Kernel-based Virtual Machine (KVM) is a virtualization infrastructure for the Linux kernel that turns it into a hypervisor. It was merged into the Linux kernel mainline in kernel version 2.6.20, which was released on February 5, 2007. • Pro and Cons of KVM • Benefits/Features • Performance and Scalability – KVM provides near native performance which makes it a scalable solution. • Lower cost – As open source, no vendor lock-ins, maintaining the virtualization infrastructure is easy. • Secure – KVM supports the security features such as selinux to make it secure. • Note - There is no guarantee to any hypervisor that they are bug free. • Supports live/offline VM migration – This feature helps when any maintenance is planned on the KVM host. • Full Virtualization - KVM is a full virtualization technology as opposed to para-virtualization techniques thus no modifications are needed in the guest operating systems. • Opensource – KVM is opensource software and maintained by a large Opensource Developer Community. • Various Filesystems Support - KVM supports all type of filesystems supported by the mainstream Linux kernel. • Resource over-committing - which allows you to allocate more virtualized CPUs and memory than available resources on the host. The VMs then only use what they need, allowing other VMs to use unused resources • Drawbacks • Supported by certain processor types. https://www.linux-kvm.org/page/Proces... • Complex Networking. • Watch the video for details:
