When I was new on xen I had this very problem, that I was not able to figure out what is the actual amount of physical ram on xen host i.e Dom0. So sharing this little tip here for newbies that might be starting.
use “xm top” command to find out the actual physical ram.
Hope this will be helpful for someone.
