An existing neutral operating system (OS) signal is utilized to notify a virtual
machine (VM) about a change to its execution parameters. The signal is predefined
to indicate that an execution parameter should be changed, and upon receipt, the
VM may look up a file in a predefined location, the file containing the new command
line parameters. The VM may then modify its parameters to match the file, and continue
with its execution, thus providing a mechanism for altering VM execution parameters
at runtime.
