I am seting up my new Xen 2.0 server. In the examples Domain0 is given 128MB Ram. I got greedy and tweaked it down to 64 MB; things got bad. But how little can Domain0 do with (assuming it is only used to administer Xen)?Any success stories with < 128MB? -- "Wherever there is fun there is Java" ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.

Some of the memory dom0 get''s booted with actually gets returned to Xen, so you''ll probably find the memory usage reported by ''xm list'' is a few MB lower than the amount you started it with. Are you sure you''re not starting some other application in your rc scripts that is consuming a lot of memory? Perhaps configure a swapfile...

I''ve slightly modified the dom0 kernel to get unusefull parts out but i think the reduction isn''t huge (1 or 2 Mo) i''m running a 2.4.27 kernel HTH Matthieu ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
