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.
