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

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

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