Virtualization Concepts 4.2 Flashcards
- Host computer installed with a hypervisor that can be used to install and manage multiple guest operating systems or virtual machines
- the heart of cloud computing
Virtualization
Runs within the normal operating system
Type II Hypervisor
Runs directly on the host hardware and functions as the operating system
Type 1 Hyper (Bare Metal)
_____ solution that allows an application to be packaged up and streamed directly to a user’s PC
Client-based (Application streaming)
______ solution that runs the application on servers in a centralized location
Sever-based (Terminal services)
Manages the distribution of the physical resources of a server to the VMs
Type I (bare metal) & Type II (Hosted)
Encapsulates computer programs from the underlying OS on which they are executed
Application virtualization
Hosts desktop OSs within a virtualized environment hosted by a centralized server or server farm
Virtual Desktop Infrastructure (VDI)
Type of virtualization applied by a host operating system to provision and isolated execution environment for an application
Container-based virtualization (Containerization)
an isolated environment for analyzing pieces of malware
Sandbox
Allow for the testing and running of software applications for different operating systems
Cross-platform virtualization
system imitation
Emulation
new “physical” machine
Virtualization
Improves the performance of virtual memory when running multiple virtual machines on a single physical host
Second level address translation (SLAT)
SLAT for intel is known for
Extended Page Table (EPT)
Reduced instruction set and computer architecture in a computer processor
ARM
SLAT for AMD is known for
Rapid Virtualization Indexing (RVI)
Amount of physical memory installed on a physical server
System memory
____ installation takes 20-50 gigabytes of space
Barebones Windows
__ environment takes 20-40 gigabytes of space
Mac
___ allows multiple cards for higher speeds
NIC teaming configuration
- Threat attempts to get out of an isolated VM and send commands to the underlying hypervisor
- VM to hypervisor or host OS
VM Escape
- Threat attempts to move from one VM to another on the same host
- VM to VM
VM Hopping
VM escape is easier to perform on a ___ than a ___
- Type II hypervisor
- Type I hypervisor
