Hello, I built 4.9.155 for both el6 and el7, you can test them here: [1]

It works fine for me so far on el6, I'll update my pull request
later on
GitHub with this version. [root@node-tmp1 ~]# cat /proc/version Linux version 4.9.155-34.el6.x86_64 ([3]

Great, thanks a lot! I'll give it a go.
With initial testing seems to work OK for me! Meanwhile upstream kernel is up to v4.9.161, so let's update the sig-virt kernel to that version..
Karl: Can you prepare a PR?
Thanks,

I built 4.9.161, works for me on el6:
[root@node-tmp1 ~]# cat /proc/version Linux version 4.9.161-34.el6.x86_64 (mockbuild@build.aerisnetwork.net) (gcc version 7.3.1 20180303 (Red Hat 7.3.1-5) (GCC) ) #1 SMP Wed Feb 27 09:48:40 EST 2019
Only one strange thing, I had to run grub-install because Grub couldn't find root device after reboot, not sure this has something to do with the kernel upgrade. Kernel 4.9.161 doesn't have the patch for CVE-2019-8912 yet so we might wait until it get released.
I updated my PR: https://github.com/CentOS-virt7/xen-kernel/pull/18
https://repo.aerisnetwork.com/archive/kernel-4.9.161-34.el6.x86_64.rpm https://repo.aerisnetwork.com/archive/kernel-4.9.161-34.el7.x86_64.rpm
Anthony Perard already tried to build my PR on the CBS but he was not able to enable the SCL repo ( http://mirror.centos.org/centos/$releasever/sclo/$basearch/rh/) to get devtoolset-7. We might need to get help from centos-devel.

Hello everyone, Some of you might remember discussions earlier in 2017 (huh, longtime
ago) on centos-virt list about Linux kernel tty/ldisc relatedbug, which
caused Xen dom0 kernel crashes for some people (and also moreeasy to
trigger crashes on other arches, like on hp pa-risc), but the bugwas
difficult to reproduce for others/most people. Fix for this issue was merged to centos virt-sig Linux 4.9.48-29kernel
earlier in 2017, but reverted/deleted in 4.9.75-30 due toproblems with
the patch. The patch in question was also merged to upstream Linux kernel, and later reverted there aswell. But now finally the issue has been resolved in upstream Linux,and the
patches have been already backported to Linux 4.9.152 longtermstable
kernel. Changelog: [5]https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.9.152 You can find the tty/ldisc patches there. So I propose we build the latest 4.9.155 kernel for CentOSvirt-sig for
centos6 and centos7. Thanks, -- Pasi
