But you have to have set the max memory you might balloon to (I think the parameter is mem=) on the domain''s kernel command line. If you don''t do that, Linux will make its memory map to small and it won''t be able to grow beyond its initial allocation.> everything goes fine except for the last domU. can''t allocate memory is > the error reported.

Do you fancy starting a wishlist section on the wiki? Or filing a "wishlist" item in the bugzilla if such a thing exists (not sure it does at the moment).

Upgraded my xen box to a gb of ram and had a bit of trouble expanding usage with baloon and maxmem. I figure I''m just being blond so I cut straight to teh chase and tweek the memory settings in the configuration files for each vm. everything goes fine except for the last domU. can''t allocate memory is the error reported. I check my math and I''m 5mb under my physical memory. I go through a couple of small reductions of memory usage to no avail. after a bigger decrease on the last domU memory allocation, all domU''s run. 1) how can one determine how much memory is really available for domU''s? 2) how much memory is really used by a domU? 3) in the furture, could memory be allocated as a percentage of total memory? -- http://www.wired.com/wired/archive/13.03/view.html?pg=5 The result of the duopoly that currently defines "competition" is that prices and service suck.
