Strangely I got the same problem one or two hours ago. Here are some info about the host: - Distribution: Debian - Architecture: x86_64 - Kernel: 2.6.22-2 - CPU: Intel Core 2 Q6600 - KVM 48 The system is running 10 KVM guests and the operating systems are BSD, Linux, Hurd, GNU/kFreeBSD. Only one of the two GNU/kFreeBSD amd64 guests crashed, the others are still running fine. It was under heavy load (building a glibc). And the dmesg log: ------------[ cut here ]------------ kernel BUG at /usr/local/src/kvm-48/kernel/mmu.c:307! invalid opcode: 0000 [1] SMP CPU 3 Modules linked in: usb_storage kvm_intel kvm cpufreq_userspace nfs nfsd exportfs lockd nfs_acl sunrpc ppdev lp button ac battery xt_mark xt_MARK ipt_REDIRECT ipt_REJECT ipt_recent xt_state ipt_TOS xt_tcpudp ipt_LOG xt_limit iptable_mangle iptable_nat nf_conntrack_ipv4 iptable_filter ip_tables x_tables nf_nat_h323 nf_conntrack_h323 nf_nat_rtsp nf_conntrack_rtsp nf_nat_tftp nf_conntrack_tftp nf_nat_ftp nf_conntrack_ftp nf_nat_irc nf_nat nf_conntrack_irc nf_conntrack nfnetlink aoe sit tunnel4 wlan_wep bridge quota_v2 dm_snapshot dm_mirror dm_mod cpufreq_stats cpufreq_ondemand acpi_cpufreq freq_table tun loop it87 hwmon_vid i2c_isa coretemp 8021q ipv6 snd_hda_intel ftdi_sio wlan_scan_ap snd_pcm snd_timer snd ath_rate_sample usbserial evdev intel_agp soundcore snd_page_alloc i2c_i801 ath_pci wlan usblp i2c_core ath_hal(P) parport_pc parport pcspkr ext3 jbd mbcache raid456 xor raid1 raid0 md_mod ide_generic ide_cd cdrom ata_generic sd_mod usbhid hid jmicron r8169 firewire_ohci fire wire_core crc_itu_t ahci generic ide_core e1000 ehci_hcd libata scsi_mod uhci_hcd thermal processor fan Pid: 11409, comm: qemu-system-x86 Tainted: P 2.6.22-2-amd64 #1 RIP: 0010:[<ffffffff8839a3dd>] [<ffffffff8839a3dd>] :kvm:mmu_memory_cache_alloc+0xd/0x29 RSP: 0018:ffff8102206a39c8 EFLAGS: 00010246 RAX: 0000000000000000 RBX: ffffc20013238810 RCX: 0000000000000028 RDX: ffff810133d84088 RSI: 0000000000000028 RDI: ffff8101c5b04758 RBP: ffff8101c5b04440 R08: 0000000000000000 R09: 0000000000000004 R10: 00000000071c2067 R11: ffffffff885a137c R12: ffff8101009c6010 R13: 0000000000000002 R14: ffff8101c5b04440 R15: ffff8101009c6010 FS: 00002b2e3cc37550(0000) GS:ffff810227b29b40(0000) knlGS:0000000000000000 CS: 0010 DS: 002b ES: 002b CR0: 0000000080050033 CR2: 00000000005b19a4 CR3: 000000014f225000 CR4: 00000000000026e0 Process qemu-system-x86 (pid: 11409, threadinfo ffff8102206a2000, task ffff810226c370a0) Stack: 00000000000071c2 ffffffff8839a48c 000000018c586047 000000018c586000 0000000000000045 ffffffff8839ae92 0000000000000001 00000000000071c2 0000000000000000 0000000000000000 00000000071c2000 00000000071c2000 Call Trace: [<ffffffff8839a48c>] :kvm:rmap_add+0x85/0xe7 [<ffffffff8839ae92>] :kvm:paging64_set_pte_common+0x1c5/0x22e [<ffffffff8839af45>] :kvm:paging64_set_pte+0x4a/0x4f [<ffffffff8839b202>] :kvm:kvm_mmu_pte_write+0x2b8/0x328 [<ffffffff88396581>] :kvm:emulator_write_emulated_onepage+0x6e/0xce [<ffffffff8839f697>] :kvm:x86_emulate_insn+0x2ba1/0x4146 [<ffffffff8839c85d>] :kvm:x86_decode_insn+0x78c/0xa25 [<ffffffff885a1377>] :kvm_intel:vmcs_readl+0x17/0x1c [<ffffffff88396a57>] :kvm:emulate_instruction+0x152/0x290 [<ffffffff885a3a57>] :kvm_intel:handle_exception+0x170/0x250 [<ffffffff88397492>] :kvm:kvm_vcpu_ioctl+0x357/0xf57 [<ffffffff80229db3>] task_rq_lock+0x3d/0x6f [<ffffffff80229976>] __activate_task+0x26/0x38 [<ffffffff8038b360>] memcpy_toiovec+0x36/0x66 [<ffffffff8038b7aa>] skb_copy_datagram_iovec+0x49/0x1ed [<ffffffff80243de3>] remove_wait_queue+0x12/0x45 [<ffffffff883b998f>] :tun:tun_chr_aio_read+0x2a8/0x2ba [<ffffffff8028fe5c>] core_sys_select+0x234/0x265 [<ffffffff8023aec4>] __dequeue_signal+0x19/0x15a [<ffffffff8023c4bc>] dequeue_signal+0xa5/0x126 [<ffffffff8024722b>] getnstimeofday+0x32/0x8b [<ffffffff8028eb9f>] do_ioctl+0x2b/0xb6 [<ffffffff8028ee77>] vfs_ioctl+0x24d/0x266 [<ffffffff8028eee9>] sys_ioctl+0x59/0x7c [<ffffffff80209d8e>] system_call+0x7e/0x83 Code: 0f 0b eb fe ff c8 89 07 48 98 48 8b 54 c7 08 31 c0 fc 48 89 RIP [<ffffffff8839a3dd>] :kvm:mmu_memory_cache_alloc+0xd/0x29 RSP <ffff8102206a39c8> -- .''`.
