KVMn

KVMn refers to Kernel-based Virtual Machine with n as a variable number. In the context of Linux virtualization, KVM is a widely adopted technology that allows the Linux kernel to function as a hypervisor. This means that KVM can create and manage virtual machines directly on a host machine. The "n" in KVMn typically signifies the number of virtual machines being managed or the specific configuration being employed. For instance, one might refer to a KVM setup managing 3 virtual machines as KVM3, although this is not a standard formal designation.

The core of KVM is its integration with the Linux kernel, leveraging hardware virtualization extensions like Intel VT-x and AMD-V. This allows for near-native performance of virtualized guest operating systems. KVM, as a kernel module, provides the necessary virtualization infrastructure, while user-space components like QEMU are used to emulate hardware for the virtual machines. When referring to KVMn, the focus is often on scaling a KVM deployment, managing a certain quantity of virtual machines, or perhaps a specific network topology involving multiple KVM instances. The precise meaning of "n" can vary depending on the context of the discussion, but it generally implies a quantity or a specific instance within a larger KVM environment.
