disks (IDE, virtio):
qemu -drive file=disk1.img,if=none,id=disk1
-netdev type=user,id=net1 -device e1000,netdev=net1,bootindex=1
Given the command above, firmware should try to boot from the e1000 NIC

too, it should try the virtio disk, and then the IDE disk.
== Limitations ==
1. Some firmware has limitations on which devices can be considered for
booting. For instance, the PC BIOS boot specification allows only one
disk to be bootable. If boot from disk fails for some reason, the BIOS
-won't retry booting from other disk. It still can try to boot from

floppy or net, though.
2. Sometimes, firmware cannot map the device path QEMU wants firmware to
can natively boot from, but if firmware relies on an option ROM for
booting, and the same option ROM is used for booting from more then one
device, the firmware may not be able to ask the option ROM to boot from
-a particular device reliably. For instance with PC BIOS, if a SCSI HBA
+a particular device reliably. For instance with the PC BIOS, if a SCSI HBA
has three bootable devices target1, target3, target5 connected to it,
the option ROM will have a boot method for each of them, but it is not
possible to map from boot method back to a specific target. This is a
-shortcoming of PC BIOS boot specification.

cannot be used on a guest with simple usb passthrough since it will then not be
available on the client, possibly locking the computer when it is "removed". On
