I need some clarifications: if I understood properly, in case of multiple disks connected to the same VM, iothreads is suggested because it uses 1 thread for each disks, right? Are multiple controllers a requirements?
What do you mean with multiple controllers as wrote in docs? Do I need multiple HW controller in the server and then use multiple disk images from multiple controllers (like disk0 on storage connected to controller0, disk1 on storage connected to controller1 an so on)

But with iothreads set, backup is not possible, so, how can I backup an iothreads VM ?
Any plans to add support for iothreads to backup procedure?

yes

>> Are multiple controllers a requirements?

in the vm yes (virtio-scsi-single controller, is 1 virtio controller for 1scsi disk)

no, only in the vm

if you storage support it, snapshot/backup (but it's out of scope of proxmox currently)

Any plans to add support for iothreads to backup procedure?
