qdev-ify virtio-blk.
First user of the new drive property. With this patch applied host and guest config can be specified separately, like this: -drive if=none,id=disk1,file=/path/to/disk.img -device virtio-blk-pci,drive=disk1 You can set any property for virtio-blk-pci now. You can set the pci address via addr=. You can switch the device into 0.10 compat mode using class=0x0180. As this is per device you can have one 0.10 and one 0.11 virtio block device in a single virtual machine. Old syntax continues to work. Internally it does the same as the two lines above though. One side effect this has is a different initialization order, which might result in a different pci address being assigned by default. Long term plan here is to have this working for all block devices, i.e. once all scsi is properly qdev-ified you will be able to do something like this: -drive if=none,id=sda,file=/path/to/disk.img -device lsi,id=lsi,addr=<pciaddr> -device scsi-disk,drive=sda,bus=lsi.0,lun=<n> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com> Message-Id:
