Hello:<div><br></div><div>As you can see from xm info below, we have almost 200GB of memory in our server running CentOS 5.2. But, we can&#39;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&#39;s memory so the total is above 188.4 GB, its memory allocation stops when the total memory allocation reaches 188.4 GB.</div>
