This series implements a new interface, kvm pv event, to notify host when some events happen in guest. Right now there is one supported event: guest panic.
Also, the cpu runstate is preserved during save/load vm and migration. Thus, if vm is panicked during migration, we can still know it by quring the status of vm in destination host when migration completes.
v12: http://lists.nongnu.org/archive/html/qemu-devel/2013-01/msg04120.html
changes from v12: - no DO_UPCASE - the interface is only for x86 now - request 4 bytes io range(hw/kvm_pv_event.c) - rebase to the latest tree
Hu Tao (7): save/load cpu runstate update kernel headers add a new runstate: RUN_STATE_GUEST_PANICKED add a new qevent: QEVENT_GUEST_PANICKED introduce a new qom device to deal with panicked event allower the user to disable pv event support pv event: add document to describe the usage
Wen Congyang (1): start vm after resetting it
