I run on real block devices (in my case, linux software RAID 1 devices) for each of my umls. Im currently running 4 UMLS on a box, each with their own RAID 1 md device. Works out pretty well, the performance is good and the host system doesnt get anywhere near as bogged down when a guest does

[uml-user] performance of block devices resp. filesystems
