The concept of a machine type represents the ABI or HW revision of the virtual hardware being used and presented to the guest. It is in general recommended to be upgraded on an upgrade of qemu/kvm, but so far there was no interface for that which was easy to use.
Such a change is picked up by a domain when it is (re-)started as the virtual HW can't be replaced at runtime.
Libvirt support various hipervisors and all have machine types. But a machine type in the sense that virt-machine-type cares about are only really present in a qemu/kvm based hipervisor.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snapd can be installed from Manjaro’s Add/Remove Software application (Pamac), found in the launch menu. From the application, search for snapd, select the result, and click Apply.
Alternatively, snapd can be installed from the command line:
sudo pacman -S snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install virt-machine-type, simply use the following command:
sudo snap install virt-machine-type --edge
Browse and find snaps from the convenience of your desktop using the snap store snap.
