When I want to specify passwords on command line I usually do something 
like:

read p
qemu ...,$p

That makes sure it's not stored in the history.

You can as well use read p < afile

If you really don't want to have the string as part of the environment 
you can try command substitution...

qemu ...,$(cat afile)

Alike, the real password won't be stored inthe history.

man bash should help :)
