There are no vm's running. I'm new to xen, so my first question is: is this normal? If not, anyone know what the issue might be? Any help or pointers to a doc is appreciated. Yes, this is normal, or rather it is a limitation of the xen kernel. Note that it probably is not a real issue in practice, as any VM's that you create will come from the "missing" 32GB, only overflowing into the "real" 32GB when the first 32GB is used. I have a similar system with 48GB physical memory, and with 26 guests, each having 1 GB, the amount of memory shown in Dom0 is around 22GB.
