Hi .. I've made a step by step domU creation .. maybe it would help # cat domU_create_steps.t2t Step by step domU creation 1) Create a directory to put your VMs # mkdir -p /xen/domains/dom1 2) Create a disk and a swap image # dd if=/dev/zero of=/xen/domains/dom1/diskimage.img bs=1024k count=5000
# dd if=/dev/zero of=/xen/domains/dom1/swapimage.img bs=1024k count=512 3) Create a file system to the images # mkfs.ext3 /xen/domains/dom1/diskimage.img # mkswap /xen/domains/dom1/swapimage.img
4) Test if it mounts # mount -o loop /xen/domains/dom1/diskimage.img /mnt/tmp 5) Download a new OS onto virtual disk. In a debian-like system it is possible to use debootstrap(apt-get it).
# debootstrap --arch i386 lenny /mnt/tmp http://ftp.debian.org/debian # debootstrap --arch i386 lucid /mnt/tmp http://archive.ubuntu.com/ubuntu/
6) Some configs # vim /mnt/etc/network/interfaces #To use Specific IP address - edit the /mnt/etc/network/interfaces manually. #To use DHCP, edit and include the following:
# The loopback network interface auto lo iface lo inet loopback # The primary network interface auto eth0 iface eth0 inet dhcp # cp -a /lib/modules/2.6.32.25 /mnt/tmp/lib/modules #UNINSTALL NETWORK MANAGER and AVAHI # apt-get remove network-manager avahi-daemon # vim /mnt/tmp/etc/fstab proc /proc proc defaults 0 0 /dev/sda1 / ext3 defaults,errors=remount-ro 0 1 /dev/sda2 none swap sw 0 0
#create a bridge to eth0 /etc/xen/scripts/network-bridge start netdev=eth0 7) Create domU config # vim /etc/xen/dom1 kernel = "/boot/vmlinuz-2.6.32.25" #CHANGE IT TO YOUR VMLINUZ
ramdisk = "/boot/initrd.img-2.6.32.25" #CHANGE IT TO YOUR INITRD memory = 512 name = "dom1" vif = ['bridge=xenbr0'] disk = ['file:/xen/domains/dom1/diskimage.img,xvda1,w','file:/xen/domains/dom1/swapimage.img,xvda2,w']
#DHCP - remove the ip, gateway and netmask lines, and include:# dhcp = "dhcp" #ip = "ip add" #gateway = "ip add" #netmask = "255.255.0.0"
dhcp = "dhcp" root = "/dev/xvda1 ro" extra = '4' 8) Link in the config file so that the Virtal Machine starts on Bootup of Dom0
# ln -s /etc/xen/dom1 /etc/xen/auto/dom1 9) Start up the VM :-) # xm create dom1 -c
