Here's v4 of the ioeventfd for s390 patch set.
The most interesting change is the addition of MST's cookie patch,
which enhances the virtio-ccw notify hypercall for future performance
optimizations. This patch should go in for 3.9.
I'd love to see the other patches in 3.9 as well; but I wouldn't

ciao Vasiliy,
What is the best for some small vms?
2-Xeon E5520 or 1- E5-2620
Second have more performance but only one. First have less perfarmance..
What is the best - performance of single cpu or count of cpus with
less performance?
usually the bottleneck is the storage, not the cpu power

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 qurin
From: Wen Congyang
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
The guest will be in this state when it is panicked.

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:
1. emit QEVEN
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

OK we talked about this a while ago, here's
a summary and some proposals:
At the moment, virtio PCI uses IO BARs for all accesses.
The reason for IO use is the cost of different VM exit types
of transactions and their emulation on KVM on x86
(it would be trivial to use memory BARs on non x86 platf
