This program is a launcher that prevents multiple instances of QEMU to run simultaneously as well as pulling the appropriate command line arguments from a configuration file.
QEMU is not protected by a startup mutex and multiple instances can be launched simultaneously, this may corrupt the disk image that is being used. This small utility launches QEMU with a named mutex and prevents further instances from being launched simultaneously. In addition to this, the many command line arguments passed to the binary can conveniently be stored in a configuration file.
Create an ini file named i.e. qemu-control.ini with the following contents and launch QEMU Control with the filename as argument.
