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>
