[LSF/MM/BPF TOPIC] Virtual Machine Memory Passthrough

[Pasha Tatashin <pasha.tatashin@soleen.com>]

Hello,

As a part of an ongoing work of replacing some containerized work load
with virtual machines within Google, I have worked on making the
memory translations faster.

I would like to propose the following topic for this year's LSF/MM/BPF:

Discuss  a set of techniques that can improve the guest performance,
memory footprint overhead, observability, and manageability of virtual
machines by hypervirtualizing the guest memory to the extreme. The end
goal is to allow very lightweight virtual machines to be closer in
performance to the containers.

The following items are going to be discussed in this topic:
- Reducing the cost of SLAT page table translations.
- Reducing the memory footprint overhead.
- Reducing the memory management overhead.
- Increasing the observability of guest memory.
