And I would like to add: Is there a recommendation for /tmp capacity and
swap size for dom0 ?

I am about to setup a production server and I am eager to hear the
list's experiences with regards to how many resources dom0 needs for
running well.

I guess that there is no great need for driver memory in case a domU is
running off physical partitions since the disk access then goes directly
through the hypervisor (?). But what about when dom0 is serving
file-backed vbd's ? Will a 64 MB dom0 behave like a normal file server
with only 64 MB mem ?
