I've recently exported the image and am running it on 4.0.8 and 4.2.4 -- where I now get kernel panics (about once every three days when running under heavy load). There's nothing that appears in the virtual box logs; it's strictly in the /var/log/messages on the guest. While I can't say confidently that the panic is always the same place, my recollection is that it's very similar (backtrace at the bottom). contents of /var/log/messages from latest panic: {{{ Dec 12 08:13:35 jhf-fc7 kernel: BUG: unable to handle kernel paging request at virtual address 69762055 Dec 12 08:13:35 jhf-fc7 kernel: printing eip: Dec 12 08:13:35 jhf-fc7 kernel: c0470184 Dec 12 08:13:36 jhf-fc7 kernel: *pde = 00000000 Dec 12 08:13:36 jhf-fc7 kernel: Oops: 0000 [#1] Dec 12 08:13:36 jhf-fc7 kernel: SMP Dec 12 08:13:36 jhf-fc7 kernel: Modules linked in: vboxsf(U) autofs4 hidp fuse rfcomm l2cap bluetooth sunrpc nf_conntrack_netbios_ns nf_conntrack_ipv4 xt_state nf_conntrack nfnetlink ipt_REJECT iptable_filter ip_tables xt_tcpudp ip6t_REJECT ip6table_filter ip6_tables x_tables ipv6 dm_multipath video output sbs battery snd_intel8x0 snd_ac97_codec ac97_bus snd_seq_dummy snd_seq_oss snd_seq_midi_event snd_seq snd_seq_device snd_pcm_oss snd_mixer_oss parport_pc parport snd_pcm floppy pcspkr i2c_piix4 ac snd_timer snd i2c_core button soundcore snd_page_alloc pcnet32 vboxguest(U) mii sg sr_mod cdrom dm_snapshot dm_zero dm_mirror dm_mod ata_piix ata_generic libata sd_mod scsi_mod ext3 jbd mbcache ehci_hcd ohci_hcd uhci_hcd Dec 12 08:13:36 jhf-fc7 kernel: CPU: 0 Dec 12 08:13:36 jhf-fc7 kernel: EIP: 0060:[] Not tainted VLI Dec 12 08:13:36 jhf-fc7 kernel: EFLAGS: 00210206 (2.6.23.17-88.fc7 #1) Dec 12 08:13:36 jhf-fc7 kernel: EIP is at find_vma+0x2d/0x53 Dec 12 08:13:36 jhf-fc7 kernel: eax: 69762065 ebx: 05106000 ecx: 6976204d edx: e10935d8 Dec 12 08:13:36 jhf-fc7 kernel: esi: f18848c0 edi: dd659ed8 ebp: f18848c0 esp: dd659e84 Dec 12 08:13:36 jhf-fc7 kernel: ds: 007b es: 007b fs: 00d8 gs: 0033 ss: 0068 Dec 12 08:13:36 jhf-fc7 kernel: Process niWrapperServer (pid: 13106, ti=dd659000 task=c976cc20 task.ti=dd659000) Dec 12 08:13:36 jhf-fc7 kernel: Stack: 051067cc 05106000 c0470774 051067cc 05106000 dd659ed8 c0445554 00000000 Dec 12 08:13:36 jhf-fc7 kernel: 49aa7e22 00200246 005e0030 00000000 f18848f8 f18848f8 051067cc dd659ed8 Dec 12 08:13:36 jhf-fc7 kernel: 00000001 f18848f8 c04464b1 00000001 dd659f64 c04f59f8 00000000 000007cc Dec 12 08:13:36 jhf-fc7 kernel: Call Trace: Dec 12 08:13:36 jhf-fc7 kernel: [] find_extend_vma+0x12/0x49 Dec 12 08:13:36 jhf-fc7 kernel: [] get_futex_key+0x6e/0x122 Dec 12 08:13:36 jhf-fc7 kernel: [] futex_wake+0x28/0xb0 Dec 12 08:13:36 jhf-fc7 kernel: [] copy_to_user+0x34/0x48 Dec 12 08:13:36 jhf-fc7 kernel: [] do_futex+0x7f/0x959 Dec 12 08:13:36 jhf-fc7 kernel: [] sys_futex+0xfd/0x110 Dec 12 08:13:36 jhf-fc7 kernel: [] do_syscall_trace+0xd7/0xde Dec 12 08:13:36 jhf-fc7 kernel: [] syscall_call+0x7/0xb Dec 12 08:13:36 jhf-fc7 kernel: ======================= Dec 12 08:13:36 jhf-fc7 kernel: Code: c6 31 c0 85 f6 53 89 d3 74 44 eb 04 89 ca eb 39 8b 46 08 85 c0 74 0a 39 50 08 76 05 39 50 04 76 2d 8b 46 04 31 d2 eb 17 8d 48 e8 <39> 59 08 76 0c 39 59 04 76 d7 8b 40 08 89 ca eb 03 8b 40 04 85 Dec 12 08:13:36 jhf-fc7 kernel: EIP: [] find_vma+0x2d/0x53 SS:ESP 0068:dd659e84 }}}" defect closed other VirtualBox 4.2.4 fixed Linux Linux
