[Qemu-devel] [PATCH v13 0/8] pv event interface between host and guest |
Date: |

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
