Hi, @kowalski7cc can you share details, why you use virtio agains VirtIO SCSI single ?

Thanks.

Your comment made me doubt about my choice of virtio, and so after some websearch I found the following pages:

https://forum.proxmox.com/threads/virtio-block-still-first-choice-for-disk-performance.119111/
https://forum.proxmox.com/threads/virtio-vs-scsi.52893/
https://pve.proxmox.com/wiki/Performance_Tweaks

Which sometimes are a bit confusing on wich VirtIO block and VirtIO SCSI seems to be faster. I'd expect to be vio block because a slimmer stack, but they state SCSI one it's better mantained.
