[FAQ] What Are KVM Advantages

Hello,
A hardware device installed in the integrated configuration cabinet. KVM serves as the input and output device for the components inside the cabinet. It consists of a screen, a keyboard, and a mouse.

Have a nice day!
Compared with the Xen architecture, KVM has the following advantages:
 Better ecosystem
− Well-known organizations, such as OpenStack and OVA, safeguard KVM. OpenStack provides the best support for KVM. Currently, over 95% of OpenStack platforms are driven by KVM.
− All NFV vendors require that the KVM platform be used.
− KVM is deeply integrated with the Linux kernel. Hardware features good compatibility with the help of extensive ecosystem of the Linux kernel.
− KVM is the most active open source virtualization community.
 Better architecture
− KVM supports the hardware-assisted virtualization technology and is the first to use such technology. With the help of the Linux baremetal kernel, no PVOPS performance loss occurs.
− KVM is a part of the Linux kernel and is deeply integrated with the kernel. KVM can reuse complete code, such as process scheduling, memory management, and I/O management, in the Linux kernel.
− KVM utilizes the mature and progressive Linux kernel technologies for a long time, optimizing KVM implementation.
 Better performance
− The KVM-based design focuses on enterprise-grade performance.
− According to SPECvirt, a third-party authoritative test, KVM outperforms Xen in performance.
− Hypervisors are not required for access to and mapping of shared areas between VMs and between a VM and the host kernel. Therefore, the entire access path is shorter, and the architecture is better.

Hope can help you!

Although the majority of the virtualization software industry is dominated by VMware, KVM market is growing massively because of it's one major advantage over the rest of paid license based virtualization software and that is it provides the agility and flexibility to shape it according to your needs. KVM has an ever-growing community, that is one of the big reasons that many data centers are adopting this technology.

Many companies have adopted this technology and are giving their customers the ability to utilize agility of KVM, one such example is StoneFly who have recently integrated the support of KVM into their storage virtualization software SCVM.

Apart from that, many software enterprise companies are selling the commercial version of KVM. They have modified and added new features to cater to the needs of their customer. On such example is Nutanix AOS which has a built-in KVM based hypervisor AHV.
