Description of problem: Trying to install a CentOS 5 from CDROM into a KVM virtual machine causes host computer to instantly reboot. Version-Release number of selected component (if applicable): [rms@roque ~]$ cat /etc/fedora-release Fedora release 12 (Constantine) [rms@roque ~]$ rpm -q kernel kernel-2.6.32.9-67.fc12.x86_64 [rms@roque ~]$ rpm -q qemu-kvm qemu-kvm-0.11.0-13.fc12.x86_64 How reproducible: Always. Steps to Reproduce: 1. sudo qemu-kvm -m 512 -hda centos5.img -cdrom /dev/cdrom -boot d Actual results: Guest console window opens, but a few seconds later there's an instant reboot of the host computer. Expected results: Running a VM, also without hurting the host OS.
Merely running "sudo qemu-kvm -m 512 -hda centos5.img" is also enough to to fire this bug.
This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '12'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 12's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 12 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Needs a BIOS update after all, and I had forgotten about this F12 bug. Related entry for F13 is, with the appropriate bug fix (BIOS update) https://bugzilla.redhat.com/show_bug.cgi?id=588151
