How to know actual memory/RAM installed in Xen Host system?

by

I always hear complaints on “actual memory ( RAM ) displayed in XEN host system is NOT CORRECT or how to know actual physical RAM in Xen host system” …

Knowingly/unknowingly we execute the command “free” command in Xen host system and will complain as mentioned. “free” command wont help you here, because ‘free’ will show you the physical memory available for Dom0 or Privileged Guest. This command can not help you in this situation or if you are running XEN virtualization in your system/setup.

But there is another way to get the exact information!!!. Thats what you are looking for, Isnt it ? here it is:

Fire the command “xm info” in your Xen host system and grep for “memory”

[terminal]
# xm info |grep -i memory
[/terminal]

Did you try and see the result? 🙂
