[Qemu-devel] [Bug 1037675] Re: Guest Kernel Panic if using "-cpu host" in qemu-kvm 1.1.1
I am seeing more or less the same thing. I am trying to boot Puppy Linux from Gentoo with qemu-kvm-1.1.1-r3 and gentoo-sources-3.6.0. Interestingly, I also found that AROS crashed when using "-cpu host" but I initially chalked that up to AROS being flakey - perhaps not. Obviously I can't enable those kernel options in AROS and I don't want to have to build my own Puppy kernel. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1037675 Title: Guest Kernel Panic if using "-cpu host" in qemu-kvm 1.1.1 Status in QEMU: New 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.

thx for the patience, i am currently very busy, therefore this took a bit longer than it was planed: - using a non hardened kernel (gentoo-sources-3.3.8) does not resolve the issue therefore i need to use the serial console, which is somewhat new to me. i will do this as soon as i find some time. i am still on it ;) -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1037675 Title: Guest Kernel Panic if using "-cpu host" in qemu-kvm 1.1.1 Status in QEMU: New 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.

I have the same issue, but not on hardened. Tried for 1-2 hours to send the output to serial console but failed.

sorry for the not very usefull information i provides above. i will try to reproduce the the failure with a vailla kernel (host) in a few days. currently the server is in use and cannot be restarted. the kernel panic was in the guest (thought this is clear by "my vm panic").

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.
