ABSTRACT:
A system and method for a virtualization aware hard drive. A method may include issuing a context command and an input/output (I/O) command by a virtual machine to either a hardware controller or a virtual machine monitor (VMM). The controller (or VMM) fills in a context tag that corresponds to the context command and the I/O command. The controller (or VMM) provides the context tag and the I/O command to a virtualization aware hard drive. The context tag provides context to the hard drive for the I/O command. Other embodiments are described and claimed.
