Unfortunately at least for PC, boot order is exposed in fw cfg which can not change while guest is running. I suspect we need to change how we report boot order to guests. While we are at it, maybe we can fix the silly bootindex convention: I think people really want to specify boot *order*, not boot index. > hmp.c | 11 ++++++++++ > 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 | 53 +++++++++++++++++++++++++++++++++++++++------ > 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 | 16 ++++++++++++++ > qmp.c | 14 ++++++++++++ > vl.c | 55 > +++++++++++++++++++++++++++++++++++++++++++++++ > 23 files changed, 179 insertions(+), 7 deletions(-) > > -- > 1.7.12.4 >
