How important is keeping them alive? I can volunteer to "maintain" them which I anticipate won't be much effort (plus I'm used to looking after obsolete SCSI equipment). The hardware is obsolete, so the mechanics of their emulation isn't going to change, the only potential risk is changes in the guest to host transmission layer that breaks something. On the other hand, I've got to say I use virtio-scsi in all my VM testing environments, so the maintenance will likely only be reacting when someone else reports a problem. James
