I may be a bit late to the “time to interactive” agent sandbox party, but I wanted to make sure our hypervisor absolutely MOGGED everyone else. 10x faster than Firecracker and 425x faster than Cloud Hypervisor. agx.so is the best agent infra platform, period.

Once the sandbox providers figure out performance and scale, the next hills to climb will be: - agent/harness integration (ie. Shelley from @exe.dev) - agent to agent communication (ie. side channels between your sandboxes) - agent tracing integrations (think raindrop AI)

I think that workload portability will be the next big AI sandbox unblocker. With the ridiculous wave of sandbox compute being deployed right now, having the ability to move long-running workloads between nodes (spot instances!) or even clouds is *the* silver bullet for both availability and cost.

I think it’s time to rewrite CRIU

At Google Cloud Next this week if folks want to chat about virtualization, filesystems, live migration, and eBPF!

In-kernel filesystem are going to destroy the FUSE ecosystem. Bringing your custom logic into the VFS directly is absolutely incredible for performance and latency.

Who’s going to FOSDEM in Brussels next week? DM me if you'd like to hang out, talk about high performance cloud infrastructure, live migration, eBPF, Spot Instances - or all of the above! Looking forward to meeting all the cool OSS folks!

Who’s going to re:invent in Las Vegas next week? DM me if you'd like to hang out, talk about high performance cloud infrastructure, live migration, eBPF, Spot Instances - or all of the above! Can’t wait to see everyone! #aws #reinvent #reinvent2025

Nice that one can use network-bypass techniques without crazy vendor frameworks or kernel mods. Even cooler that one can recreate iptables functionality like this for faster inter-host networking

People aren’t ready for the next blog post from @loopholelabs.io If you thought the XDP post was interesting (linked below) this next one is going to blow your mind. Here’s a hint: What do chess engines and NAT’s have in common?

Great post by @alex.sorlie.io

We finally decided to write out how we use XDP in our network plane for live network migrations and more specifically to process outgoing packets! This is the first in a series of promised deep dives into how Loophole's live migration tech works!

Who is coming to KubeCon NA 2025 in Atlanta?

I'm getting more and more excited about drop-in, frictionless infrastructure. Lots going on in observability, containers, cloud compute, etc. eBPF is part of it, so is monkey patching. Some interesting ones: @loopholelabs.io, @polarsignals.com, junctionlabs.io ﹩, subtrace.dev ﹩

Request: Topics for the @loopholelabs.io Blog I want to start posting some short-form blogs that go through the technical challenges of building @loopholelabs.io and how we’ve solved them. If folks have requests for content they’d like covered now’s the time to ask! Topics I have so far 👇

Just got to Malta for the company getaway! It’s really convenient that these EU outlets have a whole THREE USB-C outlets! So great.

If Asahi Linux ends up supporting M4 chips this year, I think adoption in datacenters will go through the roof

I think the most excited thing about this blog post is the one we get to publish next - a deep dive into how Architect works under the hood. There were so many “impossible” problems we had to solve to make Architect a reality - and now that we have I’m having a blast explaining how we did it.

@evanphx.dev this looks pretty cool loopholelabs.io/blog/rethink... built on OSS live migration tech that forked firecracker and related virtualization technology github.com/loopholelabs...

This looks super cool. Get up to 75% cost-savings of using spot instances without data loss or interruption. My mental model of what this does is the equivalent of vSphere vMotion, but for spot instance workloads running in the Cloud.

New blog post! Run any application on Spot Instances with zero downtime and 75%+ cost savings - and no code changes required. Architect eliminates the reliability concerns that previously made Spot Instances impractical for production workloads. ⬇️ Link in comments ⬇️

Who’s going to be at #aws #reinvent in Las Vegas next week? If folks are around I’d love meet up and talk about VMs (like running them on non-metal instances), #eBPF, and live migration (for VMs and GPUs)! DMs Open!

Hard won #eBPF lesson: bpf_redirect doesn’t work between interfaces where the sender has an xdp program loaded in native mode and the other has one loaded in generic mode (only with some cloud/os pairs)

Now that #KubeCon is done it’s time to head to #SC24 in Atlanta! Need to bring the gospel of live migration to the HPC folks…

Excited to be at #sc24 next week! Any talks I don't want to miss? 👀

The recording for my talk at KubeCon this week has just been uploaded! If you couldn't make it to the conference this year or want to watch our live demo of migrating a Kubernetes cluster from AWS to GCP to Azure with Architect again, you won't want to miss it […]

The demo gods were kind and @shivanshvij.com did an amazing presentation at Cloud Native Rejekts. While the recording is not available yet, you can watch the full thing at this timestamp of the live stream: www.youtube.com/watch?v=M1R0...

The best demo yesterday being able to live to migrate stateful workloads from one cluster to another, allows for blue/green upgrades of Kubernetes with zero downtime For the folks at loophole labs: github.com/loopholelabs #Rejekts #KubeCon #SLC #Kubernetes #CNCF

All I can say is, prepare to have your mind blown 🤯 @pojntfx’s talk from @KubeCon_ last year is pretty famous at this point, but it doesn’t come close to what we’ll be demoing this time. Cloud-Native VMotion is here, and you’ll be able to see it *live* during this talk.

We'll also be demonstrating for the first time how the native Kubernetes integration we Loophole Labs have been working on can live migrate regular Kubernetes pods and their network connections between cloud providers without downtime, how we can use the combination of live migration and spot […]

Are you into #OpenSource #virtualization, live migration, #Kubernetes, #eBPF, and bleeding-edge network migration tech? If you're at #KubeCon North America in Salt Lake City this week, don't miss my session where I'll live migrate a multi-node Kubernetes […] [Original post on mastodon.social]

Zero downtime talk by @shivanshvij.com at #rejekts2024 #Kubecon

Yes I miss my X network here but Im sure I will be able to build my 50k audience back here as well. If you like Kubernetes, cloud, wasm, content creation, DevRelthen do follow me as thats what I post about most times. See you around if uou are at #kubecon NA

Hey #Kubernetes folks! I’m going to be at #kubecon next week, speaking about container migration and virtualization! Who wants to hang out?
