Kernel: 5.15.58-1.mga8 x86_64
10-Core Intel Core i9-7900X
NVIDIA GeForce GTX 1080 Ti

All three flavours of the  the new kernel installed without incident.

After reboot most things seemed to be working including bluetooth audio but virtualbox would not run.  Crashed immediately.  NS_ERROR_FAILURE
virtualbox-6.1.36-1.mga8

Tried:
$ sudo urpme dkms-virtualbox
That took a very long time.
# urpmi dkms-virtualbox
Package dkms-virtualbox-6.1.36-1.mga8.x86_64 is already installed

It was working a month ago.

@Len: Do VB launch for you on our 5.15.55 kernel?

VirtualBox works OK for me on the new backport kernel Bug 30689.

Len, did you remember to update the extension pack?

@Morgan: shall check that after some sleep.  Thanks.

@Dave: No.  Did not even realise that it was necessary.  Still an absolute beginner with virtualbox.  Don't actually use it for anything except testing kernels.  Thanks.

You need the new extension pack :)

It looks like the latest extension pack was already in place.  And, as said, it was working a month ago with an earlier kernel.

Looks like data center problems are fixed

Having ruled out in private messages a version problem for the extension packs,
etc., I checked the VBox.log from my working VirtualBox install.

And lots more messages as I ran/then stopped the guest.

Two more things to check. Is the file system full (df -h)? Any chance the
cmos settings were lost and it reverted to having virtualization disabled?

Well, technically you dont need the extension pack unless you want to use theese features for the client vms:

Oracle Cloud Infrastructure integration, USB 2.0 and USB 3.0 Host Controller, Host Webcam, VirtualBox RDP, PXE ROM, Disk Encryption, NVMe.


but _if_ it's installed, it must match the version on the host, so currently it must show version 6.1.36r152435 in VritualBox Preferences.

A month ago we didn't have 6.1.36, as I built that one on 2022-07-21, and released it as an update on 2022-07-25



one thing to test is to remove the extension pack, check that the client vm works without it, then try to re-install the extension pack and see if it breaks down again...

@tmb in reply to comment 9:
No, virtualbox guests now launch OK - managed to sort out the numbers.  I also ran vbox with the desktop kernel and that also worked.  Had not been able to post a report.  The main trouble now is that vbox with either kernel fails to connect to external USB devices even though they are registered in settings.  USB has worked on past systems so there must be something I have missed.

An update for this issue has been pushed to the Mageia Updates repository.
