Help to run assembly code

[Isac Monção <isacmoncao%disroot.org@localhost>]

Hi everyone

I'm learning assembly, but I can't manage to run the linked binary. 
It keeps saying "sh: Cannot execute ELF binary ./hello". I even
loaded the compat_linux kernel module. Does anyone know what I'm
forgetting?

_start:

  mov rdi, 1            ; file descriptor: stdout
  mov rsi, msg          ; buffer address
  mov rdx, len          ; buffer length
  syscall

  ; exit syscall
  mov rax, 1            ; NetBSD x86-64 syscall number for exit
  mov rdi, 0            ; exit code 0
  syscall               ; invoke syscall
