Hi I had a KVM crash today with WinXP Pro SP3 32bit on kvm-88 + kernel 2.6.30.6 (modules from kernel). ------------[ cut here ]------------ WARNING: at arch/x86/kvm/x86.c:204 kvm_queue_exception_e+0x6b/0x80 [kvm]() Hardware name: Latitude D520 Modules linked in: ipv6 i915 drm i2c_algo_bit rfcomm sco bridge stp llc bnep l2cap btusb bluetooth fan usbhid hid fuse snd_seq_dummy tun snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device kvm_intel kvm snd_pcm_oss joydev snd_hda_codec_idt snd_mixer_oss ohci1394 ieee1394 snd_hda_intel arc4 snd_hda_codec snd_hwdep ecb snd_pcm yenta_socket rsrc_nonstatic dell_laptop snd_timer snd soundcore snd_page_alloc uhci_hcd psmouse video thermal output ac iTCO_wdt iTCO_vendor_support wmi processor button iwl3945 ehci_hcd battery usbcore dcdbas i2c_i801 i2c_core intel_agp sg iwlcore rfkill mac80211 led_class agpgart serio_raw evdev cfg80211 slhc b44 ssb pcmcia pcmcia_core mii rtc_cmos rtc_core rtc_lib ext3 jbd mbcache aes_i586 aes_generic xts gf128mul dm_crypt dm_mod sd_mod sr_mod cdrom ata_piix ata_generic pata_acpi libata scsi_mod Pid: 4238, comm: qemu-kvm Not tainted 2.6.30-ARCH #1 Call Trace: [<c013b26a>] ? warn_slowpath_common+0x7a/0xc0 [<f8a3451b>] ? kvm_queue_exception_e+0x6b/0x80 [kvm] [<c013b2d0>] ? warn_slowpath_null+0x20/0x40 [<f8a3451b>] ? kvm_queue_exception_e+0x6b/0x80 [kvm] [<f8a35927>] ? kvm_task_switch+0x277/0xc60 [kvm] [<f8a3d842>] ? mmu_sync_children+0x182/0x340 [kvm] [<f8a42015>] ? x86_emulate_insn+0x1895/0x3cb0 [kvm] [<f8a3ff96>] ? x86_decode_insn+0x686/0xd50 [kvm] [<f8a654be>] ? vmx_fpu_deactivate+0x4e/0x70 [kvm_intel] [<f8a66b61>] ? handle_task_switch+0x31/0xc0 [kvm_intel] [<f8a67161>] ? kvm_handle_exit+0xf1/0x200 [kvm_intel] [<c012a5a4>] ? kunmap_atomic+0x84/0xb0 [<c012a55c>] ? kunmap_atomic+0x3c/0xb0 [<f8a34dcd>] ? kvm_arch_vcpu_ioctl_run+0x34d/0xaf0 [kvm] [<f8a2ab5e>] ? kvm_vcpu_ioctl+0x45e/0x7f0 [kvm] [<c0166dba>] ? futex_wake+0xfa/0x110 [<f8a2a700>] ? kvm_vcpu_ioctl+0x0/0x7f0 [kvm] [<c01dfcb2>] ? vfs_ioctl+0x22/0xa0 [<c01dfdb9>] ? do_vfs_ioctl+0x89/0x5a0 [<c0141bca>] ? irq_exit+0x3a/0x90 [<c01688fa>] ? sys_futex+0xca/0x160 [<c01e035e>] ? sys_ioctl+0x8e/0xb0 [<c0103cb3>] ? sysenter_do_call+0x12/0x28 ---[ end trace 82bf054de8a6387e ]--- Misc info: -- The Blue Screen Of Death gave the following error: *** STOP: 0x0000008E (0xC000001D, 0xF7A48D3E, 0xF7C5ECC0, 0x00000000) *** processr.sys - Address F7A48D3E base at F7A47000, DateStamp 48025181 -- Startup command: qemu-kvm -usbdevice tablet -net nic,macaddr=52:55:00:00:00:01,model=rtl8139 -net tap,ifname=tap0 -vnc :1 -smp 2 -m 1024 -cdrom /home/kenni/images/NETKVM-20081229.iso -hda /data/virtualization/winxp.img -boot c -localtime -daemonize -monitor unix:/var/run/kvm/01_winxp.socket,server,nowait -- $ cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 15 model name : Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz stepping : 6 cpu MHz : 1995.143 cache size : 4096 KB physical id : 0 siblings : 2 core id : 0 cpu cores : 2 apicid : 0 initial apicid : 0 fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 10 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm constant_tsc arch_perfmon pebs bts pni dtes64 monitor ds_cpl vmx est tm2 ssse3 cx16 xtpr pdcm lahf_lm tpr_shadow bogomips : 3991.54 clflush size : 64 power management: <snip> -- $ uname -a Linux D520 2.6.30-ARCH #1 SMP PREEMPT Wed Sep 9 12:37:32 UTC 2009 i686 Intel(R) Core(TM)2 CPU T7200 @ 2.00GHz GenuineIntel GNU/Linux -- I don't suppose that this is enough information for you to identify the issue? As I haven't had this crash before, I don't know if I'll see it again...can I do something to collect better debugging information in the future? Perhaps enable kernel memory dump in Windows or something else?
