Hello all,

I am new to this list and have a couple of questions,
that I did not find any answers in FAQ or docs:

1) I need to configure dom0 memory, but do not know
   how to quantify it. Do I need to put all memory
   to dom0? Mathematically speaking,

   Mem(dom0) > Mem(dom1..domN) or
   Mem(total) > Mem(dom0..domN)

2) How about swap space? Do you use nfs exported dir
   from dom0 and install files in it for each domain
   to swap? Or else?

3) In order to have UML running faster, I use /tmp
   mounted on memory as a tmpfs with 2GB, and uml
   guests are using that for swap files. Will this
   approach make Xen any faster yet?

Many thanks!
