<p>No, don't get that confused. As of lately, Fedora 25 has updated
to kernel 4.9.11 as well. But this is just coincidence. This is
not the Xen4CentOS Dom0 testing-kernel, but the package from
Fedora's update repos. That testing kernel is used on the guest
along with Xen4CentOS Xen hypervisor packages to make a Xen4CentOS
(7) virtualization host as guest on kvm.<br>
</p>
<p>I just happen to run my workstation with Fedora+KVM. For any
virtualization testing, I use nested virt and create Xen
virtualization hosts as kvm guests for testing puposes. <br>

this kernel is also for KVM hosts? If not, will be? I use elrepo
now...<br>

Hi<br>
<br>
So far, I did some preliminary testing using nested virt:<br>
<br>
host(L0): Fedora 25, kernel-4.9.11-200, kvm+qemu<br>
<br>
Guest(L1): CentOS 7 Xen-4.6.3-7, kernel-4.9.11-22<br>
<br>
So far, at least the L1 setup had no issues. I'll need to pull
L1 <br>
guest-storage from backup to test some L2 guests.<br>
<br>
Likewise, I try to allocate two blades at work for tests on
real <br>
metal. Our standard-tests include starting CentOS-5/6/7 guests
and <br>
migrate them around. I hope to get this done next week, but I
need <br>
company approval for that, which seems doable, as we use
Xen4CentOS in <br>
production :)<br>
Running diverse CentOS versions and some Windows Server guests
and <br>
being capable of migrating the whole shebang around from
machine to <br>
machine is our daily use case. That includes PV, HVM+PV and
PVHVM <br>
guest types, which is pretty comprehensive to me.<br>
<br>
Let me know, if you are interested in more detailed <br>
settings/setup/tests and I will see, what I can run.<br>
<br>
Rest assured, that this work is much needed and appreciated.
We run <br>
almost 1000 virtual machines on about 70 blades using
Xen4CentOS since <br>
day 1. This new kernel gives us the latest drivers in Dom0,
something <br>
which is highly desired, as we are seeing issues occasionally,
like <br>
bnx2x oops-ing on broadcom 10G interfaces.<br>
<br>
Regards,<br>
Thomas<br>

I have pushed some new kernels and linux-firmware packages
to the<br>
xen-testing repos for both CentOS-6 and CentOS-7. The
CentOS-7 packages<br>
may take a few hours to make it to the repo.<br>
<br>
The CentOS-6 repo also contains a newer xfsprogs as that
is required<br>
with newer kernels

<br>
This kernel (and supplementary xfsprogs, linux-firmware)
are scheduled<br>
to be the replacements for the 3.18.x LTS tree that has
gone EOL from<br>
Kernel.org. We can maintain the 4.9 LTS tree until
January 2019<br>
(<a class="moz-txt-link-freetext" href="https://www.kernel.org/category/releases.html">https://www.kernel.org/category/releases.html</a>).<br>
<br>
We have added in blktap2 support to this kernel, please
test that<br>
functionality if you need it, it seems to be working to
me.<br>
<br>
We really need people to test this kernel and associated
packages<br>
thoroughly so we can find and fix issues before release.<br>
<br>
Please post any issues or questions on this list.<br>

OK, just tagged 4.9.13-22.el7 (and .el6) to the testing
repos for xen on<br>
c6 and c7 as this fixes the new dccp kernel issue.<br>
<br>
Only have one person reporting good tests so far. We need
more testing<br>
or we risk to breaking people's systems when we release
later.<br>
