I recently got a new Laptop (Lenovo Thinkpad L15 G4). And upgraded some hardware:
- RAM: 64 GB DDR4 3200 MHz
- CPU: i5 1335 (10 Cores)
- HostOS: Ubuntu 24.04
I am trying to run Kali Linux in VirtualBox, and when Idle, it sits at 20-30. The minute i just move my mouse, a terminal accross the screen or open Firefox...The CPU goes to 100%. Also, this is not just Kali, I also tested a Windows 11 Guest (same issue).
I tried a bunch of different Resource Konfigurations:
- 16 GB RAM + 8 Cores
- 8 GB RAM + 6 Cores
- 8 GB RAM + 4 Cores
- 8 GB RAM + 2 Cores
- 4 GB RAM + 2 Cores
Between all of them, I had barely any improvement. Also, the VM has 128 MB Video Memory (even tried 256MB when 3D Acceleration is on).
Checked BIOS and the hardware virtualisation VT is switched on. I also tested virt-manager with Kali as a KVM. Same issue.
The Guest (Kali) had the newest Guest Addition (7.2.2), and my VirtualBox is also ( 7.2.2 r170484).
Does anyone have a solution to this issue? Or at least how to get further helpful information. I already checked VBox.log, but there weren't any errors
EDIT:
I uploaded the VBox Log on Pastebin: https://pastebin.com/peE0377c
