[3] [4] Finally, with a multi-core or multi-processor physical host, it is possible to deploy each VM on a separate processor or core to temporally isolate the performance of various VMs. For the network, it is possible to use traffic shaping techniques to limit the amount of traffic that each VM can impose on the host.
The project maintains around 100 virtual appliances, all freely licensed, with daily automatic security updates and backup capabilities. [2] They are packaged in formats for different virtualization platforms, and two builds for installing onto physical media (to non-virtualized hard disk or USB from a hybrid ISO) or onto the Amazon Elastic Compute Cloud.
Because this code contains many privileged instructions which cannot run natively in ring 1, VirtualBox employs a Code Scanning and Analysis Manager (CSAM) to scan the ring 0 code recursively before its first execution to identify problematic instructions and then calls the Patch Manager (PATM) to perform in-situ patching. This replaces the ...
Instruction set extensions that have been added to the x86 instruction set in order to support hardware virtualization.These extensions provide instructions for entering and leaving a virtualized execution context and for loading virtual-machine control structures (VMCSs), which hold the state of the guest and host, along with fields which control processor behavior within the virtual machine.
Guests can have multiple virtual CPUs, the maximum number in supported configurations being 4 with releases before 4.0, then 8 with release 4.0, 16 with release 4.3, and 32 with 6.3. Guests can be configured with up to 256GB of memory in version 6.3. In recent releases, memory can be adjusted dynamically for HP-UX guests.
Nested virtualization becomes more necessary as widespread operating systems gain built-in hypervisor functionality, which in a virtualized environment can be used only if the surrounding hypervisor supports nested virtualization; for example, Windows 7 is capable of running Windows XP applications inside a built-in virtual machine.

In software engineering, containerization is operating-system–level virtualization or application-level virtualization over multiple network resources so that software applications can run in isolated user spaces called containers in any cloud or non-cloud environment, regardless of type or vendor.
