: Denotes the lightweight, 32-bit virtualized version of Cisco’s IOS XR operating system.
The string "iosxrvk9demo613qcow2" likely refers to the filename iosxrv-k9-demo-6.1.3.qcow2 , which is a virtual disk image for the Cisco IOS XRv
This is an older release (6.1.3 was End-of-Life / End-of-Support several years ago). While stable for legacy labs, it lacks newer features found in IOS XR 7.x and 24.x (such as Smart Licensing, newer YANG models, and containerized apps).
When you see a .qcow2 file, you typically boot it with:

The original image had been a .vmdk from a VMware build, but Elias had already run the conversion: qemu-img convert -f vmdk -O qcow2 iosxrv-demo.vmdk hda.qcow2 .The QCOW2 format was his secret weapon—it supported "copy-on-write," meaning it was lean, fast, and allowed him to take snapshots before making risky configuration changes.

in QCOW2 format. This image is a cornerstone for network engineers and students who need to simulate the Cisco IOS XR operating system—the high-end software typically found on carrier-grade routers like the ASR 9000 or NCS series. What is IOS XRv?
: Refers to Cisco's lightweight, 32-bit virtual IOS XR image designed primarily for control-plane testing.
: Indicates the inclusion of strong cryptographic features (SSH, HTTPS, IPsec, and advanced routing security) subject to export controls.
