Today I have a new problem, I'm using VirtualBox version 6.0, the virtual machine is running Ubuntu 14.04.6 LTS
I'm using Qt Creator in the VM and after a while and with nothing displayed the VM stops responding, the only thing I can do is close the VM and relaunch, loosing anything I haven't saved.

Re: VM keeps crashing
We need to see a complete VBox.log, from a complete VM run, where the problem occurs:
- Start the VM from cold-boot (not from a paused or saved state) / Observe problem / Shutdown the VM (force close it if you have to).
- With the VM completely shut down (not paused or saved), 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.
Do NOT send me Personal Messages (PMs) for troubleshooting, they are simply deleted.

If you obfuscate any information requested, I will obfuscate my response. These are virtual UUIDs, not real ones.

Re: VM keeps crashing
Your system only has 4 physical CPU cores.
Please try setting the guest to 2 or 3 vCPU, so that the host still has a free core to handle the VM?

Re: VM keeps crashing
Just like Martin said, lower the vCPU allocation for your guest. I have mine set to 2 usually out of the 4 cores of my host.00:00:01.185427 NumCPUs <integer> = 0x0000000000000004 (4) 00:00:01.329234 CPUM: Physical host cores: 4
Go to the VM Settings » Storage » select the SATA controller » Use Host I/O Cache: enable that.00:00:01.185499 [/Devices/ahci/0/LUN#0/Config/] (level 5) 00:00:01.185501 BlockCache <integer> = 0x0000000000000001 (1)

- Why Qt Creator in a VM when there's a native OSX implementation?
- Which Qt version? Maybe I could try and replicate it...

Re: VM keeps crashing
Thank you for your post, I have reduce CPU's to 2 and enabled Host I/O Cache. I'm using Ubuntu because the SDK I have to use for the target hardware is only available as an old version that is only compatible with Linux Ubuntu.
