Distinguish between Machine and operating system virtualization.
Let us learn about machine virtualization.
Machine Virtualization
The diagram given below shows the machine virtualization −
Operating system virtualization
The diagram given below shows the operating system virtualization −
Differences
The major differences between Machine virtualization and operating system virtualization are as follows −
| Machine virtualization | Operating system virtualization |
|---|---|
| It refers to the creation of a virtual machine that acts like a real computer. | It is a part of virtualization and is a type of server virtualization. |
| It can be done by extracting the physical
hardware with the help of VVM (Virtual
Machine Monitor). | With OS virtualization nothing is pre
installed/ permanently loaded on the local
device & no hard-disk drive is needed. Everything runs from the network using a kind of virtual disk. |
| Full virtualization, emulation virtualization,
Para-virtualization are the types of machine
virtualization. | Linux OS virtualization, windows OS
virtualization are the two types of OS
virtualization. |
| Concept Shared hardware is installed on a virtual machine monitor (VMM) or called a hypervisor. Virtual box, Vmware workstation and HyperV are installed on these hypervisors & we can install different virtual machines in this particular hardware. All virtual machines have different applications. | Concept In the host hardware we are installing the host operating system. The hypervisor/virtual box/Vmware workstations are first installed into a full host operating system. With this software we can install more than one operating system in the machine. |
| Advantages Controlling a virtual machine is much easier than controlling a physical machine. Lower cost. Efficient resource utilization. | Advantages OS virtualization is capable of live migration. Usually impose little or no overhead. It can also use dynamic load balancing of containers between nodes & clusters. |
