Advanced Topic 45 of 51 Operating Systems
Virtualization
Running multiple isolated systems on shared hardware.
How it works
Virtualization abstracts hardware so several operating systems run on one machine. CPUs have hardware support (VT-x, AMD-V) to run guests near native speed.
Where it is used
Cloud servers, testing environments.
Common pitfall
Overcommitting resources reduces performance.
Where it fits in the course
Virtualization is topic 45 of 51 in Operating Systems, rated Advanced. It follows Real-Time Operating Systems. The next topic is Containers.
