Hi, all! I have a server with 4 virtual machines ( using xen). Is there a way to make them share RAM? I found out something about balloons, but it didn't distribute RAM dynamically. So I decided that xen can't achieve that. I tried luci and ricci and now all my VMs are in a cluster. But I don't think this actually helped. Can you suggest a software and/or manual or a question which I should ask google for completing this task? All doms/nodes are with Centos 5.3(final). Thanks!
