Testing a automated debian installation on OS X Mojave Beta (18A371a)

When I power off or VM shuts down the VirtualBox crashes pretty much every time.

Anybody else seen this?

How exactly are you installing it?
Does it happen with a "normal" installation?
Do you have the script/instructions/commands?

PS. For future reference you should ZIP your logs. It helps save a (virtual) tree or two...

Sorry I was a bit short in my description

Created a Debian VM using VirtualBox UI. Nothing automated here.

The VM is set up to do Network boot and that starts a Debian netbook installation. Since I was perfecting this automation I ran it a lot of times and every time it crashed when the installation was finished and I either powered off or if I did a shutdown from Debian.

I think I see a screen/dialog showing for very short time, not long enough to see anything. Seems that the stack trace also indicates this:
Application Specific Information:
objc_msgSend() selector name: setSubmenu:

The problem still exists when I run the VM and then shuts it down. So it's not related to the netboot/automated installation

Should have shorten the log, sorry.

Missing information:
Virtualbox 5.2.18 (just upgraded from a 5.1 version)
MacBook Pro Retina 2012
16GB RAM

I will try to move the VM to another mac to see if it can be reproduced there.

Start the VM from a cold boot. When you try to shutdown the VM and it aborts, right-click on the VM in the VirtualBox Manager and select "Show Log". Save only the first "VBox.log", ZIP it and attach it to your response (see the "Upload attachment" tab below the reply form).

Also, right-click on the VM, "Show in Finder". ZIP the .vbox file and attach that as well.

As you can see from the stack trace, the is crash very deep in Apple's code. You may be better off reporting this to Apple, especially if it's not reproducible on released OS versions.

@michaln:
The crash is probably based on known bugs in QT 5.6.3 for macOS, which have been solved in multiple bugfixes up to QT 5.12 (the current LTS version). For many details regarding this VirtualBox crash see my posts in viewtopic.php?f=8&t=91817.

Why is VirtualBox 6.0 on macOS hosts still based on the old QT LTS version 5.6.3 and not on the current QT LTS version 5.12 (like VirtualBox on current Linux distributions)? How difficult is it to replace the QT library in VirtualBox for macOS?

I wouldn't be so sure about that, I wouldn't bet on it, no way. I'm running VirtualBox (all sorts of versions) in OSX from 10.9.5 (yes, you read that right) up to 10.14.5 and everything in between (literally), and soon 10.15 when it goes public. I have an ext.HD that does nothing else but to boot my 2nd MBP with various OSX/VirtualBox versions.

In none of them I have a crash when shutdown, neither does the majority of people using VirtualBox on OSX. The few that have reported such an issue, have almost always had a heavily modified system (kexts, permissions, etc).

But in any event, you replied to a post about 10.14 beta, that was a long time ago, and that's why I'm thinking that this thread should be locked. I don't know if you wanted to promote your own thread, but if you do, take a look at my last post in your thread (viewtopic.php?f=8&t=91817#p450449) and provide the information requested. In your thread...

Licensing issues. Don't ask for details please...

VirtualBox is *not* based on Qt 5.12 on Linux distros, where did you get that idea? On my Mint19-64 (fresh/virgin) I get:

Version 6.0.8 r130520 (Qt5.9.5)

...and that's because Mint19 comes with Qt 5.9.5.

Generally speaking, VirtualBox uses the Qt version that the distro comes with. If a distro comes with Qt 5.12, then Qt 5.12 is going to be used. If I use the "Generic" Linux version which comes linked with its own set of libraries, and doesn't use the distro provided ones, then I get:

Version 6.0.97 r131153 (Qt5.6.1)
