Kernel-based Virtual Machine or KVM is a simulated platform for Linex kernel that converts it into a hypervisor. It was amalgamated in kernel version 2.6.20 into the Linux kernel mainline. It requires a processor that comes with hardware virtualization extensions. In the last decade, virtualization has gained popularity due to the development of open source virtual machine hypervisors.
There are several advantages and benefits of KVM Virtualization. Some of them are:
KVM is a full virtualization technology, therefore, no modification is needed in the guest operating system. It can easily support proprietary operating systems such as windows, and Linux without making any changes to them. The memory virtualization capability of KVM shows the full address space to the guests.
According to the recent market analysis, KVM is 60 to 90% less expensive than other solutions available in the market and offers the same level and number of functionality as other solutions offer. KVM is also value for money can effectively provide beneficial functionality that all businesses, whether big or small, can easily afford. By opting for KVM, companies can easily enjoy a large number of benefits at the cheapest rates.
As KVM is based on Linux, it uses advanced level of security which provides Mandatory Access Control (MAC) security among the virtual machines. It has also been awarded for meeting the security standards set by the government.
Open to all
KVM can be easily customized depending on a person’s requirements. The open environment of KVM does not limit the users unlike most of the other proprietary solutions available.
KVM is the default hypervisor in Linux. KVM automatically reflects new features and improvements to the Linux kernel thus making it an even more interesting solution.
