This is by design and only info for the control domain (aka Dom0). You should read more about how XCP-ng works, as it seems there's mucht you would learn. Also using a Notebook PC has good chance, that hardware (sooner or later) might not work as expected, as Notebooks are an unsupported and not targeted platform.
Thank you so much for your response. I would read further. Yes, I know a notebook it is not the correct hardware to work with xcp-ng, but I am using this for lab purposes at home. And at the moment it has been working very well and it has exceed my expectations.
What I wanted to do is to monitor that machine with check_mk. Is there a way to get the ram information from the machine and not the control domain? Thanks, Bernardo
There is total RAM available for a virtual machine (eg 6GiB) that's "reserved" for it. Even if you use 500MiB inside, the total RAM space used will be 6GiB anyway.
There's so advanced mechanism to have a more dynamic allocation, but it's not for general use cases.
But the main total ram available it is not showing that on the output of cat /proc/info Please see attached image

Sorry I don't understand what you mean.
My machine has 6GB RAM... but it is showing 600MB... but above he told me that reflects the control domain RAM... I am wondering if I can get the real memory ram information of my machine... ?

The control domain isn't your whole physical machine. It's a virtual machine. This virtual machine got a max amount of RAM that's not your 6GiB otherwise how on earth you'll be able to start another virtual machine?
Take a look at your screenshot, in the host view and just scroll down, you have a progress bar filled with the RAM usage.
You won't start a VM inside your control domain. You need to get first how Xen works:

You are not understanding me either. Could you please read again my first question and you will see what I really want to know Thanks

You can see the total physical memory with: xl info
There isn't any question in your first post. I suppose you meant your 2nd post:
Is there a way to get the ram information from the machine and not the control domain?
xe
CLI or xl info
as @Wescoeur saidThe facts.
In short, your question is: "how could I get the host installed RAM reported to check_mk
", right?
In short yes... I will edit the issue as you mentioned

So this is not a bug nor a feature request, the best place to ask for this would be https://xcp-ng.org/forum
See you there!
Thank you Olivier. See you there!
Hello guys,
I have 2 machines that have 6GB but the below command it is showing that is has 600MB... You can also see the attached image how much ram does it has my machine.
