Virtualbox 7 on MacOS Monterey - Windows 7 guest vm super slow

[christiancwc]

After upgrade Virtualbox on MacOS Monterey to version 7.0.10, my Windows 7 guest vm runs super slow.
I have tried many solutions and without success.
Can anyone help please?

The log file has attached.

Have you run any other 7.0 versions on this Mac?

BTW, zipped logs almost always fit, which makes splitting the logs unnecessary.

No other Win 7 run on this Mac recently, the guest Win 7 I used for few years without any problem.
Thank you for your reply!

I'm sorry, I meant, have you run any other Virtualbox 7.0 versions besides 7.0.10?

VirtualBox 7.x uses Apples built-in hypervisor. Since you are on Monterey, you may be better off running VirtualBox 6.1.46 which will give better performance.

Monterey still allows kernel extensions (kexts) to be installed, although with a warning that they are deprecated. Also, support for VirtualBox 6.1.x ceases at the end of this year so that may be another factor to consider.

ok, it seems like the problem of hypervisor on MacOS, I found the green turtle was on even tried to create a new guest VM.
I will try the older version of Virtualbox and get back to you if it works again.
Thank you!

It will be. AIUI VirtualBox 7 can't run any other way on MacOS. It doesn't support older versions of MacOS, i.e. no fallback to earlier hypervisors and kexts.
