Re: Free Mem

[Gene <gh5046@xxxxxxxxx>]

Is the system BIOS showing 18 GB of memory?  What happens when you boot outside of Xen?  Do you see all 18 GB of memory?  (`cat /proc/meminfo` or `free -m`)

Hello,  

I am not sure if this is the correct Mailing list for the issue I have. 

I have a new system with 18GB of Physical memory on the system.  I loaded CentOS 6.4.  But when I boot into Dom0, I only see  (xm info) 2GB of total memory?   I set 1GB for Dom0, but I am not sure why the hypervisor does not see all the memory.
