Xen Installation in debian etch

Install Xen first

#apt-get update #apt-get install xen-hypervisor-3.0.3-1-i386 xen-utils-3.0.3-1 #apt-get install linux-image-2.6.18-4-xen-686
give the version no according to you deb repository. edit /etc/xen/xend-config.sxp ------------------------------ uncomment this two line
(network-script network-bridge) (vif-script vif-bridge)
Install tools for xen
#apt-get install bridge-utils iproute sysfsutils libc6-xen xen-tools
Create a directory
#mkdir /home/xen
edit /etc/xen-tools/xen-tools.conf here is my sample config file (Here I am showing only uncomment part)
dir = /home/xen debootstrap = 1 # Disk and Sizing options. ## # size = 1Gb # Disk image size. memory = 128Mb # Memory size swap = 128Mb # Swap size # noswap = 1 # Don't use swap at all for the new system. fs = ext3 # use the EXT3 filesystem for the disk image. dist = etch # Default distribution to install. image = full # Specify sparse vs. full disk images. ## # Networking setup values. ## # # Uncomment and adjust these network settings if you wish to give your # new instances static IP addresses. # gateway = netmask = # # Uncomment this if you wish the images to use DHCP # # dhcp = 1 # Uncomment the following line if you wish to interactively setup # a new root password for images. # passwd = 1 # Default kernel and ramdisk to use for the virtual servers # kernel = /boot/vmlinuz-2.6.18-4-xen-686 initrd = /boot/initrd.img-2.6.18-4-xen-686 # The default mirror for debootstrap which can be used to install # Debian Sid, Sarge, and Etch. # mirror = http://ftp.debian.org/debian/
To create an image (here I am showing with debootstraping)
#xen-create-image --hostname=test --ip= --passwd
it will ask for the root passwd after finish the debootstrap. edit /etc/xen/test.cfg check the kernel version is correct for your system
kernel = '/boot/vmlinuz-2.6.18-4-xen-686' ramdisk = '/boot/initrd.img-2.6.18-4-xen-686'
xen-tools generate the disk sda for me. Later I change it to hda
root = '/dev/hda1 ro' disk = [ 'file:/home/xen/domains/test/disk.img,hda1,w', 'file:/home/xen/domains/test/swap.img,hda2,w' ]
check you ip
if = [ 'ip=' ]
To start the vm
#xm create test.cfg -c
it will start to boot (simple output) -------------------------------------

Note: Change your kernel path and disk config according to your system. First time I tried with image = sparse in /etc/xen-tools/xen-tools.conf but it did not work for me. Later I give image = full. for more doc: http://wiki.debian.org/Xen http://www.debian-administration.org/articles/396 http://www.howtoforge.com/perfect_setup_xen3_debian https://help.ubuntu.com/community/XenVirtualMachine/XenOnUbuntuEdgy
