VMs crash due to segmentation fault: 11

Postby martyn314 » 21. Oct 2021, 16:37

I'm attempting to install Ubuntu on Big Sur 11.6 using VirtualBox 6.1.28 and am getting an error where the VM crashes with a segmentation fault after several minutes. The full error message is in the attached doc. It seems to mostly happen when I use the mouse on an app outside of VirtualBox. I've seen similar reports related to installing, but this doesn't seem identical - I managed to get Ubuntu installed and then saw the same fault later on. Any suggestions on what I can do to make it stable?

I've just found ?f=8&t=102320&p=496900&hilit=segmentation#p496900 which seems to have some hints, will check those out.

Please try if entering the following command, while the VM is not running, makes any difference:

Code: Select all   Expand viewCollapse view
VBoxManage setextradata "VM Name" GUI/HidLedsSync 0

See the VirtualBox User Manual: 9.25. Support for Keyboard Indicator Synchronization

Thanks for the tip. I've tried it and the VM seems more stable so far. I'll post again if the problem comes back.
