I'm about to install a whole bunch of DomUs, each with a different
operating system.
It's definitely faster not to use a file-backed block device. LVM is more flexible than partitions, and partitions are somewhat tedious (and dangerous) to set up. Is there any *measurable* overhead of using LVM as opposed to simple partitions? The two concerns I have are, how quickly can the physical disk sector number be calculated given the sector offsite in the device (either partition or LVM), and whether LVMs can be made physically contiguous.
Mike
