KVM Hypervisor’s Advantages and Disadvantages

What is KVM Hypervisor?

KVM hypervisor offers complete virtualization features. Each virtual machine (VM) is given access to all of the standard physical system functions, including a virtual BIOS (basic input/output system) and virtual hardware (CPU, memory, storage, network cards, etc.).

Let’s look into the advantages and disadvantages of the KVM hypervisor.

KVM Hypervisor’s Advantages

1. Since KVM makes use of hardware virtualization extensions like Intel VT or AMD-V, VM performance is close to native. Direct access to the underlying hardware is possible, leading to effective and quick virtualization.

2. Large-scale virtualization environments are supported by KVM. It is useful for consolidating workloads and maximizing resource usage because it can host many VMs on a single physical host.

3. Full virtualization is available with KVM, allowing VMs to run unmodified operating systems like Windows, Linux, and others. We can virtualize a variety of operating systems and apps thanks to this versatility.

4. KVM ensures that each VM functions independently of the others by providing robust isolation between them. By reducing the chance that one VM could compromise the others, this isolation improves security. As part of the development of the Linux kernel, KVM also gains from frequent security upgrades and patches.

5. The Linux community actively develops and maintains KVM, an open-source technology. Due of its enormous user base, there are numerous resources, documentation, and community support services available.

KVM Hypervisor’s Disadvantages

1. KVM and the Linux kernel work together seamlessly. This benefits Linux-based systems, but it may also reduce their interoperability with other operating systems. Although KVM can virtualize Windows and other operating systems, Linux is the main emphasis and the subject of most development work.

2. KVM might be more difficult to set up and configure in comparison to some alternative hypervisor systems, especially for people with less experience with Linux and virtualization technologies. For efficient maintenance, a thorough understanding of the underlying system and familiarity with Linux command-line tools may be necessary.

3. The environment for GUI-based management of KVM is not as developed as that of other hypervisors like VMware or Hyper-V, despite the fact that some graphical management tools are available for KVM. The majority of KVM management is done using scripting and command-line interfaces.

4. KVM depends on extensions for hardware virtualization, therefore it might not work with outdated CPUs or systems that don’t have the requisite virtualization capabilities. Before using KVM as a hypervisor, it’s critical to make sure your hardware is compatible with it.

5. KVM has community support, however, compared to proprietary hypervisors, it might have less focused business support. Alternative solutions might be preferred by organizations looking for comprehensive vendor support alternatives.
