#18570 fixed Powering off Guest without Graphics Controller causes Unresponsive Behavior -> fixed in 6.0.8 and 5.2.30 TurtAlgo
Description

I have set the following options on Virtual Machine(s):


Graphics Controller: None
Graphics Memory: 0 MB


Powering off a machine will cause VirtualBox 6.0.6 to behave erratically and unresponsively. Configuring the guest with 5MB Video Memory and a Graphics Controller will allow proper function.

VirtualBox starts the guest again, and reports a memory error, where I have to end the process to fix this issue. I attempted to power off a couple dozen Headless Virtual Machines at once and my Host hung from attempting to restart the Virtual Machines. They also opened up the interface.

I am also having an issue where clicking "Show" on a guest without a Graphics Controller causes issues.


Downgraded to VirtualBox 6.0.4 to fix this issue on a production server. Multiple Virtual Machines power off as expected.

Perhaps configuring a guest with "invalid settings" may be the issue, but I have had no issues with running a guest without a graphics controller. I am running a full box with 200+ machines where I believe there may be unnecessary overhead with a Graphics Adapter.

#18569 fixed Operation Not Permitted Copying Files from Linux Guest to Windows Host via Shared Folder => Fixed in SVN Frank Batschulat (Oracle) William Ruppel

I've changed nothing in the machine settings, and this worked fine in 6.0.4. Also, I see there were changes in 6.0.6 related to shared folders.

So, I think something has regressed.

Thanks.
