QEMU | openEuler

Current QEMU images are built on the openEuler. This repository is free to use and exempted from per-user rate limits.

QEMU is capable of emulating a complete machine in software without any need for hardware virtualization support. By using dynamic translation, it achieves very good performance. QEMU can also integrate with the Xen and KVM hypervisors to provide emulated hardware while allowing the hypervisor to manage the CPU. With hypervisor support, QEMU can achieve near native performance for CPUs. When QEMU emulates CPUs directly it is capable of running operating systems made for one machine (e.g. an ARMv7 board) on a different machine (e.g. an x86_64 PC board).

Supported tags and respective dockerfile links

The tag of each qemu docker image is consist of the version of qemu and the version of basic image. The details are as follows

Usage

In this usage, users can select the corresponding {Tag} based on their requirements.

• Pull the openeuler/qemu image from docker

  docker pull openeuler/qemu:{Tag}
  

• Run with an interactive shell

  You can also start the container with an interactive shell to use QEMU.

  docker run -it --rm openeuler/qemu:{Tag} bash
  

• Download a Bootable ISO

  Use wget to download your prefered bootable ISO image for the target architecture.

  wget [***]
  

  Replace this URL with your own ISO image.

• Start QEMU with the ISO(aarch64).

  Run the ISO in your container with qemu-system-aarch64.

  qemu-system-aarch64 \
    -m 512M \
    -machine virt \
    -cpu cortex-a57 \
    -cdrom ./your-os-image-aarch64.iso \
    -boot d
  

  Key options:

  • -m 512M: Allocate 512M RAM.
  • -machine: Generic ARM64 virtual machine.
  • -cpu cortex-a57: ARM CPU type.
  • -cdrom: Path to your ISO file.
  • -boot d: Boot from the CD-ROM drive.
