Greetings,
The 32 bit ARM VMs work for v6 & v7.
The 64 bit VM is for v8/AArch64 on Linux. This is only the interpreter
VM (no COG JIT), so is pretty slow currently. Also the UFFI is not yet
working on 64 bit. I am working on this but am a bit slow at it.
I would suggest the 32 bit VM for now as the UI is faster.
I don't know if the 64 bit ARM VM is built by default. I can help with
advice if you run into problems building from sources.
