[PVE-User] Questions about virtio-scsi-pci

[Alexandre DERUMIER]

mmm, same here, it's working with scsi0 but not scsi2.


with virtio-scsi, 1 single controller is used for all scsiX disk.

I'm not sure if boot is working withh all drives.
maybe it's a qemu bug or seabios limitation,I'll try to check that.


(with classic virtio-blk, it's 1controller by disk, so no problem for booting)

Now I discovered, that the numbering of the devices seems to be the 
problem. If I rename scsi2 to scsi0 it works. scsi2 was the result of 
adding/removing several devices. 
More testing shows that if I connect two devices first with virtio0: and 
the second with scsi1: the BIOS doesn't show the scsi device but the OS 
can find the device. So maybe it's a problem of SeaBIOS. E.g. connecting 
only one volume with virtio2: works fine.
