I downloaded the VMware fusion for my M1 and prompted an "Upgrade ... " Dialog box. I accepted, and it froze me in my tracks. My error code is KB-84273. Feel free to reach out here or via my Twitter: LandoWRLD.
Which Guest VM you were trying to run? Is it x86 or ARM?
Was the full error something like this:
"This virtual machine cannot be powered on because it requires the x86 machine architecture, which is incompatible with this arm machine architecture host. See KB-84273.
Please note only ARM Guest VMs are supported run on this.
Please try ARM Guest with any of the supported Guest OS Matrix and ideally you shouldn't get any
Let us know how it goes.
The entire error message you gave was correct. Although, I do not remember what version I was trying to run. I used VMware for my previous mac to run windows, and I tried the same process a few weeks ago on my M1. When I loaded up the Silicon-based software, it looked like it already had a windows of some kind installed.
Intel Macs can only run x86-based OSes with Fusion.
M1 Macs can only run ARM-based OSes with Fusion.
So if you have an x86-based VM from an Intel Mac, you can't run it on an M1 Mac.
