Virtual machines scale well specifically because you can overprovision them.

While hypervisors are <i class="">very</i> good at task prioritization, they're not perfect. If the hypervisor can't schedule processor time when FS needs it because the CPU cores are momentarily taken on other tasks, there's not a whole lot FS can do. This is not an issue with just FS, but with all real-time applications. In most apps, even large clock skews and bad hypervisors schedulers can go completely unnoticed. If there's consistent 5-10ms every time you click to load a web page, you'd probably have no idea. If there's 5-10ms jitter every time you try to read 20ms of audio, you have <i class="">really bad</i> audio.
