[Qemu-devel] [Bug 1037675] Re: Guest Kernel Panic if using "-cpu host" in qemu-kvm 1.1.1 |

I have the same issue, but not on hardened.
Tried for 1-2 hours to send the output to serial console but failed.
The text below is what I posted at
https://bugs.gentoo.org/show_bug.cgi?id=431640#c8:
###############
Same issue here (same screenshot with qemu-kvm-1.1.1-r1), but not on hardened.
Happens with 1.1.1-r3 with a different panic message (not the one
mentioned in bug #431444)
I fail miserably at "sending output to serial console or file", if anyone
would help me there I could provide the entire output of the kernel panic.
Below is what I've found out to far:
(Tests with qemu-kvm-1.1.1-r1)
Analysis:
=========
Happens with the following LiveCDs:
- Fedora-17-x86_64-netinst.iso: uname -r = 3.3.4-5.fc17.x86_64; image:
/LiveOS/squashfs.img
- pentoo-x86_64-2012.0_beta1.7.iso: uname -r = 3.4.2-pentoo; image:
image.squashfs
Does not happen with:
- pentoo-x86_64-2009.0.iso: uname -r = 2.6.31-pentoo-r3; image: image.squashfs
- (Gentoo) install-amd64-minimal-20120621.iso: uname -r = 3.2.12-gentoo;
image.squashfs
- systemrescuecd-x86-2.8.1.iso (64bit kernel): uname -r = 3.2.23-std281-amd64:
sysrcd.dat
Tried installing qemu-kvm-1.1.1-r1 without the 2 patches, no difference.
Guess:
======
This seems to happen only with newer guest-kernels (on newer CPUs).
