VM is always locking up some time after boot.

[realguystuff]

Yesterday, I made a Windows 8.1 VM, and I wanted to use it for testing purposes. However, this afternoon, my VM always lock up sometime after boot. It has Guest Additions. I tried going to the development builds to see if it got fixed, but unfortunately, it still happens.

Please provide a VM log file. Make sure the VM is fully shut down, then right click it in the manager UI. Select "Show Log" and save "VBox.log" (no other file) to a zip file. Attach the zip here.

There are two files, VBox.log and VBoxHardening.log. I will provide them both in case you need it.

FYI, I turned off 3D acceleration and I placed it to 1 core only. However, it is still happening.

I see you are using a test build of VirtualBox, can you tell me why? Regardless of the answer, you have a mismatched extension pack installed, which is not allowed.

Next problem, you don't have enough RAM to do a good job of running Win11 and Win8.1 at the same time on this PC. In particular you can't afford 2GB RAM for this VM unless you can find a way to free up host RAM. I would not try to run Win8.1 with less.

00:00:05.646839 Host RAM: 7991MB (7.8GB) total, 2138MB (2.0GB) available
...
00:00:05.851865 RamSize <integer> = 0x0000000080000000 (2 147 483 648, 2 048 MB)
00:00:05.852113 VRamSize <integer> = 0x0000000008000000 (134 217 728, 128 MB)

You should set the VM to 2 cores, as modern Windows will usually lag badly with only one.

And worst of all, you have Hyper-v enabled.

00:00:05.934631 NEM: NEMR3Init: Snail execution mode is active!
00:00:05.934631 NEM: Note! VirtualBox is not able to run at its full potential in this execution mode.
00:00:05.934631 NEM: To see VirtualBox run at max speed you need to disable all Windows features
00:00:05.934631 NEM: making use of Hyper-V. That is a moving target, so google how and carefully
00:00:05.934631 NEM: consider the consequences of disabling these features.
00:00:05.934631 NEM:

HMR3Init: Attempting fall back to NEM (Hyper-V is active)

I am on Windows Home Single, so I don't have Hyper-v enabled, or any else. I have WSL on, so I turned it off (aw man)

[AndyCot]

If you have WSL then under the hood Hyper-V is enabled.

WSL uses Hyper-V to work.

Disabling WSL will NOT disable Hyper-V!!!!

[realguystuff]

How do I turn off Hyper-V then?

Read mpack's post above.

I followed everything, and it seemed to make things worse. Now, the VM that used to be 2GB, is now on >2GB but <4GB, but now it's a little slow. Anyone explain?

you don't have enough RAM to do a good job of running Win11 and Win8.1 at the same time on this PC.

Messing around with the exact numbers doesn't really change this.

If you believe that you followed the steps in the FAQ then please provide a new (zipped) VBox.log file.
