This is current state of the patch series for people to comment on. I am using open firmware naming scheme to specify device path names. In this submission I addressed all comment from previous one and added option rom support and rebased to qemu upstream. Kevin can you double check that the names are usable by Seabios? Reading PC boot specification it looks like Seabios will not be able to take full advantage of this though. Only one BCV can be bootable, so only disk with lowest boot index will be bootable by Seabios. Is this correct? Names look like this on pci machine: /pci@i0cf8/ide@1,1/drive@1/disk@0 /pci@i0cf8/isa@1/fdc@03f1/floppy@1 /pci@i0cf8/isa@1/fdc@03f1/floppy@0 /pci@i0cf8/ide@1,1/drive@1/disk@1 /pci@i0cf8/ide@1,1/drive@0/disk@0 /pci@i0cf8/scsi@3/disk@0 /pci@i0cf8/ethernet@4/ethernet-phy@0 /pci@i0cf8/ethernet@5/ethernet-phy@0 /pci@i0cf8/ide@1,1/drive@0/disk@1 /pci@i0cf8/isa@1/ide@01e8/drive@0/disk@0 /pci@i0cf8/usb@1,2/network@0/ethernet@0 /pci@i0cf8/usb@1,2/hub@1/network@0/ethernet@0 /rom@genroms/linuxboot.bin and on isa machine: /isa/ide@0170/drive@0/disk@0 /isa/fdc@03f1/floppy@1 /isa/fdc@03f1/floppy@0 /isa/ide@0170/drive@0/disk@1 Instead of using get_dev_path() callback I introduces another one get_fw_dev_path. Unfortunately the way get_dev_path() callback is used in migration code makes it hard to reuse it for other purposes. First of all it is not called recursively so caller expects it to provide unique name by itself. Device path though is inherently recursive. Each individual element may not be unique, but the whole path will be. On the other hand to call get_dev_path() recursively in migration code we should implement it for all possible buses first. Other problem is compatibility. If we change get_dev_path() output format now we will not be able to migrate from old qemu to new one without some additional compatibility layer. Gleb Natapov (15): Introduce fw_name field to DeviceInfo structure. Introduce new BusInfo callback get_fw_dev_path. Keep track of ISA ports ISA device is using in qdev. Add get_fw_dev_path callback to ISA bus in qdev. Store IDE bus id in IDEBus structure for easy access. Add get_fw_dev_path callback to IDE bus. Add get_dev_path callback for system bus. Add get_fw_dev_path callback for pci bus. Record which USBDevice USBPort belongs too. Add get_dev_path callback for usb bus. Add bootindex parameter to net/block/fd device Change fw_cfg_add_file() to get full file path as a parameter. Add bootindex for option roms. Add notifier that will be called when machine is fully created.
