Upon first boot, the router will initiate the "Cisco Software Configuration Dialog." Select to configure the unit manually via standard IOS-XE commands.
: Corresponds to Cisco IOS XE release 17.12.1 (Dublin) .
Once booted, the image prompts for standard setup initialization. Below is an optimized baseline configuration enabling secure SSH access and modern management interfaces.

Official Cisco images are typically named like cat9kv_iosxe.17.12.01.SPA.qcow2 . The prd9 and extra prd in your string suggest a non-release or engineering build.
To achieve predictable throughput and prevent packet drops, the hypervisor must guarantee specific compute allocations. Performance Tier vCPUs (Minimum) RAM (Minimum) Target Throughput Up to 100 Mbps Medium Branch Up to 1 Gbps Large Enterprise/Hub Hypervisor Recommendations Upon first boot, the router will initiate the
