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.
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.

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

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.

Thomas

I have pushed some new kernels and linux-firmware packages
to the
xen-testing repos for both CentOS-6 and CentOS-7. The
CentOS-7 packages
may take a few hours to make it to the repo.
The CentOS-6 repo also contains a newer xfsprogs as that
is required
with newer kernels
(https://bugzilla.redhat.com/show_bug.cgi?id=1314605).
This kernel (and supplementary xfsprogs, linux-firmware)
are scheduled
to be the replacements for the 3.18.x LTS tree that has
gone EOL from
Kernel.org. We can maintain the 4.9 LTS tree until
January 2019
(https://www.kernel.org/category/releases.html).
We have added in blktap2 support to this kernel, please
test that
functionality if you need it, it seems to be working to
me.
We really need people to test this kernel and associated
packages
thoroughly so we can find and fix issues before release.
Please post any issues or questions on this list.
OK, just tagged 4.9.13-22.el7 (and .el6) to the testing
repos for xen on
c6 and c7 as this fixes the new dccp kernel issue.
Only have one person reporting good tests so far. We need
more testing
or we risk to breaking people's systems when we release
later.
