Public bug reported: Hello
When starting any VM, Locked on ‘Starting virtual machine’ I get two! (not one) Start VM dialogs On one, progress to 0 Other (labelled Starting virtual machine 2/2) Progress goes to 20% but both freeze. Virtual Box Manager also freezes, so I either need to log out, or kill the virtualbox process from a terminal. Oracle VirtualBox team would not support as its OSE (so not their build), but they did say following vbog logs pointed to the problem 00:00:00.899466 Package type: LINUX_64BITS_GENERIC (OSE) 00:00:00.925013 Installed Extension Packs: 00:00:00.925044 VNC (Version: 5.0.40 r115130; VRDE Module: VBoxVNC) 00:00:00.925052 Oracle VM VirtualBox Extension Pack (Version: 4.1.34 r95024; VRDE Module: VBoxVRDP unusable because of 'Incompatible extension pack (version '4.1.34'), please update') Also following unix command output dmesg |grep vbox [ 51.244798] vboxdrv: module verification failed: signature and/or required key missing - tainting kernel [ 51.253612] vboxdrv: Found 4 processor cores [ 51.273172] vboxdrv: TSC mode is Invariant, tentative frequency 2527318349 Hz [ 51.273179] vboxdrv: Successfully loaded version 5.0.40_Ubuntu (interface 0x00240000) [ 51.492642] vboxpci: IOMMU not found (not registered) [ 1600.960789] Modules linked in: bnep pci_stub vboxpci(OE) vboxnetadp(OE) vboxnetflt(OE) vboxdrv(OE) drbg ansi_cprng ctr ccm bluetooth xen_gntdev xen_evtchn xenfs xen_privcmd binfmt_misc uvcvideo videobuf2_vmalloc videobuf2_memops videobuf2_v4l2 videobuf2_core v4l2_common videodev media arc4 ath9k ath9k_common hp_wmi snd_hda_codec_hdmi ath9k_hw sparse_keymap snd_hda_codec_idt ath snd_hda_codec_generic mac80211 snd_hda_intel snd_hda_codec snd_hda_core snd_hwdep cfg80211 snd_pcm snd_seq_midi snd_seq_midi_event snd_rawmidi intel_powerclamp snd_seq joydev snd_seq_device input_leds coretemp snd_timer serio_raw snd hp_accel soundcore mei_me lis3lv02d shpchp mei lpc_ich input_polldev mac_hid cuse parport_pc ppdev lp parport autofs4 dm_mirror dm_region_hash dm_log dm_snapshot dm_bufio hid_generic usbhid hid [ 1600.962045] [<ffffffffc07543f7>] ? supdrvIOCtl+0x2de7/0x3250 [vboxdrv] [ 1600.962083] [<ffffffffc074d5b0>] ?
