Hi,
I have AMD servers running CentOS 6.10 as KVM host and on it guests running CentOS 7.5.
Since the latest kernel update on CentOS 6.10, kernel-2.6.32-754.2.1.el6.x86_64, I can't boot the CentOS 7.5 guests with kernel-3.10.0-862.6.3.el7.x86_64 anymore.
Reverting CentOS 6.10 host to kernel-2.6.32-754.el6.x86_64 fixes the problem.
Screendump of the panic is attached, not very helpful I guess.
The CPU models where I could test it are:
cpu family : 15 model : 65 model name : Dual-Core AMD Opteron(tm) Processor 2218 stepping : 3
cpu family : 16 model : 6 model name : AMD Athlon(tm) II Neo N36L Dual-Core Processor stepping : 3
Didn't test on newer CPU family yet.
I'm wondering, does someone see the same issue? Does it not happen on Intel CPUs?
Thanks for any insight.
Regards, Simon

I didn't know attachments are stripped by the list.
Here is the bugreport:
https://bugs.centos.org/view.php?id=15067
My feeling is that the recent Intel fixes/workarounds have broken it here for AMD systems :(

I had to set my CPU type to opteron_g3 instead of opteron_g5 for some machines on an AMD server.

This was the bug I hit ... not your scenario .. but who knows:

Looks like your scenario was really quite different.
BTW, I've just tested with kernel-3.10.0-862.9.1.el7.x86_64 on the CentOS 7 guest and it still crashes the same way.
