By making the error reporting include strerror(errno), it gives the user
a bit more indication as to why qemu failed.  This is particularly
important for people running qemu as a non root user.

The neat being that some of the conditions under which this code runs
do set errno while others have nothing to do with it..
Yeah but I figured that a bad errmsg is more useful than nothing.

Getting errno to be reliable is tough because in these paths, there are various function calls that can throw off errno.
