Iosxrv-k9-demo-6.1.3.qcow2
To most, it was just a virtual disk image, a piece of software used to simulate a Cisco IOS XRv router . To Elias, it was a gateway.
The file iosxrv-k9-demo-6.1.3.qcow2 represents a specific, widely used demonstration image of Cisco's 32-bit IOS XRv operating system, version 6.1.3, formatted for Quick Emulator (QEMU) environments. What is iosxrv-k9-demo-6.1.3.qcow2 ?
One of the main reasons engineers still use version 6.1.3 is its efficiency. It requires significantly less power than the 64-bit , making it ideal for large topologies on standard laptops. Requirement Recommended Value 3072 MB (3 GB) vCPU Disk Space ~430 MB (compressed file size) Hypervisor KVM (Required for GNS3/EVE-NG) How to Use the Image in Your Lab 1. GNS3 Integration
| Feature | Demo Version Status | |---------|---------------------| | | Works (routing protocols like OSPF, BGP, ISIS) | | Data Plane | Does not forward traffic (no ping through, no IP forwarding) | | Interface Count | Typically limited to 2-3 interfaces | | License | No license required, but expires after 60 days of uptime | | VRF | Limited or non-functional | | MPLS/LDP | Basic control plane only, no forwarding | Iosxrv-k9-demo-6.1.3.qcow2
: Runs the 32-bit Cisco IOS XR software on a QNX microkernel.
: This signifies Cisco IOS XR Virtual. It is a representation of Cisco's high-end Service Provider operating system (IOS XR), adapted to run as a virtual machine on standard x86 hardware.
This is a "demo" image. It has throughput capping (usually limited to 2 Mbps or less) and is not intended for production traffic. To most, it was just a virtual disk
The most interesting aspect of this file today is how it changed how engineers work.
