Bug Description
After Upgrading to qemu-kvm-1.1.1-r1 from version 1.0.1-r1 my virtual machines (running gentoo linux) panic at intel_pmu_init. (detailed information including stacktrace are in the uploaded screenshot). When i remove the "-cpu host" option, the system starts normally.
the command line from whicht the system is bootet:
qemu-kvm -vnc :7 -usbdevice tablet -daemonize -m 256 -drive file=/data/
also reported on gentoo bug tracker (with some more details of the host): https:/
First of all, your kernel panic screenshot is incomplete: it lacks the most important information which were scrolled off the (virtual) screen. Please enable serial console and capture whole OOPs in a text form.
Second, it isn't clear whenever this is HOST kernel panic or GUEST kernel panic. I assume it is guest.
Third, you nevrer said which guest (kernel) it is.
And forth, gentoo is very well known for breaking qemu-kvm by their "hardened" patches. Disable the hardening and retry.
