Guest Additions slows down VM on windows 11

[Bedna]

I recently got a new computer that made me upgrade to win 11. ryzen 9, 3090, 32gb mem, yada yada yada.
Installed the latest ver of virtualbox but got the "missing phyton" warning, installed python but still got the warning but ignored it, it did the same on my win 10 machine and it still worked perfect anyway.
Created a debian-11.5.0-amd64-netinst VM since that was what I was running on my old win 10 machine but after installation the VM ran super sluggy.
I installed Guest Additions together with the debian (when I created the machine) so it took me a while to figure out that THAT is the culprit.

I have tried changes to almost everything, reinstalled the latest version of Guest additions (but since I don't see it in the windows installed apps I cant uninstall it before but rather just install again).

I searched the interweb and the only thing I could find was a post from 2018 (not allowed to post links since new account so I guess I don't provide the link) that describes the same behavior down to the letter, but that got fixed with an update of virtualbox, does that mean this is a bug?

So I made another install but without running the guest additions and voila, runs fluently, but I cant copy paste, unless I SSH with putty into the machine, but c'mon...

EFI install of the image also doesn't work, it doesn't even detect any disks, but that is less important, the copy/paste is!

What do I do?

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.

Forgot to click the "notify me", hence the delayed reply.

*edit. This is an installation of Debian 11.6 but it acts the exact same way as 11.5. I have both setup right now, if you want me to sent me the log file of the vm without the guest additions installed, give me a shout.

Here is the link to the old thread I was mentioning.

Any progress on this?

As for now, I was forced to uninstall and use another VM software, I cant wait 5s to be able to interact with anything graphical in VirtualBox. With my hardware, this is terrible tbh.

Any progress on this?

7.0.6 has been released, I suggest you give it a try. Remember to update the GAs as well. Plus I would update the graphics RAM to 128MB.

And check inside the guest OS process list for CPU hogs. CPU time is like energy: it gets converted into work, it never just disappears.

[Bedna]

I WAS set to max (128) gpu mem, doesn't it say that in the log??
It's better, now I can at least open menus without having to wait 2-5s before I can click. Now it's just graphical lag, but I can live with that I guess, although I have to point out that this should not happen with my hardware, and doesn't on other VM software.

No.

Please repost a zipped log so we can see what has been changed.

[Bedna]

Here ya go.

You somehow seem to have gone backwards. Your previous log showed 7.0.4 GAs.

00:00:18.856365 VMMDev: Guest Additions information report: Version 6.0.0 r127566 '6.0.0'
00:00:18.856383 VMMDev: Guest Additions information report: Interface = 0x00010004 osType = 0x00053100 (Linux >= 2.6, 64-bit)

Yeah, you tell me what happens with the software. I installed the latest ver of VirtualBox (I apparently didn't uninstall the old version so it updated the software).
Started Virtualbox. Got prompted that the guest additions needed to be updated so I agreed and accepted the changes. Started the guest machine and used device>upgrade guest additions.
Updated the actual guest machine software. Rebooted, tested and shutdown. Then gave you the logs.

[scottgus1]

It could be possible the auto update of Guest Additions failed.

Linux distros 'helpfully' pre-install their fork of Guest Additions in their OS's on the off chance it will be installed in a Virtualbox VM. Doesn't help much with Official Virtualbox.

Or it's a mix of fork & official GAs, which is worse.

Please try manually uninstalling and purging everything related to the Guest Additions inside the VM OS. Reboot, then handle the prerequisites and install 7.0.6 GAs manually: https://www.virtualbox.org/manual/ch04. ... ions-linux and https://www.virtualbox.org/manual/ch02. ... nux-prereq. Also, watch the terminal installation report when running the GAs installer. Error messages will show if the install ran into a problem.

Then please re-post a zipped log.

IDK whats going on, clearly 7.0.6 was installed, and uninstalled 2 times then reinstalled during this process and we are back to the terrible way it was before it "kinda" worked for me. The whole Guest freezes every few seconds, can't even type freely in a terminal, ie, input is not being buffered. sigh
