Study Notes
- Running multiple operating systems on one desktop can be achieved through virtualization.
- Virtualization allows running different OSs without creating partitions or rebooting.
- A hypervisor manages resources (memory, storage, networking, etc.) for each virtual machine.
- Intel CPUs have virtualization technology (VT), AMD CPUs have AMD-V.
- Virtualization requires sufficient RAM for all operating systems.
- Virtual machines need sufficient storage space for installation and data.
- Virtual machines need proper network configurations.
- Virtualization is useful for application development through isolated testing environments.
- Virtualization enables creating snapshots of VM configurations for easy restoration.
- Security is a concern in virtualized environments, with VM escaping being a major threat.
