Abstract
Systems and methods for virtual machine communication in a virtualized environment can include identifying an encrypted guest memory location of a virtual machine (VM), the encrypted guest memory location associated with a virtual device, and copying a first set of encrypted data from the encrypted guest memory location to hypervisor memory to create a copied set of encrypted data. They can also include comparing a second set of encrypted data from the encrypted guest memory location with the copied set of encrypted data, and responsive to detecting a difference between the second set of encrypted data and the copied set of encrypted data, requesting, unencrypted data comprising a request related to the virtual device.
