Description

From the backtrace, it looks like a KVM module but, not a kernel bug. Oh, it's 5.4.z, so it's because the patches from bug #510814 aren't included on the kernel package. Moving back to the kernel component, and adding bug #510814 as dependency. (In reply to comment #0) > Additional info: > a. host work well when offline/online cpu without running guest. > b. host work well on 2.6.18-182.el5 with kvm-83-140 So is it only a 5.4.z issue? It does not worth fixing. > c. offline cpu->online cpu then start guest, also lead to host kernel panic > > > 1. host kernel > 2.6.18-164.9.1.el5 > > 2. kvm > kvm-tools-83-105.el5_4.18 > kvm-83-105.el5_4.18 > etherboot-zroms-kvm-5.4.4-13.el5 > etherboot-roms-kvm-5.4.4-13.el5 > kvm-debuginfo-83-105.el5_4.18 > kvm-qemu-img-83-105.el5_4.18 > kmod-kvm-83-105.el5_4.18 > > 3. host cpu > processor : 3 > vendor_id : AuthenticAMD > cpu family : 16 > model : 2 > model name : AMD Phenom(tm) 9600B Quad-Core Processor > > 4. > > Breaking affinity for irq 209 > Breaking affinity for irq 225 > CPU 3 is now offline > Initializing CPU#3 > using mwait in idle threads. > AMD Phenom(tm) 9600B Quad-Core Processor stepping 03 > ----------- [cut here ] --------- [please bite here ] --------- > Kernel BUG at ...-83-maint-snapshot-20090205/kernel-/x86/kvm_main.c:2451 > invalid opcode: 0000 [1] SMP > last sysfs file: /class/cpuid/cpu3/dev > CPU 3 > Modules linked in: tun radeon drm ipt_MASQUERADE iptable_nat ip_nat xt_state > ip_conntrack nfnetlink ipt_REJECT xt_tcpudp iptable_filter ip_tables x_tables > nfsd exportfs nfs_acl auth_rpcgss autofs4 hidp rfcomm l2cap bluetooth lockd > sunrpc bridge ib_iser rdma_cm ib_cm iw_cm ib_sa ib_mad ib_core ib_addr > iscsi_tcp bnx2i cnic ipv6 xfrm_nalgo crypto_api uio cxgb3i cxgb3 8021q > libiscsi_tcp libiscsi2 scsi_transport_iscsi2 scsi_transport_iscsi > cpufreq_ondemand powernow_k8 freq_table dm_round_robin dm_multipath scsi_dh > video hwmon backlight sbs i2c_ec button battery asus_acpi acpi_memhotplug ac > parport_pc lp parport floppy ksm(U) kvm_amd(U) kvm(U) snd_hda_intel > snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss > sr_mod snd_mixer_oss snd_pcm cdrom snd_timer shpchp snd_page_alloc snd_hwdep > i2c_piix4 snd tpm_infineon i2c_core tpm tg3 tpm_bios soundcore serio_raw pcspkr > sg dm_raid45 dm_message dm_region_hash dm_mem_cache dm_snapshot dm_zero > dm_mirror dm_log dm_mod ahci libata sd_mod scsi_mod ext3 jbd uhci_hcd ohci_hcd > ehci_hcd > Pid: 4110, comm: qemu-kvm Tainted: G 2.6.18-164.9.1.el5 #1 > RIP: 0010:[<ffffffff883b1489>] [<ffffffff883b1489>] > :kvm:kvm_handle_fault_on_reboot+0xb/0x16 > RSP: 0018:ffff8101fb951da0 EFLAGS: 00010046 > RAX: ffff8101f2167000 RBX: ffff8101f77b63c0 RCX: 00000000c0000101 > RDX: ffff8101f2167000 RSI: ffff8101f215e000 RDI: ffff8101f237c040 > RBP: ffff8101f237c040 R08: 00000000000000ef R09: 0000000000000000 > R10: ffff81020cdc58a8 R11: ffffffff8003c4dd R12: ffff8101f215e000 > R13: 0000000000000000 R14: 000000000000000f R15: 0000000000001000 > FS: 0000000040b8f940(0063) GS:ffff81021fc1c640(0000) knlGS:0000000000000000 > CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 > CR2: 00002aabbd437000 CR3: 00000001fbd77000 CR4: 00000000000006a0 > Process qemu-kvm (pid: 4110, threadinfo ffff8101fb950000, task > ffff8101f69537e0) > Stack: ffffffff883eaa66 0000000000630096 ffff8101f77b63c0 ffff8101f237c040 > ffff8101f215e000 0000000000000000 000000000000000f 0000000000001000 > ffffffff883b872e fffffffe7ffbfeff ffff8101f1cacb70 ffff81021f02f910 > Call Trace: > [<ffffffff883eaa66>] :kvm_amd:svm_vcpu_run+0x1b0/0x3a5 > [<ffffffff883b872e>] :kvm:kvm_arch_vcpu_ioctl_run+0x397/0x60b > [<ffffffff883b4108>] :kvm:kvm_vcpu_ioctl+0xf2/0x45d > [<ffffffff8008c584>] default_wake_function+0x0/0xe > [<ffffffff80042143>] do_ioctl+0x21/0x6b > [<ffffffff800302cf>] vfs_ioctl+0x457/0x4b9 > [<ffffffff8004c804>] sys_ioctl+0x59/0x78 > [<ffffffff8005d28d>] tracesys+0xd5/0xe0 > > > Code: 0f 0b 68 82 b8 3c 88 c2 93 09 c3 55 48 89 fd 53 31 db 48 83 > RIP [<ffffffff883b1489>] :kvm:kvm_handle_fault_on_reboot+0xb/0x16 > RSP <ffff8101fb951da0> > <0>Kernel panic - not syncing: Fatal exception |
