Call to NEMR0InitVMPart2 failed: VERR_NEM_INIT_FAILED

Post by JWSchuetz »

Mod Edit: In attempting to prepare for Windows 11 Hyper-v/Virtualbox coexistence, 6.1.28 introduced a bug that broke Windows 10 Hyper-v/Virtualbox coexistence.

Revert to your previous version if you must have Hyper-V enabled, or disable Hyper-V: VERR_NEM_VM_CREATE_FAILED: What do I do?


Hi,

I was using version 6.1.26 with no problems and I just installed the new version 6.1.28 on my WIN10 host.

Trying to start a debian 11 guest i got the following error: Call to NEMR0InitVMPart2 failed: VERR_NEM_INIT_FAILED

Please provide logs as zipped attachments, don't just spray text all over us.

See viewtopic.php?f=6&t=104175 as it's been introduced in 6.1.28.

Go back to 6.1.26 or 6.1.27 and the error will not occur.

As for spraying, if QAT testing was done then this issue would not have occurred. It is a simple regression that should have been picked up in the QAT testing. See my post in viewtopic.php?f=6&t=104175 for the testing I did that shows is which versions the problem does NOT apprear in.

You think the devs don't test?

Bugs get through sometimes. And host OS's change unexpectedly too. And user pebcak errors occur.

And how a log is posted has nothing to do with testing.

Stay focused on the problem at hand. "One issue per thread"

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

Please right-click the VM in the main Virtualbox window's VM list, choose Show Log. Save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

You seem to be under the impression that you're a client. Not so. You are a QA tester. People like you and me are what ensures that paying customers get a quality product.

Thanks alltogether for your help.

After disabling hyper-v in my Windows 10 host, VirtualBox works now fine for me. And the new Linux kernel-release is now supported! :D :D :D

As the other thread (viewtopic.php?f=6&t=104175) has been locked I am updating this thread with the additional testing I have done as included blow. I have also updated ticket 20624 to include this inf for the devs when they get the ticket assigned to them or when the eventually look at it.

There are new test builds available, but they are also failing as per the following versions:
VB 6.1.29r147791 has the issue.
VB 6.1.97r147788 has the issue. VB 6.1.97r147373 does not exhibit the issue.

So now all of the stable and test builds are failing, so make sure you keep copies of the version of VirtualBox that works for you before updating or testing later versions.

Thanks for the update.

FWIW, the previous release update versions (e.g. VirtualBox 6.1.26) are still available as usual on Download VirtualBox (Old Builds): VirtualBox 6.1.

In fact I did. But other people reading only your last but one post in this thread could get the impression that they even have to keep copies of previous release versions, which isn't true.

Same here. The latest version 6.1.28 is broken.
Just downloaded 6.1.26 and installed it back from Downloads -> VirtualBox older builds -> VirtualBox 6.1.
Unfortunatelly it seems that devs won't fix that which is shame (it is better for them to argue).

Just created an account to add my bit here as well -
Had this exact issue, tried all fixes that I could read about and all failed - Downloaded and installed 6.1.26 and downgraded the ext pack, all worked fine.
Didn't even need to uninstall - just ran the installers for the old version and worked right out the box.

The devs aren't here arguing, they're busy trying to fix the bug. Do give them a chance! :roll:
