Incus 2-minute quick install on Ubuntu
Incus
is a LXD fork which I recommend due to its more liberal license. See LXD has been re-licensed and is now under a CLA for more info.
Installing & configuring it on Ubuntu is easy:
sudo apt -y install incus qemu-system
incus admin init --minimal --storage-backend dir
usermod -aG incus-admin $USER
You need to log out and back in for the group change to take effect (so you’re able to access Incus as normal user).
