NewQemuBuilder creates a new QemuCmd object that we will build on top of, starting with the qemu binary, architecture specific options, and propagated proxy and SSL settings.

NewQMPMonitor creates the monitor subsection of our vm.

Deprecated: MachineVMV1 is being deprecated in favor a more flexible and informative structure.

QemuCmd is an alias around a string slice to prevent the need to migrate the MachineVM struct due to changes.
