Virtualbox 6.1.0, "signal 6" when starting a VM

Post by weekiat »


ModEdit; split post from Virtualbox 6.1.0 not working
i have the same problem too...

i am using Ubuntu 18.04, almost newly installed OS, and installed Virtualbox 6.1.

even when I try to create brand new VM with no OS yet cannot start, and give me the error:

Code: Select all

The virtual machine 'Ubuntu 18.04' has terminated unexpectedly during startup because of signal 6.

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: MachineWrap
Interface: IMachine {85632c68-b5bb-4316-a900-5eb28d3413df}

No, actually you don't. Not the same conditions, not the same error code. Not sure where exactly you see the similarities...

In order to better understand the problem you need to submit some more information. Please read the following: Minimum information needed for assistance.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.

i see..

Version of VirtualBox: 6.1.0 r135406 (Qt5.11.2)
Guest Additions: None (Have tried installing it, same issue)

My Host OS version
$ uname -a
Linux roadsweeperavms-ThinkStation-P920 5.0.0-37-generic #40~18.04.1-Ubuntu SMP Thu Nov 14 12:06:39 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
Free memory on Host OS:
$ free -m
              total        used        free      shared  buff/cache   available
Mem:          15632        1859       12536         113        1236       13341
Swap:          2047           0        2047
Guest VM OS info is irrelevant, since I have not installed the OS and it already cannot even start.

log files as attached.

A guest VM log (vbox.log in the guest's Logs folder) tels a lot more than just what OS is in it. Lots of troubleshooting info available even if no OS is installed yet. Best zip and post that log....

Googling:

"signal 6" site:virtualbox.org

Shows some oposts saying there's a glitch drawing the guest, and a host restart might help. Seems to happen on Mac & Linux hosts.

Actually, it is. From the "VBoxSVC.log":
Launched VM: 7808 pid: 3471 (0xd8f) frontend: GUI/Qt name: Ubuntu 18.04 (OAuth2)
So, as 'scottgus1' said, find, ZIP and attach "/home/roadsweeperavms/VirtualBox VMs/Ubuntu 18.04 (OAuth2)/Logs/VBox.log" from a failed session...

oh yes that instance is exported from another virtualbox (as OVA format) that i am using on another machine (which has absolutely no problems running this instance). I had thought my exported VM has issues, so I tried creating a brand new VM on this machine and it couldn't even start up in order to install any OS, but at least i know it isn't due to the exported image has issues.

sorry, maybe another silly question, i cannot find any logs available for the VM instance. there is no Logs folder. even when I manually create the logs folder, no logs are created when i start the VM instance. hence all the logs i have are in the ~/.config/VirtualBox folder.
~/VirtualBox VMs/Ubuntu 18.04 (OAuth2)$ ls -l
total 13044068
drwxr-xr-x 2 roadsweeperavms roadsweeperavms        4096 Dec 16 11:17  Logs

p.s. the Logs folder above is manually created.

update:
seems that the VM runs if i start in headless mode, but because it is headless mode there is no GUI, and i need to access the GUI

and the logs file appeared after i started the VM in headless mode, attached are the logs of the VM running in headless mode

Here's one thing I see:
00:00:00.171911 [/Devices/vga/0/Config/] (level 4)
00:00:00.171915   3DEnabled          <integer> = 0x0000000000000001 (1)
....
00:00:00.171975   VMSVGA3dEnabled    <integer> = 0x0000000000000001 (1)
00:00:00.171979   VMSVGAEnabled      <integer> = 0x0000000000000001 (1)
00:00:00.171981   VMSVGAPciBarLayout <integer> = 0x0000000000000001 (1)
00:00:00.171983   VMSVGAPciId        <integer> = 0x0000000000000001 (1)
00:00:00.171986   VRamSize           <integer> = 0x0000000004000000 (67 108 864, 64 MB)
Correct VMSVGA video card for Linux guests, but probably way too little video memory for 3D acceleration. Max that slider out, 256MB.

There's something unusual about the Guest Additions:
00:00:15.607500 VMMDev: Guest Additions information report: Version 6.0.6 r129722 '6.0.6_KernelUbuntu'
00:00:24.087251 VMMDev: Guest Log: 00:00:00.000793 main     Executable: /opt/VBoxGuestAdditions-5.2.18/sbin/VBoxService
Uninstall whatever Guest Additions are in the guest then install the Guest Additions from the built-in ISO that came with your 6.1.0 Virtualbox (guest Devices menu, Insert Guest Additions CD image, look in guest's CD drive). Matching Guest Additions is probably necessary when running with 3D acceleration.

Sweet PC! Please pack up and send it to me so I can test this issue further. :lol:

Actually there is a GUI, only the window that shows it isn't open. You can remote into the guest's Virtualbox RDP server if the server and port are enabled and set, and you can see the guest GUI.

Headless guests do not have 3D acceleration, which may be the cause of why the guest won't boot normally. "Signal 6" googled out as being guest-GUI-influenced, too.
