> Someone, anyone, tell me which hypervisor doesn't enforce a memory limit on VMs?
They don’t mean the memory usage is allowed to grow indefinitely.
They mean, if your laptop has 32 GB RAM, and if your OS and apps consume 20 GB, it’s using 20 GB RAM.
If a VM has 32 GB of vRAM allocated, and the OS is aggressively caching, that VM will consume 32 GB of RAM on the physical host, even if only 20 GB of vRAM is being used within that guest VM.
Of course, every good hypervisor will have a way to prevent this from happening, so the article does seem disingenuous on this point.
