[Gllug] Xen - bit of a ramble

[Matthew Cooke]

I'm not going to be any help on the installing front but i have been using 
Xen for a while.

I tried it originally from the xen liveCD which worked very well if you are 
just playing around:
http://www.xensource.com/xen/downloads/

You just pop it in, boot from CD and you can create a few different host 
OS's and log into them remotely on different ips.

I was so impressed I'm actually hosting the site I am currently developing 
on a Xen host (run by www.unixshell.com on a dual opteron). I've actually 
been very impressed with the price/performance of hosted xen.

I have 1 Vm that hosts our main site with 1gig ram dedicated to our VM. The 
hosting servers now have over 8gig ram in total as the latest xen supports 
addressing over this limit. I also have a smaller xen  host running 
monitoring. The site i'm developing is a digg style site for humour so not 
that uptime critical (www.eatmyhamster.com) but i've generally been quite 
impressed with xen.

I used to manage another app on a cluster of around a dozen real servers and 
it's quite nice not to have to worry about hardware failures and in the case 
of abovenet the entire datacenter overheating etc,
