FWIW, if you're comfortable with command-line, here's a way to use QEMU with `virt-builder`[a] and libvirt (the virtualization API): (1) Download a Fedora image (or any one of the images that `virt-builder` supports: `virt-builder --list | less`) $> virt-builder fedora-36 --format qcow2 \ -o vm1.qcow2 --root-password secret (2) Import the image to libvirt: $> sudo virt-install --name vm1 --ram 4096 \ --disk path=/var/lib/libvirt/images/vm1.qcow2,format=qcow2 \ --nographics --os-variant fedora-36 --import Then you can do various operations via `virsh` (the shell tool). Start a VM, and see the boot process on the serial console: $ sudo virsh start --console Create a snapshot: $ sudo virsh snapshot-create-as vm1 snap1 "Clean Fedora 1" With this kind of snapshot (called "internal snapshots"), the original and its delta, i.e. the snapshot, are stored in a single disk image file; this is convenient for moving it across machines. This only works with QCOW2 images. To revert to the snapshot: $ sudo virsh snapshot-revert vm1 snap1 And so on[b].
