We use qemu-nbd to allow us to mount the filesystem as a block device. $ $HOME/git/qemu/qemu-img info trusty-server-cloudimg-arm64-disk1.img | grep size: $ $HOME/git/qemu/qemu-img resize trusty-server-cloudimg-arm64-disk1.img 8G Resize the qcow2 disk size to whatever you want. We have to perform three steps to resize the image.
#INSTALL QEMU SYSTEM X 64 BIT FREE#
By default Ubuntu only leaves about 400MB of space free for use and becomes pretty cramped for any real work. Once the image is downloaded we need to resize the filesystem. It's important to note the "-disk1.img" files are qcow2 images which are QEMU's native disk format. With that in mind I selected this 300MB image. Grabbing the latest nightly image means fewer package updates once we're done customizing the image. I like using LTS as Ubuntu is a little more careful about package updates/changes to their long-term releases. I also used Ubuntu 14.04 LTS on an x86_64 system to run QEMU and to prepare the Ubuntu guest OS image.įirst up we need to fetch an appropriate image. When researching this I used a git checkout of QEMU HEAD as 35858955e6c6f9ef41c199d15457c13426ac6434. Once deployed in QEMU they work just like any other Ubuntu installed device.
#INSTALL QEMU SYSTEM X 64 BIT INSTALL#
These images contain a full base OS install and only require a bit of tweaking. The reason I chose Ubuntu is for one important reason: they publish nightly builds of their OS for cloud machine deployment. The goal of this post is to take the installation one step further and get a full-fledged Ubuntu Linux distribution running in QEMU. An excellent blog post by Alex Bennée outlines the steps needed to get QEMU installed on your Linux system ready to run 64-bit ARM code. Thankfully the good people working on QEMU have recently added aarch64 support. Unfortunately the same is not true for 64-bit ARM devices. There are several low-cost 32-bit ARM devices on the market today.
