When building Edera (product from article), I also had the added problem of the virtual networking gap where I was bridging a 10Gbit NIC over a virtual interface, and I had weird performance bouncing between 3Gbit and the full 10Gbit. Lucki

(CTO of Edera here) Great point! We also try to factor that in as well. Steven (the author) will cover that in part 2!

All of that is a yes, plus compressed memory is a big component of macOS.

When running on bare metal, the CPU performance is within 1%, so usually quite well! Hardest thing is I/O, but we do a lot to help with that too.

I'd say the limitation has been that sometimes we have to implement things by hand. But it has enabled us to do things that others can't achieve since KVM is a singular stack in many ways. For example, VFIO-PCI is largely the same

I was more specifically referring to the fact that to implement threads in gVisor, it calls to the go runtime, which does make calls to clone() (not fork()), but I see the pushback :) I think it's a small distinction. fork() itself isn

This is why you can't build these microVM systems to just do isolation, it has to provide more value than that. Observability, policy, etc.

This is the thesis of our research paper here, a good middle ground is necessary: https://arxiv.org/abs/2501.04580

The reason why virtualization approaches with true Linux kernels is still important is what you do allow via syscalls ultimately does result in a syscall on the host system, even if through layers of indirection. Ultimately, if you fork() i

This is a big reason for our strategy at Edera ( https://edera.dev ) of building hypervisor technology that eliminates the standard x86/ARM kernel overhead in favor of deep para-virtualization. The performance of gVisor is of

Not sure why this says East coast, I am also affected here in Seattle.

Hi! I’m the CTO of Edera and discovered this bug with my colleague Steven! The story of this bug is interesting. We were both up late at night working on GPU support on the Edera platform, and we had just pulled an NVIDIA container image. W
