WIndows server 2019 core Guest Additions not working

Post by Doobis »

I have updated my virtual box env, installed and reinstalled the guest additions but I cant get it to work. Copy and paste wont work and It wont accept any screen resolution changes. OS is windows server core 2019. I just updated to virtual box 7.0.6. Not sure what I am doing wrong.

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

Right-click the VM in the main Virtualbox window's VM list, choose Show in Explorer/Finder/File Manager. In the "Logs" subfolder, zip the VM's "vbox.log", and post the zip file, using the forum's Upload Attachment tab. (Configure your host OS to show all extensions so you can find the "vbox.log", not "vbox.log.1", etc.)

Virtualbox and Extension Pack versions:
00:00:03.622047 VirtualBox VM 7.0.6 r155176 win.amd64 (Jan 11 2023 16:38:38) release log
00:00:03.696867 Installed Extension Packs:
00:00:03.697219 Oracle VM VirtualBox Extension Pack (Version: 6.1.34 r150636; VRDE Module: VBoxVRDP;
First, the Extension Pack is old. The EP version must match the installed Virtualbox version on the host.

Is this the text-only command prompt version?

7.0.6 Guest Additions are installed and running, according to the log.

Did copy/paste and screen size changes work before?

These are all new installs. It works on a standard gui version of server 2019 but not the core version. Yes core is command line.

I suspect that a GUI is needed for Guest Additions to work.

I would think so too. There are several prompts which need a reply to continue.

How is the OP using copy/paste in a core version anyway? RDP? I guess you could install the GAs using RDP as well.
