Description

Run Fedora ARM VM on your x86 machine via libvirt + QEMU.

Setup

Functioning Fedora virt host.

How to test

Get the media

This is one way to do it and the paths are only relevant for F21 alpha media. For some more info, see: Architectures/ARM/F21/Installation#For_Versatile_Express_Emulation_with_QEMU

  • Download the F20 alpha minimal ARM image to $HOME
  • Extract the disk image: unar Fedora-Minimal-armhfp-21_Alpha-1-sda.raw.xz. Delete the original compressed image
  • Install virt-builder: sudo yum install libguestfs-tools-c
  • Extract the kernel/initrd from the disk image: virt-builder --get-kernel Fedora-Minimal-armhfp-21_Alpha-1-sda.raw
  • Copy the media to the the default libvirt image location: sudo mv Fedora-Minimal-armhfp-21_Alpha-1-sda.raw vmlinuz-3.16.1-301.fc21.armv7hl initramfs-3.16.1-301.fc21.armv7hl.img /var/lib/libvirt/images

Create the VM with virt-manager

  • Ensure qemu-system-arm is installed: sudo yum install qemu-system-arm
  • Start virt-manager, connect to 'QEMU', click the 'New VM' icon
  • On the first page, under 'Architecture Options' select 'arm'. The 'virt' machine type should be selected automatically
  • Select the 'Import install' option, go to the next page
  • Browse to the disk image, kernel, and initrd we moved in the previous step.
  • Set kernel args as: console=ttyAMA0 rw root=/dev/vda3 rootwait
  • Set the OS as Fedora 21.
  • Continue with the OS defaults, complete the install.
  • The guest should shortly start booting, and you should see text console output. After a bit of a wait, it should hit a text mode 'initial setup' where you can set a root password.

Create the VM with virt-install

Here's the relevant virt-install command:

sudo ./virt-install \
    --name f21-arm32 --ram 1024 --arch armv7l --import \
    --disk /var/lib/libvirt/images/Fedora-Minimal-armhfp-21_Alpha-1-sda.raw
    --boot kernel=/var/lib/libvirt/images/vmlinuz-3.16.1-301.fc21.armv7hl,initrd=/var/lib/libvirt/images/initramfs-3.16.1-301.fc21.armv7hl.img,kernel_args="console=ttyAMA0 rw root=/dev/vda3 rootwait"

Expected Results

No obvious errors occur.
