Hi! I''m using Debian Etch with its xen-packages. I want to use a dynamic ram configuration for my DomU''s. I added these lines to my config-files: memory = "200" maxmem = "500" extra = "mem=500M" But the domU''s ram will not catch more than 200 MB ram. xm info shows me enough free ram. Best regards Thomas _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Re: [Xen-users] Debian Etch ignores the maxmem-option
You need to configure the guest so that it knows what to do with the memory. If you stick "mem=500M" onto the domain''s kernel command line (e.g. add it into the extra= parameter) then this will inform the guest that it may have up to 500M at some point in future. Otherwise it isn''t able to size its internal data structures correctly, and so it can''t expand when you ask it to. Hope this fixes the problem!
