We compared different approaches for our virtualisation (kvm). We evaluted amongst others AoE and iScsi, decided then on iScsi, because a) AoE does not transmit checksums, iSCSI does b) AoE is non-routable ;) c) Vendor support for AoE is a little thin ;) At this stage we indeed also had some data corruption with KVM and LVM raw devices, but are still narrowing its cause down. (on Debian). It may or may not be important, but we so far tested with LVM-iSCSI-LVM only. (It may be the lvm-over-lvm which is troublesome, not kvm.)
