test.img 15G

$ # vdeq kvm /mnt/kvm/windows-test.img -cdrom /dev/cdrom -soundhw es1370 -usb -m 1024 -k de -smp 1 -vga std -localtime -net nic,vlan=0,macaddr=DE:AD:BE:EF:14:32 -net vde,vlan=0,sock=/var/run/vde.ctl

Once done installing and after enabling the remote desktop access in Windows you can add the -nographic switch and start the kvm machine via a login script for example.

$ # vdeq kvm /mnt/kvm/windows-test.img -nographic -soundhw es1370 -usb -m 1024 -k de -smp 1 -vga std -localtime -net nic,vlan=0,macaddr=DE:AD:BE:EF:14:32 -net vde,vlan=0,sock=/var/run/vde.ctl

You really want to use an RDP session to connect to your Windows Boxes since the mouse movement is horrible slow and laggy when using the SDL client.
