Updating my CentOS 6.8 Xen server with new 4.9.13 kernel yields a kernel boot message of a few like "APIC ID MISMATCH" and the system reboots immediately without any other bits of info. This is on a Dell R710 with 64GB RAM and 2x 6-core Intel CPU's. As an additional test, I installed and attempted to run the current "testing" kernel of 4.9.16 with the exact same results.
Anyone have an idea? The 3.18.x series runs without issue of course.
Thanks

Try this kernel (the noarch kernel-doc is not done yet), but that is not a required package:
https://people.centos.org/hughesjr/4.9.16/x86_64/
Let me know if that works or not .. we can try adjusting some other config settings.
Don't worry about the centos.plus dist tag .. that will change when we subnit it via the regular process.
Thanks, Johnny Hughes

I think the APIC ID MISMATCH is an expected and ignorable error .. see:
https://patchwork.kernel.org/patch/9539933/
I applied that patch and I am building a 4.9.16-23 right now, I 'll publish it when it finishes. Maybe with the error gone we can get a better error in the console.

Edit grub's entry and add "noreboot" to your xen parameters, maybe when the kernel panicks xen detects it and automatically reboots it.

Edit grub's entry and add "noreboot" to your xen parameters, maybe when the kernel panicks xen detects it and automatically reboots it.
"noreboot" grub.conf option still produced nothing other than a flashing cursor on the top left. Also, neither num-lock nor caps-lock respond at this time...

Try removing "rhgb" and "quiet" from your boot options as well.

That sounds like a compiler problem, since I think the C6 and C7 kernels are built from the same source.

The mystery gets more interesting... I now have a CentOS 7.3 Dell R710 server doing the exact same thing of rebooting immediately after the Xen kernel load. Just to note this is a second system and not just the first system with an update. I hope I'm not introducing something odd. They only "interesting" thing I have done for historical reasons is to change the following /etc/sysconfig/grub line: GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=6G,max:8G cpuinfo com1=115200,8n1 console=com1,tty loglvl=all guest_loglvl=all" But I've done that on other servers without issue. In fact I have a Dell R710 that DOES work with CentOS 7 and the new kernel... so confused.

I ran into this also.
back up to an older kernel. At least that was my solution till a kernel came out that would boot.
It seems that some kernel builds are not friendly to xen.

Maybe the BIOS versions are different on the two machines if they are the same models. Different disc controllers or modes set up? Different NICs or other add on cards?

The mystery gets more interesting... I now have a CentOS 7.3 Dell R710 server doing the exact same thing of rebooting immediately after the Xen kernel load. Just to note this is a second system and not just the first system with an update. I hope I'm not introducing something odd. They only "interesting" thing I have done for historical reasons is to change the following /etc/sysconfig/grub line: GRUB_CMDLINE_XEN_DEFAULT="dom0_mem=6G,max:8G cpuinfo com1=115200,8n1 console=com1,tty loglvl=all guest_loglvl=all" But I've done that on other servers without issue. In fact I have a Dell R710 that DOES work with CentOS 7 and the new kernel... so confused.
PJ,
Thanks for your testing and report. Would you mind reporting this on xen-devel? If there's actually a bug in the Linux 4.9.x on Xen boot path on your box, I don't think Johnny or I are going to be able to help you debug it. :-)

OK, I have a new CentOS-6 4.9.20-26 kernel here for testing:
https://people.centos.org/hughesjr/4.9.16/6/x86_64/
I am building the el7 one right now as well, it will be at:
https://people.centos.org/hughesjr/4.9.16/7/x86_64/
George and I found some issues with the 4.9.x config files for the xen kernel. Hopefully this one is much more stable as it has many changes from the fedora/rhel type configs now (what is built into the kernel, what is loaded as a kernel module, etc.)
Please test these kernels so we can get them released.
Thanks, Johnny Hughes

CentOS-6 4.9.20-26 kernel exhibits the same constant kernel-start-then-reboot issue when booting under the "CentOS Linux, with Xen hypervisor" grub2 menu option. However, it *does* properly boot under the "CentOS Linux (4.9.20-25.el7.x86_64) 7 (Core)" grub2 menu option!
A semi-close look at the /etc/grub2.cfg yields no discernible difference between a properly functional Dell R620 and the non-properly functioning Dell R710.
Sorry, I had been distracted with other issues and have not yet submitted information to the xen-devel group yet.
Thanks PJ
So interesting and challenging too, IT seems to Xen compatibility to Dell board BIOS related.
I have Dell R710 and R7200 with same Xen version, but the outcome is completely different, that R720 is slow in performance and reboot too.

I am having no similar issues with several Dell Proliant DL160p's and CentOS 6. They are either G5 or G6, I don't recall which.

I've not gotten any bites from my posting on the xen-devel mailing list. Here is the only one to-date: https://lists.xen.org/archives/html/xen-devel/2017-04/msg01069.html
From that email, there needs to be some hypervisor messages.
Does anyone know how to produce the hypervisor messages? I've already removed the rhgb and quiet options from the boot.
Thanks PJ

I spoke too soon. To get more information: Please see https://wiki.xenproject.org/wiki/Reporting_Bugs_against_Xen_Project and https://wiki.xenproject.org/wiki/Xen_Serial_Console or alternatively at least add "vga=keep".
