In my servers now 16g memory. Until such time as did restrictions dom0_mem = 512M and less, the amount of memory capacity increased. After a 512 MB limit - I have a situation where the physical memory is occupied, and completely empty swap. In this balooning - I do not cut off. Basic postulate stable operation - Dom0 should have a minimum of software, and most importantly do not use the internet through virbr0. For distribution network is used as a gateway DomU. And bridges are created manually at boot time.

As a result of lessons learned years ago, I keep dom0 small (<2 GB), and only stubdom-based HVM and straight PV domains are used. xend is not used to manage networking.

To clarify, a machine is still running, and partially usable. It has mysterious memory usage (~1.5 GB of it) that does not show in "top" or "slabinfo", and I am trying to determine what's consuming it. This will in turn hopefully tell me more about how to avoid the situation in the future.
