About Docker Container
This GitHub repository provides a Docker container configuration for running QEMU virtual machines. It supports nearly all common disk and image formats, offers a web-based viewer for VM access, and enables near-native performance via KVM acceleration. Users can customize VM CPU, memory, and storage allocation, use hardware-accelerated graphics, enable USB passthrough and host folder sharing, and choose from multiple networking options. The container automatically downloads images for a list of popular Linux distributions, and also accepts custom image URLs or local bound image files. Notable limitations include lack of KVM support on Docker Desktop for Linux, macOS, and Windows 10, with KVM access only available on Windows 11 with nested virtualization enabled or Linux hosts with KVM support. Default VM resources are set to 2 CPU cores and 2 GB of RAM unless manually adjusted.

Docker Container FAQ
How do I select the operating system for the virtual machine?
Set the BOOT environment variable to a supported OS identifier or a direct URL to a custom image file.
Can I use a custom virtual machine image not on the supported OS list?
Yes, set BOOT to the image's direct URL, or bind a local image file to the container's /boot.iso, /boot.img, or /boot.qcow2 path.
How do I adjust the virtual machine's CPU, RAM, or disk size?
Modify the relevant environment variables in your Docker Compose or run configuration to set custom resource allocations.
