Need to know more about KVM hypervisor ?
This is the guide.
Kernel-based Virtual Machine (KVM) is an open source virtualization technology built into Linux. Specifically, KVM lets you turn Linux into a hypervisor that allows a host machine to run multiple, isolated virtual environments called guests or virtual machines (VMs).
You might be wondering if Linux and Windows virtual machines run side by side on the same hardware.
The fact is that it is possible using KVM virtualization. And, KVM hypervisor is the main factor that makes this virtualization possible.
Here at Ibmi Media, as part of our Server Management Services, we regularly help our Customers to perform Virtualization related tasks.
In this context, we shall look into on how the KVM hypervisor works.
Nature of KVM and hypervisor ?
Virtualization allows us to use a physical machine’s full capacity by distributing its capabilities among many users or environments.
And, it can increase IT agility, flexibility, and scalability while creating significant cost savings. And, KVM is one of the best virtualization techniques.
KVM Virtualization is a leading open-source complete virtualization solution. It supports all major operating systems including Linux and Windows.
And, it allocates separate virtual computing resources for each virtual machine such as the processor, storage, memory, etc.
Now, have any idea about how does KVM hypervisor support this virtualization?
More about Hypervisor ?
Basically, the functions of the hypervisor enable virtualization.
So, the function of partitioning, abstracting, and isolating different OS and applications from the underlying computer hardware is what the hypervisor does.
Also, hypervisor helps manage independent Virtual Machines by distributing hardware resources such as memory allotment, CPU usage network bandwidth, and more amongst them.
In short, hypervisor helps VMs to connect with one another.
How KVM hypervisor works?
Basically, there are mainly two types of hypervisors. Type 1 or Native hypervisor and Type 2 or hosted hypervisor.
Type 1 hypervisors run on the host machine’s hardware directly. This means the hypervisor has direct hardware access without contending the OS.
And, Type 2 hypervisors rely on top of operating systems. Because of this reason, these are known as Hosted hypervisors.
Also, it supports multiple guest machines but cannot directly access host hardware and its resources.
And, KVM has a unique hypervisor that has the characteristics of both Type 1 and Type 2 hypervisors.
