HHVM (HipHop Virtual Machine) vs LXD: What are the differences?

What is HHVM (HipHop Virtual Machine)? An open-source virtual machine designed for executing programs written in Hack and PHP. HHVM uses a just-in-time (JIT) compilation approach to achieve superior performance while maintaining the flexibility that PHP developers are accustomed to. To date, HHVM (and its predecessor HPHPc before it) has realized over a 9x increase in web request throughput and over a 5x reduction in memory consumption for Facebook compared with the PHP 5.2 engine + APC.

What is LXD? Daemon based on liblxc offering a REST API to manage containers. LXD isn't a rewrite of LXC, in fact it's building on top of LXC to provide a new, better user experience. Under the hood, LXD uses LXC through liblxc and its Go binding to create and manage the containers. It's basically an alternative to LXC's tools and distribution template system with the added features that come from being controllable over the network.

HHVM (HipHop Virtual Machine) and LXD are primarily classified as "Virtual Machine" and "Virtual Machine Platforms & Containers" tools respectively.

"Very fast" is the top reason why over 29 developers like HHVM (HipHop Virtual Machine), while over 4 developers mention "More simple" as the leading cause for choosing LXD.

HHVM (HipHop Virtual Machine) and LXD are both open source tools. HHVM (HipHop Virtual Machine) with 16.1K GitHub stars and 2.85K forks on GitHub appears to be more popular than LXD with 2.28K GitHub stars and 531 GitHub forks.

Decided

lxd/lxc and Docker aren't congruent so this comparison needs a more detailed look; but in short I can say: the lxd-integrated administration of storage including zfs with its snapshot capabilities as well as the system container (multi-process) approach of lxc vs. the limited single-process container approach of Docker is the main reason I chose lxd over Docker.

Docker

The Docker Platform is the industry-leading container platform for continuous, high-velocity innovation, enabling organizations to seamlessly build and share any application — from legacy to what comes next — and securely run them anywhere

Laravel Homestead

Laravel Homestead is an official, pre-packaged Vagrant "box" that provides you a wonderful development environment without requiring you to install PHP, HHVM, a web server, and any other server software on your local machine. Homestead runs on any Windows, Mac, or Linux system, and includes the Nginx web server, PHP 5.6, MySQL, Postgres, Redis, Memcached, and all of the other goodies you need to develop amazing Laravel applications.

Vessel for OpenClaw: Managed AI Agents on Private VMs

300,000+ OpenClaw instances are currently exposed on the public internet (Shodan: port 18789). Most self-hosted setups miss the tunnel, skip the required flags, share containers. When your agent processes untrusted input and holds access to your accounts, that gap matters. Vessel provides private, dedicated hosting for OpenClaw agents. Each agent runs on its own GCP e2-standard-2 VM, its own kernel, its own disk, no shared memory with other tenants. No public IP. No port 18789 exposure. All traffic routes through an encrypted Cloudflare Tunnel. Secrets are managed separately from the runtime. Provision from a web dashboard, connect to Slack, Discord, or WhatsApp, and destroy when done. Your agent's data stays on your VM, your own Vessel.
