First release of #KVMserver fast per-request isolation for Linux executables using #TinyKVM.
In a React page rendering benchmark with #Deno we see overhead of just 10s of µs, far faster than existing alternatives using v8 isolates (ms) or JS in WebAssembly (10s of ms).

TinyKVM in Varnish and some Deno
Previously, I said that TinyKVM runs regular Linux ELFs and I use this to test my programs on the terminal like a regular program before I load them in Varnish.

Somewhat orthogonally I’ve been trying to get fast request isolation working JS and have spent the past couple of months working with the TinyKVM author on building KVMServer which runs my React server rendering benchmark with Deno in under a ms. (x86_64 only for now.) github.com/libriscv/kvm...

They mentioned Firecracker and Cloud Hypervisor, but several new projects are emerging in this space
Edera is pushing the boundaries of secure workloads, while projects like TinyKVM demonstrate how much further we can go

This is an area I’m interested in because I want to see fast per request isolation for server rendering of react pages. The best approach I’ve found so far is using TinyKVM’s fast snapshot restore which has just 10% overhead or so.

tried playing with the tinykvm coverage thing again; im now assembling 12 byte trampolines that im pointing it at, so that a coverage instrumented `jne disp` turns into `jne +5; jmp fallthrough; jmp taken;` that we redirect to from the guest kernel ISR. which is a lot nicer in.
