Techniques for memory de-duplication in a virtual system are described. An apparatus may comprise a first processor circuit coupled to a second processor circuit. A memory unit may be coupled to the first processor circuit and the second processor circuit, the memory unit to store private memory pages and shared memory pages for multiple virtual machines. A memory management application may be operative on the first processor circuit and the second processor circuit in a shared manner to perform memory de-duplication operations on the private memory pages stored in the memory unit to form shared memory pages. The memory management application may perform sequential memory de-duplication operations on the first processor circuit, and parallel memory de-duplication operations on the second processor circuit. Other embodiments are described and claimed.
