Depends what your goal is, if you want to run a cluster with shared
memory between system
Thank you, for all your answers!
What about the other question? Can clustering help in completing this
task? I thought cluster nodes are sharing RAM on default ( obviously I
was wrong).

Not with the current Xen I don't believe. I think some bleeding edge
versions of KVM support memory sharing and/or ballooning
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
