vmlab backend
test backend
QEMU/KVM VM testlab backend — Linux or Windows guests, shelling out to the sibling vmlab CLI.
The vmlab backend runs tests in disposable QEMU/KVM VMs by shelling out to the sibling ../vmlab CLI. It supports both Linux and Windows guests and is the only backend that can run scenarios.
