XO - change control domain memory?

gskger

What is the correct way to change a hosts control demoin memory using XOA or Xen Orchestra from source (XenCenter is not an option since I am on 8.2.0RC)? I searched the documentation and the forum, but even my google-fu did not help.

/opt/xensource/libexec/xen-cmdline --set-xen dom0_mem=<nn>M,max:<nn>M on the command line works of course

It's not exposed (yet) in the UI. When you are in doubt, feel free to search in XO Issues:

https://github.com/vatesfr/xen-orchestra/issues/2218

Feel free to ask for it in the issue. It's not a priority, but if more people ask, we can make it real.

Thank you Olivier , did not see that. Changing the control domain memory is nothing one does frequently and it is perfectly ok to use the CLI. ~~Maybe adding this to the documentation could be helpfull~~. Already in the documentation - how did I miss that ?

I'm not against exposing this in the UI, it might be not that difficult. However, more traction will obviously make it possible
