Continuous blocking of linux virtual machines

[boxino]

For a few days all the virutal machines linux block inexorably after a few minutes of use.
What should I post to better report the problem
I use virtualbox 7.0.6
Thank you.

Pick one VM. Start the VM from full normal shutdown, not save-state. Run until you see the problem happen, then shut down the VM from within the VM's OS if possible. If not possible, close the Virtualbox window for the VM with the Power Off option set.

Right-click the VM in the main Virtualbox window's VM list, choose Show in Explorer/Finder/File Manager. In the "Logs" subfolder, zip the VM's "vbox.log", and post the zip file, using the forum's Upload Attachment tab. (Configure your host OS to show all extensions so you can find the "vbox.log", not "vbox.log.1", etc.)

Attach the logs.

Thanks for the logs. They don't show anything on the Virtualbox side that indicates a problem in the "hardware" of the VM. The OS does in fact not appear to have much activity, though, after about 30 seconds.

What exactly is the "block" you see?

[boxino]

The system crashes inexorably...
Image locked, no interaction is possible only the possibility remains to reset the VM.

If you make a new VM under 7.0.6, does it have the same problem?

If you downgrade Virtualbox & Extension Pack back to the version you were using before, do the VMs start working again?

[boxino]

No, I don't have new cars. I have to create it. I don't remember previous versions of Virtualbox & Extension Pack.
If so, where can I download them from Thanks.
I also tried with a machine without extension pack but it freezes all the same.

I tried to install a new virtual machine and insert the guest additions later. I also changed the drivers from NVidia to Nouveau but nothing the machine with linux inside crashes. All available updates installed.

[boxino]

Hello, I redid the test of a new installation creating, this time, also the disk that houses the operating system. At the moment everything seems to be fine. I write from this machine. In case of further problems I update the tread again.
Thank you

Unfortunately, the blockades have resumed again.
The virtual machine suddenly freezes for no apparent reason.

I don't know if this plays any role here, but there are error messages regarding a USB Ethernet adapter (RealTek RTL 8153 chipset).

[boxino]

I hope that is the problem. I keep you updated.
Thank you

The problem has recurred. In fact, one of the machines suddenly slowed down, the other stopped repeatedly. I deselected the 3d video acceleration and at the moment the machines have resumed working. Tips to restore 3d acceleration for more performance. NVidia 1060 6gb video card driver 525.78.01.
There are other display problems. As soon as possible I will open a special tread.
See you.
