Unpacking the "iosxrvk9demo613qcow2 exclusive": What It Is and Why It Matters
iosxrvk9demo-6.13.0.qcow2 (or your iosxrvk9demo613qcow2 shorthand) is a QEMU Copy-On-Write disk image of Cisco’s IOS XRv 9000 – a virtual route processor for the IOS XR operating system.
A write-up for the iosxrv-k9-demo-6.1.3.qcow2 virtual appliance involves its configuration and deployment in network emulation environments like . This specific image is a demo version of Cisco's
, a virtualized platform for the IOS XR operating system typically used for labbing and testing Service Provider features. Cisco Community Key Specifications & Limitations RAM Requirement : 3072 MB (3GB) minimum. Hypervisor : Requires
(Linux) or a GNS3/EVE-NG VM with nested virtualization enabled. Data Plane Limit
: As a demo version, throughput is typically rate-limited to Credentials : Default login is often
with no password, though some versions require setting credentials on the first boot. Deployment Steps
The following steps outline how to implement this image in common lab environments: Preparation : Ensure the file is named exactly iosxrv-k9-demo-6.1.3.qcow2 to match standard appliance templates. MD5 Checksum
: The 6.1.3 image should be verified if a checksum is provided by your source. Environment-Specific Setup : Import the corresponding
appliance file. Select the version "6.1.3" and point the software to your Create a directory: /opt/unetlab/addons/qemu/iosxrv-6.1.3/ Upload and rename the image to virtioa.qcow2 inside that folder. Run the EVE-NG permission fix command: /opt/unetlab/wrappers/unl_wrapper -a fixpermissions Vagrant/Libvirt : You can use conversion scripts (like create_box.sh ) to turn the file into a Vagrant box for automated lab deployment. Booting and Configuration
The first boot may take several minutes as the IOS XR kernel initializes. Two-Stage Configuration
: Unlike standard IOS, changes in IOS XR must be "committed" using the command to take effect. Interface Mapping : The first NIC usually maps to MgmtEth0/0/CPU0 , while subsequent NICs map to GigabitEthernet0/0/0/0 and so on. Segment Routing (SR)
: While 6.1.3 supports basic features, more advanced SR policies and Flex Algo often require newer versions like 6.3.1+ or the IOS XRv 9000. Protocol Testing iosxrvk9demo613qcow2 exclusive
: Ideal for testing BGP Route Reflectors (vRR) and OSPF/IS-IS configurations without physical hardware. Cisco Community CLI commands
for a specific initial configuration, such as setting up the management interface?
QEMU binary: /usr/bin/qemu-system-x86_64
RAM: 4096 MB
Network adapters: 4x virtio-net-pci
Disk image: iosxrvk9demo613qcow2 (exclusive = checked)
Effect: Each instance writes to a copy-on-write overlay, but base image is locked (read-only exclusive). Prevents corruption when multiple labs run concurrently.
This image is almost certainly used in one of these network emulators:
| Platform | exclusive meaning |
|----------|---------------------|
| GNS3 | “Exclusive” flag in QEMU VM settings → prevents snapshot corruption by locking the disk image. |
| EVE-NG | Exclusive mode = image is not shared across labs; each lab gets its own writable copy. |
| Manual QEMU | -drive file=...,locking=exclusive (rare) to force file locking on raw/qcow2. |
