From: Gonglei <arei.gong...@huawei.com> Sometimes, we want to modify boot order of a guest, but no need to shutdown it. We can call dynamic changing bootindex of a guest, which can be assured taking effect just after the guest rebooting.
For example, in P2V scene, we boot a guest and then attach a new system disk, for copying some thing. We want to assign the new disk as the booting disk, which means its bootindex=1. Different nics can be assigen different bootindex dynamically also make sense. The patchsets add one qmp interface, and add an fw_cfg_machine_reset() to achieve it. Please review, Thanks. Gonglei (6): bootindex: add {del,modify}_boot_device_path function fw_cfg: add fw_cfg_machine_reset function bootindex: delete bootindex when device is removed qmp: add set-bootindex command qemu-monitor: HMP set-bootindex wrapper spapr: fix possible memory leak hmp-commands.hx | 15 +++++++++++++ hmp.c | 13 +++++++++++ hmp.h | 1 + hw/block/virtio-blk.c | 1 + hw/i386/kvm/pci-assign.c | 1 + hw/misc/vfio.c | 1 + hw/net/e1000.c | 1 + hw/net/eepro100.c | 1 + hw/net/ne2000.c | 1 + hw/net/rtl8139.c | 1 + hw/net/virtio-net.c | 1 + hw/net/vmxnet3.c | 1 + hw/nvram/fw_cfg.c | 54 ++++++++++++++++++++++++++++++++++++++------ hw/ppc/spapr.c | 1 + hw/scsi/scsi-generic.c | 1 + hw/usb/dev-network.c | 1 + hw/usb/host-libusb.c | 1 + hw/usb/redirect.c | 1 + include/hw/nvram/fw_cfg.h | 2 ++ include/sysemu/sysemu.h | 4 ++++ qapi-schema.json | 16 +++++++++++++ qmp-commands.hx | 24 ++++++++++++++++++++ qmp.c | 17 ++++++++++++++ vl.c | 57 +++++++++++++++++++++++++++++++++++++++++++++++ 24 files changed, 210 insertions(+), 7 deletions(-) -- 1.7.12.4
