Windows Guest Crashes on load @ login screen
Hi Y'all,
I recently updated my windows 10 x64 Pro OS (Host) to the latest version and Virtualbox from v6 to v7. Now when I load any vMachine created with previous versions (5 & 6) everthing crashes at load - or shortly thereafter. Sometimes I can login to the vMachine, often *not*!
Is anybody able to help me with this please?
I enclose the logfile & VBoxHardening logs(zipped). The PNGs in the 'Logs' Dir are not helpful and contain to indications of the causes
(edited for more precision and stupid typos!)

Re: Windows Guest Crashes on load @ login screen
@David. I don't know if this is your problem, but you have an extension pack mismatch. These need to be the same version.
You should also increase the graphics RAM. The current 60MB may not be enough since you enabled a 4K display size. And btw I doubt you can run a display that size without enabling 3D acceleration.00:00:12.645904 VirtualBox VM 7.0.10 r158379 win.amd64 (Jul 12 2023 18:34:34) release log

Re: Windows Guest Crashes on load @ login screen
@mpack,
thanks for the heads-up, I used to be moderately proficient in running VirtualBox and could nearly always figure out a resolution to diverse issues. I think that the confusion about the extensions, this used to be more straightforward IMHO, but rel 7 did get me a bit flustered in this respect. The graphics RAM has not been changed since rel. 5 and simply put I did not even think of that ... even after adding the new bigger display!.
I will get on the extensions issue and report back!

@mpack:
Sadly the situation has not improved, I 'think' that the extensions have been installed correctly. I have attached the last log file, should you care to check. Thanks

Re: Windows Guest Crashes on load @ login screen
I also do not see anything egregiously wrong with the VM. Hyper-V is enabled on the host OS, which may or may not be causing the problem. HMR3Init: Attempting fall back to NEM (Hyper-V is active) Hyper-V may have been enabled by the host OS update.
Does this mean that VM's created fresh under 7.0 run OK?DavidElDee wrote: ↑29. Aug 2023, 09:24 when I load any vMachine created with previous versions (5 & 6) everthing crashes at load - or shortly thereafter.

Re: Windows Guest Crashes on load @ login screen
The key information of the crash log is a "NEM unrecoverable exception", which can only happen when running in NEM (Native Execution Mode aka Hyper-V), so eliminating Hyper-V will serve as a workaround.

@ scottgus1
To your query:
"Does this mean that VM's created fresh under 7.0 run OK?"
... the answer is "No", I haven't got around to trying that yet ...

I checked on the state of this Windows feature, according to Windows, Hyper-V is 'OFF' (Attachment)scottgus1 wrote: ↑29. Aug 2023, 18:53 I also do not see anything egregiously wrong with the VM.

Re: Windows Guest Crashes on load @ login screen
I checked in the linked tutorial and it says to not bother looking at Windows Features to see if Hyper-V is enabled.
Tutorial links are posted to be read carefully.

Re: Windows Guest Crashes on load @ login screen
I have disabled Hyper-V according to the tutorials and the VM now seems to run stably. Thanks for the help, and sorry for my (initial) inability to read the instructions
