Hi,
on an embedded PC (500MHz AMD Geode), we recently tried
to upgrade the kernel. The original version was 2.6.27, the new
ones were 3.3.x and 3.7.x. With the same userspace (a GTK based
GUI constantly querying daemons handling different pieces of
hardware over serial ports), we noticed that

Hi Dave
Sorry, I was busy reworking the HIDP layer. I finally got time to
continue my work on this again. See below:

We can know the guest is panicked when the guest runs on xen.
But we do not have such feature on kvm.
Another purpose of this feature is: management app(for example:
libvirt) can do auto dump when the guest is panicked. If management
app does not do auto dump, the guest's user can do dump by hand
If the target is x86/x86_64, the guest's kernel will write 0x01 to the
port KVM_PV_EVENT_PORT when it is panciked. This patch introduces a new
qom device kvm_pv_ioport to listen this I/O port, and deal with panicked
event according to panicked_action's value. The possible actions are:

The guest should run after resetting it, but it does not run if its
old state is RUN_STATE_INTERNAL_ERROR or RUN_STATE_PAUSED.
We don't set runstate to RUN_STATE_PAUSED when resetting the guest,
so the runstate will be changed from RUN_STATE_INTERNAL_ERROR or
RUN_STATE_PAUSED
update kernel headers to add pv event macros.

This patch enables preservation of cpu runstate during save/load vm.
So when a vm is restored from snapshot, the cpu runstate is restored,
too.
See following example:
# save two vms: one is running, the other is paused
(qemu) info status
VM status: running
(qemu) savevm running
(qemu) stop
This event will be emited when the guest is panicked.

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

When building ncurses with --with-termlib several symbols get moved from
libncurses.so to libtinfo.so. Thus when linking with libncurses.so, one
additionally needs to link with libtinfo.so. Ncurses provides a config script
(ncurses5-config) to assist finding ncurses.

Thanks. Interesting - this suggests an unexpectedly high hit rate.
