[Xen-users] How to install an Ubuntu DomU on Ubuntu 10.04 Dom0
Hi, I''m a newbie in VM/Xen. As a first step to do some study/experiment on VM, I want to install Ubutnu (10.04) as DomU on top of Ubutu (10.04) Dom0. I need some direction to stat with: - how to install the DomU image - how to configure the network address I''d be greatly thankful to you for providing some useful link to this end. Thank you in advance. Regards, -shopno _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] How to install an Ubuntu DomU on Ubuntu 10.04 Dom0
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
