Pre-built SocTalk demo VM images, published as GitHub Release artifacts on every v* tag of the soctalk/soctalk repository.

All images are the same Ubuntu 24.04 + K3s + setup wizard build, just converted to different virtual-disk formats. Pick the format your hypervisor consumes natively. There is no per-format functional difference.

Latest release

Current version: v0.1.4 — release page · all releases

• soctalk-demo-0.1.4.vhdx.xz — Microsoft Hyper-V (Generation 1)
• soctalk-demo-0.1.4.vhd.xz — Microsoft Azure (fixed-size, 1 MiB aligned)
• soctalk-demo-0.1.4.raw.xz — generic cloud import (GCP, OpenStack), dd to physical disk
• SHA256SUMS.txt — checksums for all of the above

All artifacts are compressed with xz -9. Decompress with xz -d <file>.xz.

Format chooser

Your platform	Download
Proxmox VE	qcow2 — qm disk import. See Run on Proxmox
libvirt / virt-manager / QEMU CLI	qcow2
KVM (RHEL/CentOS/Alma)	qcow2
VMware ESXi	vmdk — see Run on VMware ESXi
VMware Workstation / Fusion	vmdk
VirtualBox	vmdk — convert to VDI, then attach. See Run on VirtualBox
Microsoft Hyper-V	vhdx — Generation 1 VM (validated; the image boots via BIOS firmware, Gen 2 / UEFI is untested)
Microsoft Azure	vhd — direct upload to a Managed Disk → Image → VM. See Run on Azure
Google Cloud	raw — tar czf disk.tar.gz disk.raw && gcloud compute images create
OpenStack	raw — openstack image create --disk-format raw
AWS	vmdk — import as an AMI with VM Import, or build a native AMI with Packer. See Run on AWS
Bare metal	raw — dd if=disk.raw of=/dev/sdX bs=4M

Disk size

All images have:

• Compressed size: ~600 MB to 1.5 GB depending on format
• Decompressed apparent size: 60 GB
• Actual on-disk size after first boot: ~3 GB (qcow2/vhdx are sparse; raw and vhd are fixed-size but most of the 60 GB is zeros and compresses to nothing)

Build it yourself

The Packer harness lives in infra/packer/. With KVM and Packer 1.11+ on a Linux host:

git clone https://github.com/soctalk/soctalk.git
cd soctalk/infra/packer
packer init .
packer build -only="soctalk-demo.qemu.soctalk_demo" .

Builds in ~1 minute on a modern host with KVM acceleration. Outputs land in build/dist/: one file per format. See the Packer README for cloud-init seed configuration and the AWS AMI source.

CI workflow

build-packer-images.yml is workflow_dispatch-only — Packer builds aren't fired on every push because they're slow and consume runner minutes. Fire intentionally for a new release:

gh workflow run build-packer-images.yml -f version=0.1.4

The workflow runs:

1. build-wizard — Go build of the setup wizard binary.
2. build-qcow2 — Packer build producing all five formats; xz-compresses; uploads each as a separate workflow artifact; attaches to the GitHub Release on v* tags.
3. boot-test — Boots the qcow2 in a fresh KVM VM, waits for soctalk-firstboot to complete, runs a Playwright validator. Fails the workflow if the image is broken so a bad release never gets attached to a tag.
