Re: [Xen-users] swap size on dom0

[Geoff Kirk <geoff.k@xxxxxxxxxxxxxxxxxxx>]

Yes that sound a lot too much. 1st point i would make is to pass dom0_mem=xxxxx 
where xxxxx is number of kilobytes to assign to dom0 (not including domU's) 128 
megabytes should be more than enough (xxxxx=128000). 2nd point as a general 
rule i find its then good to use same amount of swap space as i have ram in 
that case would be 128 megabytes. I have heard in the past it used to be 
suggested 2x ram for swap but that much is not often needed. In general a dom0 
should not require so much ram because it doesn't as a rule do anything but 
serve domU's. 128 megabytes of each should be plenty.
