Virtual Laboratory Environment - Systems Administration and Maintenance

These flashcards cover key concepts and information related to virtualization, Oracle VirtualBox, its features, installation needs, and networking configuration.

What is virtualization?

Virtualization is the process of creating a virtual version of something, such as an operating system or server, allowing multiple operating systems to run on a single physical machine.

What are the benefits of virtualization?

The benefits of virtualization include cost savings, improved resource utilization, isolation, flexibility and scalability, and enhanced disaster recovery.

What is Oracle VirtualBox?

Oracle VirtualBox is a free and open-source virtualization software that allows users to run multiple guest operating systems on a single host machine.

What are some key features of Oracle VirtualBox?

Key features include cross-platform support, Guest Additions, snapshot support, shared folders, and remote display.

What are the hardware requirements for installing Oracle VirtualBox?

The hardware requirements include an x86 or x86-64 processor, at least 2 GB of RAM, and around 200 MB of free disk space.

What networking modes does Oracle VirtualBox offer?

Networking modes include NAT, Bridged Networking, Internal Networking, Host-Only Networking, and NAT Network.

What is the purpose of snapshots in Oracle VirtualBox?

Snapshots provide a point-in-time image of a VM's state, allowing users to backup, test configurations, rollback, and develop software.

What is cloning a virtual machine in Oracle VirtualBox?

Cloning creates an exact duplicate of the original VM, including disks and settings, which is useful for testing and resource management.

What is the purpose of network address translation (NAT) in VirtualBox?

NAT allows the VM to share the host's IP address, enabling access to external networks while remaining invisible to other machines.

What operating systems are supported as host systems for Oracle VirtualBox?

Supported host operating systems include Windows (7, 8, 10), macOS (OS X 10.10 or later), various Linux distributions, and Solaris.
