Category: None Group: None >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: Jiajun Xu (jiajun) Assigned to: Nobody/Anonymous (nobody) Summary: Booting IA32e Windows guest meets BSOD Initial Comment: With latest commit, kvm.git 77d0a44d2393f43836fd38c235dfda2de4c4630a and userspace.git d32aaf6d02d102855e5d8d1e23f0c55ca214e871, IA32e Windows guest(including Windows XP, Windows 2003, Windows Vista) fails to boot. Guest will meet BSOD when booting, error code 0x0000000A(IRQL_NOT_LESS_OR_EQUAL). Previous commit, kvm.git a509fff8ed134115f2fd413e92a92cddc1709a5f userspace.git 42621e776ac3a12930c3fec19c60e68e563df4cc has no such issue. ---------------------------------------------------------------------- >Comment By: Jiajun Xu (jiajun) Date: 2008-10-25 08:49 Message: The issue is fixed with kvm.git b33b7347236abd6033e52af2d4296e044e6d67dd. ---------------------------------------------------------------------- Comment By: Jan Kiszka (kiszka) Date: 2008-10-15 06:04 Message: Problem finally reproduced here, I had this patch applied: http://permalink.gmane.org/gmane.comp.emulators.kvm.devel/22635. That one cures the the issue, but I think it papers over a small (but fatal) incorrectness of 77d0a44d2393f43836fd38c235dfda2de4c4630a. Will dig deeper. ---------------------------------------------------------------------- Comment By: Jan Kiszka (kiszka) Date: 2008-10-12 09:32 Message: OK, this (the NMI watchdog) now likely became a regression of -77. I tried reproducing it with a Windows Server 2003 R2 (64-bit), but without success. Can you describe your scenario in more details? Vanilla Windows installation? Which qemu command line switches precisely? Anything else I may need to know to reproduce? Further tests: Does http://permalink.gmane.org/gmane.comp.emulators.kvm.devel/22635 change the situation? What does http://permalink.gmane.org/gmane.comp.emulators.kvm.devel/22634 make kvm report to the kernel log? ---------------------------------------------------------------------- Comment By: Jiajun Xu (jiajun) Date: 2008-10-10 07:09 Message: We find that kernel.git cbb44eaa2d961f1eb975b52c7be1c82178b3c580 introduces the issue first. With kernel.git ba8ab77ebfba9898764c39bc2f00540a5a67a1e9, windows guest can boot up successfully. ---------------------------------------------------------------------- Comment By: Jiajun Xu (jiajun) Date: 2008-10-06 07:53 Message: OK. I will try to find the causing. with no-kvm-irqchip or no-kvm-pit, we did not meet such issue. ---------------------------------------------------------------------- Comment By: Jan Kiszka (kiszka) Date: 2008-10-06 07:38 Message: Can you try to narrow down the causing patches, specifically on the kernel side? I assume you run with in-kernel irqchip, right? ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=893831&aid=2149609&group_id=180599
