Hellow @nongiach
I encountered some errors when I created the virtual machine using arm_now. Can you help me to fix this error? "FileNotFoundError: [Errno 2] No such file or directory: 'e2rm': 'e2rm'"
And here are traceback log ：

I'm sure I installed all the dependencies, but I still can't create the arm virtual machine.
Can you help me?
Thank you
Please

@Uniqu3Ch1 If you still have some issues, you should install e2tools.
