I was surprised just how poorly it works. My experiences with paravirt Xen have been: - Fine performance, as long as "normal" file I/O is being used. - Bad performance for "low-level" operations like file system creation This was with "raw device" based virtual disks. I haven't benchmarked file- backed virtual disks.
