How to adjust the amount of RAM assigned to a virtual machine running in Parallels Desktop for Chrome OS Enterprise and Education Edition?
To assign a custom RAM value to a virtual machine, open Сrosh and execute the following command:
vmc adjust <vm_name>
vmc adjust PvmDefault memsize 8192
To switch back to the automatic assignment:
vmc adjust PvmDefault memsize auto
Note: this feature is available starting with Chrome OS 90, so if you are running an earlier version of Chrome OS, performing an update is required.
If such a virtual machine, with a custom RAM assignment, is deployed to an end-user, Parallels Desktop will attempt to run it as is, but if the pre-defined amount or memory exceeds that of the user's total host RAM, Parallels Desktop will reduce the virtual machine memory assignment by 1 to 2 GB depending on the configuration.
Please note that assigning more than 50% of host RAM to a virtual machine may lead to host performance degradation.
