I Folks, Wonder if anyone has any ideas on this one? I have a server with 16GB RAM 1.5GB reserved for Dom0 If I run xm or xl list I get exactly 14GB of DomU''s Xm or xl info shows 281 MB Free total_memory : 16374 free_memory : 281 Which means XEN thinks I have used 14.22 GB for DomU''s CentOS 5.7 64bit Xen 4.1.2 (SolusVM On Top) Is this some XEN thing that is not well documented, e.g. to create a 1024 MB RAM DomU XEN actually requires an additional 3 MB overhead or something like that? Thanks, and any suggestions no matter how small or based in theory only are welcome.
