No, it doesn't make a difference.

Note that it shutdowns fine (including qemu process) when the guest is x86.

With an ARM guest, qemu keeps running. Perhaps the guest needs something 
in the kernel? I added APM, but it didn't make a difference.


When the guest is halted, this is what I get when I strace the 
qemu-system-arm process (endlessly in a loop):

sigreturn()                             = ? (mask now [])

select(8, [5 7], [], [], {0, 10000})    = ? ERESTARTNOHAND (To be restarted)
