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

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. diff to v1: * add a bool bootIndexSpecified in device info to indicates that the bootorder of the device can be set. * use boot order = '0' to cancel the previous bootorder instead of '-1' Jiang Jiacheng (7): qemu: Introduce qemuDomainChangeBootIndex API qemu: Add bootIndexSpecified and support set bootIndex to '0' qemu: Introduce qemuCheckBootIndex and qemuChangeDiskBootIndex API qemu: Support update disk's bootindex qemu: Support update net's bootindex qemu: Support add bootindex = 0 to boothash when its bootIndexSpecified is true qemu: Reserve bootIndexSpecified when update device src/conf/device_conf.h | 3 + src/conf/domain_conf.c | 9 ++- src/conf/domain_postparse.c | 8 +- src/qemu/qemu_conf.c | 140 +++++++++++++++++++++++++++++++++++ src/qemu/qemu_conf.h | 16 ++++ src/qemu/qemu_domain.c | 3 +- src/qemu/qemu_driver.c | 35 +++++++++ src/qemu/qemu_hotplug.c | 17 +++-- src/qemu/qemu_monitor.c | 20 +++++ src/qemu/qemu_monitor.h | 6 ++ src/qemu/qemu_monitor_json.c | 33 +++++++++ src/qemu/qemu_monitor_json.h | 6 ++ 12 files changed, 286 insertions(+), 10 deletions(-) -- 2.33.0
