Sonoma on i7 - VM & host run extremely slow

Post by rocioa20 »

H E L P!

I'm taking a cybersec course for which I had to install virtual box and then Kali Linux. The thing is that it makes both the host and the kali go extremely slow GREEN TURTLE SLOW.
I know a possible solution is to downgrade to Monterey (but I don't want to : :( ) is there a way to get rid of the "green turtle"? please help!!

On macOS (and VirtualBox 7.0) there is no way to get rid of the green turtle. That said, on this platform it isn't known to be super slow. You need to provide details about your VM, the detailed config and so on...

Thank you so much for replying, I had missed your reply.

My host is a MacBook Air 2020
1,2 GHz Intel Core i7 - 4 cores
Mac Sonoma 14.5

The VBox version I'm using is the 7.0, macOS wouldn't let me virtualize any machine with a previous version.
in this virtual box I have a kali linux, Ubuntu 64 bits with:
- 4 GB Ram
- 4 Processers

Not sure which other info might be helpful? Thanks!

A 'zipped' copy of the VM VBox.log file should help the analysis. You can upload the file using the Attachments Tab at th bottom of the message screen.

But one hint: If your MacBook Air has 4 physical cores it's not going to help the performance of either the Host Mac or the Guest VM's performance if you allocate all 4 CPU Cores to the Guest! Divide the available 'real' physical CPU cores equally between Host and Guest. 2 Cores is normally the 'sweet spot' for 64-bit Guests; and it also matches the minimum spec quoted for a 'Debian-based' 64-bit OS installation on a physical PC.
