March 6, 201511 yr When installing a Windows 7 guest, I use the virtio drivers twice. Once to recognize the iso during installation of the OS, and then after the OS is installed to work with drives (like an optical drive). Can someone explain the difference between the two options (scsi and scsi-passthrough) and when you should use one vs. the other? Thanks!
March 7, 201511 yr When assigning a virtual block device, it's virtio-scsi, as it's still an emulated device. When assigning a physical block device, it's virtio-scsi-passthrough. This is an over-simplified answer, but you can read more here: http://wiki.qemu.org/Features/VirtioSCSI
