oh, have fun.
to create the parent server
install the freegeek-xen-server which includes some custom hooks for xen at freegeek.
apt-get install freegeek-xen-server
edit /etc/xen-tools/xen-tools.conf:
kernel = /boot/vmlinuz-xen initrd = /boot/initrd.img-xen debootstrap = 1 lvm = vg dist = etch passwd = 1 mirror = http://apt.freegeek.org:9999/debian/
modify /etc/xen/xend-config.sxp:
(network-script freegeek-network-script)
- Controlling the amount of memory dom0 uses
- In /boot/grub/menu.lst add to the line # xenhopt=dom0_mem=256M then run update-grub
to create an instance on the parent server
Create new xen instances with:
xen-create-image --hostname SERVERNAME --ip 192.168.?.? --netmask 255.255.255.0 --gateway 192.168.?.1
Make sure SERVERNAME and the chosen ip address don't exist already.
It will ask for a root password. Have one prepared and ready to go.
Your configuration file will be in:
/etc/xen/NAME.cfg
Check to see that it is there.
To have it start automatically:
ln -s /etc/xen/NAME.cfg /etc/xen/auto/
To start the xen instance:
xm create NAME.cfg
To list the running xen instances and how much resources they're using:
xm list
To get to a login screen on the vm, either ssh in, or:
xm console NAME
To get out of the instance, the secret keystroke is Ctrl-].
log into the xen instance (either with ssh or xm console), and ensure the freegeek-xen-instance package is installed:
apt-get install freegeek-xen-instance
