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.

 

Anthony.
