Hi Paolo,

I was able to test your patches in our s390 environment. I don't see the qemu crashes anymore which I noticed before.

Testing a guest running high stress I/O workload, without iothreads does show a delay in guest response time. But running

the same test with iothreads seems to solve the issue.

Tested-by : Farhan Ali <address@hidden>


Thank you

Farhan
