When you want to store several separate arguments, do not combine them
into a single string.
Compare this
args="-a 'hello world' -b '1 * 3'"
printf '"%s"\n' $args
and
args=( -a 'hello world' -b '1 * 3' )
printf '"%s"\n' "${args[@]}"
Using an unquoted variable

shell separates between spaces and quotes
u need quoting right, otherwise its flat args or one arg if quoted not right
arr=( -arg{1,2,3} )
cmd "${arr[@]}"
tells to pass every arr member with quotes

I hava run into some troubles when I use bash shell to execute qemu, here is
the log.
1. Run qemu with arguments directly in bash shell, I use strace to track
execve syscall, everything goes well
