QEMU Docker Machine Driver Plugin

The Docker Machine plugin for QEMU enables the use of the QEMU hypervisor with Docker-Machine

Requirements

Linux

• QEMU (qemu-system-x86_64 & qemu-img) in path -2.5.0+ Tested but other expected to work
• KVM available

Windows

• QEMU 2.9.0+
• Intel HAXM driver

Install from Binary

Please see the release tab and place the plugin in your PATH

Usage

The usual Docker Machine commands apply:

docker-machine create --driver qemu qemumachine
docker-machine env qemumachine

On Windows QEMU_LOCATION must be set to the location where the

Limitations

• Ports: QEMU will not generally respect forwarding the network traffic to the docker-machine. During creation, you need to explicitly state the port ranges you wish to use For example: --qemu-open-ports 8022,1111,1231-1235
• Mounts: Using mounts into containers is not supported.
• Concurrent usage: One instance of a machine using QEMU driver is possible at this time. The provisioner does not handle NATd Docker Ports.
