Error: failed to open a session for the virtual machine

Error: failed to open a session for the virtual machine

I have a new MacBook Air (M1, 2020)
Processor: Apple M1
8 GB RAM
MacOS Big Sur v. 11.4

I installed a virtual box. I created a virtual machine with 8 GB of RAM and a 50 GB hard drive.
The virtual machine is running windows 10.

When I try to start the virtual machine, I get an error that says “failed to open a session for the virtual machine VM1 windows 10.
The result code is: NS_ERROR_FAILURE
Component: MachineWrap
Interface/ Machine

What is wrong? When I installed virtual box on my Windows machine, I had no problems.

Thank you very much,
Paolo Barone

An M1 Mac cannot run Virtualbox. Please see the sticky on the top of Mac Hosts, viewtopic.php?f=8&t=98742
