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.
What is the hardware limit for the server?
Hi James,
The server is Sun x4600 M2 which can handle 256GB memory according to Sun/Oracle Document... During the boot up, I can see the all the memory being counted. So, I think the BIOS is recognizing all the memory.... Thanks.

Do a 'cat /proc/meminfo' to find out how much memory you actually have available on the server.
Hi Benjamin:
I ran meminfo in dom0 and it show what has been allocated to it which is around 16GB.
Best regards,
HS
