Hello,
During today’s Community meeting, memory usage on virtual environments was discussed. In summary, the memory requirements for each VM has increased significantly (see bug: https://bugs.launchpad.net/bugs/1826445 ).
An alternative was mentioned, during the deployment it’s possible to limit the amount of memory that starlingx is going to use. Does somebody has the instructions to implement such limits? It’ll help us a lot to continue working with Virtual Environments.
Thanks in advance.
Cristopher Lemus
