Question

Paravirtualization is ideal for? (1) Automatic failure detection (2) Computer system sharing, isolate users (3) Data replication (4) Disaster recovery, migration capacity

Answer 1

Answer: (2) Computer system sharing, isolate users

Paravirtualization is the expansion of the technology of virtualization in which a guest operating system (OS) is recompiled within a virtual machine before installation.

• Paravirtualization is created to allow many programs, through the efficient use of computing resources including processors and memory, to operate on a single hardware package.
• To function with a virtual machine, the OS is usually changed.
• It helps the guest operating system to be notified that it is a guest and has a driver which does not send commands directly to the hardware, but offers the host system commands respectively.
