Virtualization Technology
Tools of the Trade: Linux and SQL (module1)
Managing Virtual Machines
Hypervisor
Software that manages VMs and connects virtual/physical hardware.
Example: KVM (Kernel-based Virtual Machine), built into Linux kernels.
Allocates shared resources.
Other Forms of Virtualization
Virtual Networks: Efficient use of physical network hardware.
Virtual Servers: Multiple virtual servers from one physical server.
Benefits of Virtual Machines
Security:
Isolated environment (sandbox) protects host and other VMs.
Allows testing malware securely.
Note: Malware can still escape, posing risks.
Efficiency
Run multiple VMs on one physical machine.
Streamlines security tasks (e.g., testing, switching between environments).
