So I booted into my RHEL5.3 VM, and force installed the PAE kernel, and it also fails to boot. In fact, all you see are the GRUB messages: Booting command-list root (hd0,0) Filesystem type is ext2fs, partition type 0x83 kernel /vmlinuz-2.6.18-128.el5PAE ro root=/dev/VolGroup00/LogVol00 console=ttyS 0 [Linux-bzImage, setup=0x1e00, size=0x1bb6f4] initrd /initrd-2.6.18-128.el5PAE.img [Linux-initrd @ 0xfcd1000, 0x30e286 bytes] And nothing else is printed from the VM. Last bit of info I was able to get was while booting with 'earlyprintk=ttyS0'. It gives a bit more output: Initializing cgroup subsys cpuset Initializing cgroup subsys cpu Linux version 2.6.27.19-5-pae (geeko@buildhost) (gcc version 4.3.2 [gcc-4_3-branch revision 141291] (SUSE Linux) ) #1 SMP 2009-02-28 04:40:21 +0100 PAT WC disabled due to known CPU erratum.

If this is the case, it should be fixed by recent patches of cpuid trimming. Please try a newer version of qemu. http://koji.fedoraproject.org/koji/buildinfo?buildID=104657 Updating to: qemu-system-x86-0.10.5-2.fc11.i586 qemu-img-0.10.5-2.fc11.i586 qemu-common-0.10.5-2.fc11.i586 qemu-system-ppc-0.10.5-2.fc11.i586 does get the PAE guests running w/o issues. Thanks for testing, Joel qemu-0.10.5-2.fc11 has been pushed to the Fedora 11 stable repository. If problems still persist, please make note of it in this bug report. |
Created attachment 347019 [details] screenshot of the full boot of the SLES11 32bit PAE VM Description of problem: In Fedora 11 32bit during installation of SLES11 32bit under Qemu/KVM, it uses the kernel-default kernel. Somewhere during the install, the installer detects that it is running on PAE capable hardware so it decides to install the PAE kernel. On first boot, it tries to boot the PAE kernel and hangs with the last message being: Probing EDD (edd=off to disable)... ok If instead during installation you force it to not install the PAE kernel, then all is fine. Version-Release number of selected component (if applicable): qemu-common-0.10.4-4.fc11.i586 qemu-img-0.10.4-4.fc11.i586 qemu-system-ppc-0.10.4-4.fc11.i586 qemu-system-x86-0.10.4-4.fc11.i586 kernel-2.6.29.4-167.fc11.i586 How reproducible: Every single time. Steps to Reproduce: 1. Install SLES11 32bit on Fedora 11 with KVM enabled. 2. After install, try to boot the SLES11 VM. 3. Watch it fail. Actual results: Hang early on boot. Expected results: No hang at all. Additional info: This is on a Thinkpad T61 with Intel(R) Core(TM)2 Duo CPU T7300 @ 2.00GHz
