SANS security expert Jake William warned, "Meltdown may target kernel addresses that are shared between the container and host kernel in many paravirtualization instances (e.
Previous implementations are mostly based on paravirtualization because the hardware architectures do not fulfill the requirements for a full-virtualization of the Popek & Goldberg theorem [1].
In cloud computing, we're interested in techniques such as paravirtualization, which allows a single server to be treated as multiple virtual servers, and clustering, which allows multiple servers to be treated as a single server.
There are three common ways to expose a device to a guest: emulation, paravirtualization and pass-through (Figure 5).
It is hypervisor is considered a solution based paravirtualization, because guest systems must be modified to cohabit [7].
SierraVisor's paravirtualization technology minimizes modifications to existing software and applications.
75) Though this makes some applications such as streaming video difficult to replicate, two solutions are possible: (1) institute paravirtualization (hybrid virtual machines) to directly access hardware for some functions to provide processing speed increases; and (2) employ faster processors.
An alternative to full virtualization with hardware assist is provided by paravirtualization.
