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 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.

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. |
