Hi, unfortunately, I and a few others on this list have found qemu to be 
unreliable on an ARM host. There are a number of cases where an emulation that 
runs well on an x86 host fails in odd ways when moved to an ARM host.  This 
_seems_ to affect 64 bit guests more than 32 bit guests, but it is difficult to 
prove at the moment.

Another aspect seems to be whether you are using qemu-system or qemu-user.  I 
for example use qemu-user successfully for running some x86-64 linux apps that 
have no ARM port, but I've never been able to get qemu-system to boot MIPS, 
SPARC, or x86 images.

My best suggestion is to try and see if it will work for your specific 
application or not.
