Windows Server 2019 running very slow (unusable)

[KiwiiwiK]

I'm running a Windows Server 2019 VM with 6GB of Ram and 4 virtual cores, but the screen keep freezing everytime

It's impossible to do anything on that machine!

I already tried to change the disk format but didn't help neither

Please right-click the guest in the main Virtualbox window's guest list, choose Show Log.

Search the far left tab's log for this text:

Attempting fall back to NEM

If you find it, Hyper-V is enabled. See HMR3Init: Attempting fall back to NEM (Hyper-V is active).

If you don't find that text, save the far left tab's log, zip the log file, and post the zip file, using the forum's Upload Attachment tab.

It worked!

Thank you

Great! Glad you're up and running.
