Hi,
 
is the line
dom0_mem=<memory size>
still useful?
I mean I've commented out this line and dom0 does take 3.2 GB of RAM, which limits my domU a bit. If I do limit dom0 to lets say 256MB, would that make any difference?
 
Thanks
Jan

If you want to avoid ballooning failures, the option may be
useful, but as
long as your dom0 doesn't really allocate all that memory
(so that the
balloon driver can't grab it anymore) there should be no
problem omitting
it. (256Mb for dom0 would be questionable at least - I'd
certainly not set it
to this small a value.)
