[Users] CPU and Memory sharing

2014-02-04 Thread Jaison peter 
Hi all ,

 I would like to know whether CPU or memory sharing among physical nodes
are possible in ovirt . Suppose I have 3 physical nodes in my cluster with
24GB RAM and 8 cores each . Then one of my client needs a VM with 32GB RAM
and 12 cores , that means vm need resources more than a physical server .
So is that possible in ovirt cluster .?  If it is not directly possible is
they are any  cloning  Load balancing methods like in amzon auto scaling
?

not sharing, but overcommit yes. 
if it really needs more RAM than the host has then it's going to swap…well, you 
may try to use network swap I suppose
performance is not going to be great in any case, obviously.
