The iosxrv-k9-demo-6.1.3.qcow2 image packages a single-CPU instance combining both Route Processor (RP) and Line Card (LC) functionality into a compact virtual machine (VM) footprint. It bypasses the need for high-end multi-core hardware allocations typical of production-grade Cisco virtual routers, like the massive Cisco IOS XRv 9000 series .
This is critical because older templates might try to launch the VM with the wrong RAM or CPU settings, or the wrong network adapter type (e.g., using E1000 instead of VirtIO), causing the router to crash. The "update" signifies that the software now supports that specific version natively. iosxrvk9demo613qcow2 updated
