I recently created a macOS VM (Ventura 13) with VirtualBox (Version 7.0.6 r155176 (Qt5.15.2)). I first launched it with one CPU, and it booted. The downside was that the VM was very slow and practically unusable, so I set the number of CPUs to 4 (i have 8 in total). It won't boot up. After some tests I figured out that if I set the CPUs to more than one, the VM starts, restarts while booting and finally VirtualBox gives me the Guru Meditation error : "A critical error has occurred while running the virtual machine and the machine execution has been stopped."
Can someone tell me how to use the VM with more than 1 CPU ?
Here are the logs
