Ideally, we'd like to content system ram - so each machine is configured to have 1GB available. This obviously means we need to contend memory .. probably 3:1 (including the requirements of the Dom-0). Is this possible ?
maxmem = 1024
memory = 256
When it comes time to use the VM you care about, use xm mem-set to increase it's memory to 1G (and after you're finished, decrease it back down to 256).

Many thanks for replying.

I see; this isn't possible to do dynamically ?

It requires manual intervention. As someone has previously mentioned, Xen does not support any concept of overcommit.
