User-Mode Linux was an alternative hypervisor that could run the appliance, instead of using qemu. It had many limitations including lack of network, and UML support in Linux has been semi-broken for a long time. It was also slower than KVM on baremeal in general and had various corner cases which were much slower including the emulated serial port which made bulk uploads and downloads painful. Also of course it lacked qemu-specific features like qcow2 or any network-backed disk, so many disk images could not be opened this way. This was never supported in RHEL.
