[PATCH V3 0/7] qemu: support updating device's bootindex

[Jiang Jiacheng]

Support updating device's(support cdrom, disk and network) bootindex
online in virDomainUpdateDeviceFlags. The new bootindex will take effect
after guest rebooting. Enable bootindex can be set to 0, it means cancel
the device's bootindex.

To use this feature, we need to get the device's xml first and modify
the boot order in the xml, then use 'virsh update-device <domain> <xml>
--flag' to update the bootindex. Note that the flag should be --config
or --persistent if the vm is running.

Jiang Jiacheng (7):
  qemu: Introduce qemuDomainChangeBootIndex to update device's bootindex
  qemu: Marking a device's bootindex can be changed
  qemu: check the bootIndex could be changed or not
  qemu: Support update disk's bootindex
  qemu: Support update net's bootindex
  qemu: Support set bootindex to 0 to cancel bootindex setting
  test: add a test for bootIndex = 0 provided by the user

* add a test for bootindex = 0 provided by user
