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.
