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.
