superqemu/examples/simple.js

// A simple/contrived? example of how to use superqemu.
//
// Note that this example requires a valid desktop environment to function
// due to `-display gtk`, but you can remove it and run it headless.
//
// Also note that while superqemu automatically sets up QEMU to use VNC,
// it does not provide its own VNC client implementation.
