Hi. Is there a formula for calculating a good value for dom0_mem based
on the expected number of VMs, bridges, block devices, etc? I seem to
recall seeing someone mention something like this, but now can't find
it in the archives.

And second, how does memory allocation to dom0 affect overall system
(and VM) performance? I'm guessing we don't want to over-allocate RAM
to dom0 when it could be put to better use in the variuos guest

Thanks for your insights!
