[pve-devel] integration of scsi-hd, scsi-block, scsi-generic

[Stefan Priebe]

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?

Greets,
Stefan
