VMkernel Protection - To protect the hypervisor from common attacks and exploits, mechanisms were introduced to assure the integrity of the VMkernel and loaded modules as they reside on disk and in memory. Disk integrity techniques protect the boot-up of the hypervisor by utilizing the Trusted Platform Module (TPM), a hardware device embedded in servers. p To ensure the authenticity and integrity of dynamically loaded code, VMkernel modules are digitally signed and then validated during load. p These disk integrity mechanisms protect against malware, which may attempt to overwrite or modify VMkernel as it persists on disk. VMkernel also uses memory integrity techniques at load-time coupled with microprocessor capabilities to protect itself from common buffer-overflow attacks used to exploit running code. These techniques create a stronger barrier of protection around the hypervisor. VI 4 - Mod 0 - Slide 41

Virtual Machine Communication Interface (VMCI) - ESX/ESXi 4. 0 introduces a new virtual device which facilitates high-speed communication between the virtual machine and the hypervisor as well as between virtual machines.
