Hi, these Xen related pages are an attempt to use SME Server as Xen host and as a Xen guest.
For more information on Xen see

- UPDATE july 10th, 2006 Since RedHat is planning to fully incorporate Xen into the yet to be release RHE 5, and CentOs 5 will probably contain the same code, these is no use in trying to reinvent the wheel with the below effort. It's better to sit and wait ;-)
SIMPLE description:
Xen is a Linux based OS that has specific capabilities of creating Virtual Machines. This means that when 'Xen-SME Server' boots it is possible to install more Linux distributions e.g. SME Server, Fedora, Debian etc. (Windows is on Xen's roadpath). All installed Virual Machines (Domains) will have acces to (almost) all server resources, connections and devices as if each Virtual machine is a physical server, have their own harddisk space, memory space completely secured from other Virtual Machines. The overhead of Xen for doing this is typacally 2-8% meaning it is VERY fast.
Wouldn't it be interesting to have a Xen-SME Server with a server manager that can do:
- Create new VM
- Select OS from drop down list
- Select partition (selection build from available resources)
- Enter kernel parameters (maybe choose default set per OS)
- Select wether this VM should start at host boot time or not
- Other fine tuning radio buttons
- Create
The listing of Virtual Machines could have options like reboot, shutdown, start.
Dreaming is fun! :-)
Now for SME Server to be a Xen host and/or as a guest (Virtual Machine) there are steps needed. The following pages are happy to catch your thoughts, hints, tips, scripts, how-to's and RPM's ;-)
Thanks for your input!
