[CentOS-virt] New 4.9.11-22 kernels and linux-firmware packages to test in xen-testing for CentOS-6 and CentOS-7

[T.Weyergraf]

Hi

So far, I did some preliminary testing using nested virt:

host(L0): Fedora 25, kernel-4.9.11-200, kvm+qemu

Guest(L1): CentOS 7 Xen-4.6.3-7, kernel-4.9.11-22

So far, at least the L1 setup had no issues. I'll need to pull L1 
guest-storage from backup to test some L2 guests.

Likewise, I try to allocate two blades at work for tests on real metal. 
Our standard-tests include starting CentOS-5/6/7 guests and migrate them 
around. I hope to get this done next week, but I need company approval 
for that, which seems doable, as we use Xen4CentOS in production :)
Running diverse CentOS versions and some Windows Server guests and being 
capable of migrating the whole shebang around from machine to machine is 
our daily use case. That includes PV, HVM+PV and PVHVM guest types, 
which is pretty comprehensive to me.

Let me know, if you are interested in more detailed settings/setup/tests 
and I will see, what I can run.

Rest assured, that this work is much needed and appreciated. We run 
almost 1000 virtual machines on about 70 blades using Xen4CentOS since 
day 1. This new kernel gives us the latest drivers in Dom0, something 
which is highly desired, as we are seeing issues occasionally, like 
bnx2x oops-ing on broadcom 10G interfaces.

Regards,
Thomas
