How do I measure the actual overall free/used physical RAM?

Hi,

AFAICS even in dom0 free and the XFCE panel widget show the RAM of the qube itself, not the overall RAM.

How can I check the actual overall free/used physical RAM?

You can use xentop in dom0

Thank you.

I’m wondering why memory allocated to stub domain(s) isn’t presented in qui-domains, either as a summary to what is already allocated to the qube, or as (+xxx M) for example.
The latter way we would get better picture of total memory used as well as which qubes are HVMs.
Not to say that I’m clueless why xentop’s header summary isn’t already included in qui-domains.

After a long search I found a solution that fits my needs: I open a small Dom0 terminal window and run:

watch -n 30 'xl info | grep memory'

xentop provides much more information, but sometimes I want to keep it simple .

Not a reliable source for any practical purpose :frowning: search the forum for previous discussions.
