Or using virt-manager.

This script ensures that the node will be recognized and start correctly.

: In highly-utilized hypervisors, explicitly reserve CPU and memory cycles for this VM to prevent jitter or packet loss on critical network tunnels. If you are planning to deploy this image soon, let me know:

Because it boots a complete enterprise operating system, this image is resource-intensive. Attempting to cut corners on allocations will cause the virtual switch to crash during bootup or drop into a continuous reboot loop. Recommended Specification 4 vCPUs (Minimum) System RAM 18 GB RAM per node Disk Size ~2.7 GB (Compressed package size) Ethernet Interfaces Up to 25 ports (1 Management + 24 Dataplane) Supported Features vs. Lab Constraints Or using virt-manager

One "interesting" piece of trivia about the cat9kv images is their ability to use hardware offload adapters. If you run this qcow2 in a server equipped with an Intel Fortville or Columbia 4G adapter, the switch can use SR-IOV to bypass the hypervisor CPU for data plane traffic. This gives the virtual switch near-line-rate performance, which is rare for virtualized network gear.

The .qcow2 format makes this image highly versatile across multiple environments: Type 1 Hypervisors (KVM & OpenStack)

However, being a virtual switch, it has limitations in throughput (typically 1–10 Gbps depending on CPU) and does not support hardware-specific features like UADP ASIC offload.
