http://pve.proxmox.com/pipermail/pve-devel/2012-August/003347.html "Hello list, right now when you select SCSI proxmox always use scsi-hd for device. With virtio-scsi-pci as scsihw we can also select scsi-block or scsi-generic. With scsi-block and scsi-generic you can bypass qemu scsi emulation and use trim / discard support as the guest can talk directly to the underlying storage. Also scsi-generic (needs guest kernel 3.4) is a lot faster then scsi-hd or scsi-block. What would be the expected way to integrate a selection between them in proxmox?
