Goal
Create VMs with file backed RAM in order to make them suppressible from RAM.
Such VMs will leverage cache and be fast, but as soon as node memory arises, those VMs will be pushed out of RAM, because the cache will be dropped.
This feature is configurable on a VM/workload level.
We should create an instanceType for this.
User Stories
- As a Vm user, I want create a suppressible VM for my low prio workload, so that the VM will use RAM if available, but otherwise be suppressed from RAM in order to free memory space.
- As a cluster admin, I want to have an instanceType class for suppressible VMs, so that my users can easily create suppressible VMs for their low priority workloads.
Non-Requirements
- List of things not included in this epic, to alleviate any doubt raised during the grooming process.
Notes
