Hi, When I try to run more than 2 virtual machines with macOS 12 ARM, I get this error: "No value exists in nvram for the provided key. The maximum supported number of active virtual machines has been reached". This error occures only for mac ARM. (I tried to set less cpu_cores and ram_size for vms but I get the same error). There is a method to run more vms for mac ARM ?
I was getting this error when trying to launch a macOS13 guest on a macOS12 host (ARM), with no other VM running. That VM was working normally till a couple of days ago. A reboot of the host fixed the issue, but maybe it was not the same problem you are facing...
