Run Ubuntu as the User VM OS¶
This tutorial assumes you have already set up the ACRN Service VM on your target system following the instructions in the Getting Started Guide.
Install these KVM tools on your development system:
sudo apt install qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager ovmf
Ubuntu version: 20.04
ACRN hypervisor tag: v3.0
Service VM Kernel version: release_3.0
Build the Ubuntu KVM Image¶
This tutorial uses the Ubuntu 20.04 desktop ISO as the base image.
Download the Ubuntu 20.04 desktop ISO on your development machine:
Install Ubuntu via the virt-manager tool:
Verify that you can see the main menu as shown in Figure 13 below.
Right-click QEMU/KVM and select New.
Choose Local install media (ISO image or CD-ROM) and then click Forward.
A Create a new virtual machine box displays. Click Browse and select the Ubuntu ISO file that you downloaded earlier. If not already auto selected, choose the OS type: Linux, Version: Ubuntu 20.04 LTS and then click Forward.
Choose Enable storage and Create a disk image for the virtual machine. Set the storage to 20 GB or more if necessary and click Forward.
Rename the image if you desire. Check the customize configuration before install option before you finish all stages.
Verify the Firmware and Chipset settings are as shown in this Overview screen:
Click Apply and Begin Installation (in the top left corner). Complete the normal Ubuntu installation within the QEMU emulator. Verify that you have set up the disk partition as follows:
/dev/vda1: EFI System Partition
/dev/vda2: File System Partition
Upon installation completion, click Restart Now to make sure the Ubuntu OS boots successfully. Save the QEMU state and exit.
The KVM image is created in the
/var/lib/libvirt/imagesfolder. Convert the
imgas the root user:
cd ~ && mkdir ubuntu_images && cd ubuntu_images sudo qemu-img convert -f qcow2 -O raw /var/lib/libvirt/images/ubuntu20.04.qcow2 ubuntu_uservm.img
Launch the Ubuntu Image as the User VM¶
In the Getting Started Guide, we used the ACRN configurator to create a scenario with a Service VM and an Ubuntu ISO image for the post-launched User VM. We can use that same scenario with a slight edit for the User VM image name by changing the file name in the Virtio block device for the post-launched User VM.
Change the virtio block device to use the new Ubuntu image we created using KVM above:
Then save this new configuration and write out the updated launch script.
ubuntu_uservm.imgand the updated launch script from the development system to your target system. For example, if the development and target systems are on the same network, you could use
scp ~/ubuntu_images/ubuntu_uservm.img ~/acrn-work/MyConfiguration/launch_user_vm_id1.sh user_name@ip_address:~/acrn-work/
On the target system, launch the Ubuntu User VM after logging in to the Service VM:
cd ~/acrn-work sudo launch_user_vm_id1.sh
