Virtual networking in KVM environments is foundational for enabling communication between guest VMs, the host, and external networks. This guide covers core concepts and practical implementations—including Linux bridges, NAT-based and bridged virtual networks, and resilient bonded interfaces—using modern libvirt tooling and kernel-native mechan ...

To perform hot resizing operations on a KVM virtual machine, the virtual machine must be initially configured with parameters that define its maximum capacity. This guide demonstrates how to dynamically adjust disk, network, memory, and CPU resources without shuting down the guest operating system. Disk Hot Resizing 1.1 Hot-Adding a New Disk Fi ...
