[SOLVED] Performance comparison between ZFS and LVM

[tomtom13]

I quote it in full above (highlighting mine) to give the context, but I still do not understand the comparison, you could instead however e.g. compare with what e.g. Red Hat has been suggesting since a while (they do not do ZFS, obviously):

I think you're trying to split hairs here. Lvm has more features than RAW but not as many as ZFS. LVM allows to have several VM's on single storage device, and device passthrough should be one per VM. From my (and few other admins) experience LVM seems to be more reliable than RAW disk passthrough but has a tiny penalty of speed.
