Need to test your code on FreeBSD? On NetBSD/sparc64? On Solaris, Haiku, or Plan 9? One command:

anyvm --os freebsd -- uname -a

anyvm.py is a single Python file with no third-party dependencies. It picks a prebuilt, CI-verified guest image, downloads it, configures QEMU with defaults that actually work for that guest and that architecture, boots it, and drops you into an SSH session -- or runs your command inside the guest and exits. No libvirt, no Vagrant, no VirtualBox, and no image to build yourself.

pip install anyvm.py            # or: brew install anyvm-org/tap/anyvm
anyvm --os freebsd

Prefer a container? docker run --rm -it ghcr.io/anyvm-org/anyvm:latest --os freebsd

Or launch straight into a ready-made cloud environment:

A few more things it does out of the box:

# Pick a release and a CPU architecture
anyvm --os netbsd --release 11.0 --arch sparc64

# Share a host folder with the guest
anyvm --os freebsd -v "$PWD:/data"

# Boot a desktop image and open it in your browser
anyvm --os openbsd --release 7.9-xfce

• One file, standard library only. Nothing to compile, nothing to vendor. Copy anyvm.py around and it works.
• Images are prebuilt and boot-tested. Every image in the matrix below is produced and verified by its own builder repository in this organization, on every release -- so a green check means that guest really boots on that architecture today.
• Acceleration is automatic. KVM, HVF or WHPX is detected and used when available, with a clean fall back to TCG emulation when it is not.
• Folder sync that works everywhere. Six backends (rsync, sshfs, nfs, sys-nfs, scp, 9p), including a bundled pure-Python NFS server so even Windows and macOS hosts can export a directory without root.
• A graphical console in your browser. The built-in VNC web UI starts by default, with clipboard, fullscreen, optional password, and one-flag public tunnelling via --remote-vnc.
• Desktops, not just shells. XFCE, GNOME, KDE, MATE, LXQt and more ship as ready-to-boot desktop images for several guests.

Hosts: Linux, macOS and Windows, natively on x86_64 and arm64. See the anyvm README for the full host-to-guest support table.

The same images run inside the vmactions GitHub Actions -- freebsd-vm, openbsd-vm, netbsd-vm, solaris-vm and friends -- which execute your CI steps inside a real BSD or illumos guest on GitHub's Linux runners.

Images

base-builder is the single template every image builder is generated from. Each guest then gets its own builder repository, which builds, boots and publishes that guest's images:

blissos · dragonflybsd · freebsd · ghostbsd · haiku · hurd · midnightbsd · netbsd · nextbsd · omnios · openbsd · openeuler · openindiana · plan9 · solaris · tribblix · ubuntu
