Debian Etch installation

Packages install

INTEL

sudo apt-get install linux-image-2.6.18-6-xen-686 xen-hypervisor-3.0.3-1-i386-pae xen-linux-system-2.6.18-6-xen-686 libc6-xen bridge-utils

AMD

sudo apt-get install linux-image-2.6-xen-amd64 xen-hypervisor-3.0.3-1-amd64 xen-linux-system-2.6.18-5-xen-amd64 libc6-xen bridge-utils

Optional packages:

xen-docs-3.0
xen-shell

Network config

Before the reboot, a small change in /etc/xen/xend-config.sxp should be done.

Replace

with

(network-script 'network-bridge netdev=eth0')

reboot

xen-tools

(optional) to install latests version from project repository add to sources.lists

deb-src http://apt.steve.org.uk/etch etch main non-free contrib

sudo apt-get install xen-tools

xen-tools config

in /etc/xen-tools/xen-tools.conf

lvm = vg0
debootstrap = 1

size   = 10Gb      # Disk image size.
memory = 256Mb    # Memory size
swap   = 256Mb    # Swap size
fs     = ext3     # use the EXT3 filesystem for the disk image.
dist   = etch    # Default distribution to install.
image  = sparse   # Specify sparse vs. full disk images.

dhcp = 1

kernel = /boot/vmlinuz-2.6.18-5-xen-amd64
initrd = /boot/initrd.img-2.6.18-5-xen-amd64

mirror = http://ftp.us.debian.org/debian/

Administration

Create image

xen-create-image --hostname vserver1.mydomain

or use with options

xen-create-image --hostname=vm1.domain.com --size=5Gb --swap=256Mb --ide \
--ip=192.168.0.101 --netmask=255.255.255.0 --gateway=192.168.0.1 --force \
--dir=/vserver --memory=32Mb --arch=i386 --kernel=/boot/vmlinuz-2.6.18-xenU \
--debootstrap --dist=etch --mirror=http://ftp2.de.debian.org/debian/ --passwd

Boot

xm create /etc/xen/vserver1.mydomain.cfg

Console connect

xm console vserver1.mydomain

Other common commands

xm shutdown <name> - Stop a virtual machine.
xm destroy <name> - Stop a virtual machine immediately without shutting it down. It's as if you switch off the power button.
xm list - List all running systems.
xm help - List of all commands.

Common problems

To fix up "4gb seg fixup" errors on sarge and olds domU's

mv /lib/tls /lib/tls.disabled

Error: Device 0 (vif) could not be connected

If you get the following error when trying to create a domU:

Error: Device 0 (vif) could not be connected. Backend device not found.

and your /var/log/xen/xend-debug.log shows something complaining about brctl, like that:

/etc/xen/scripts/network-bridge: line 114: brctl: command not found

it seems that bridge-utils package is not installed in your host, so:

apt-get install bridge-utils
/etc/init.d/xend restart

should solve the problem.
