Hello:

As you can see from xm info below, we have almost 200GB of memory in our server running CentOS 5.2. But, we can't seem to allocate all the memory. For some reason, the total memory that can be allocated maxes out at 188.4 GB. None of the VMs has hit its own max-mem limit. Even when we set one of the VM's memory so the total is above 188.4 GB, its memory allocation stops when the total memory allocation reaches 188.4 GB.

Thanks for your assistance.
