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
