Feature Support: While it mimics the CLI and OS behavior, certain hardware-dependent features (like specific QoS or advanced ASIC-based functions) may not be fully functional. Installation Requirements The file iosxrv-k9-demo-5
The iosxrv-k9-demo-5.2.2.ova is a virtual machine image package provided by Cisco Systems. It contains a version of the Cisco IOS XRv 9000 router, which is the virtualized incarnation of Cisco's carrier-grade operating system, IOS XR. This specific "demo" image is intended for lab environments, testing, training, and feature evaluation. It allows network engineers to simulate high-end router behavior (such as the ASR 9000 series) on standard x86 hardware without requiring physical chassis hardware. Operating System : Cisco IOS XR (64-bit, Linux-based)
iosxrv-k9-demo-5.2.2.ova — Overview and Practical Guide
Introduction iosxrv-k9-demo-5.2.2.ova is a virtual appliance image of Cisco IOS XRv — a virtualized version of Cisco’s IOS XR network operating system — packaged as an Open Virtual Appliance (OVA). It’s intended for lab, testing, learning, and development use: providing router functionality, IOS XR feature behavior, and a realistic platform for experimenting with service-provider routing technologies without requiring physical Cisco hardware.

- Cause: IOS XR 5.2.2 uses older crypto algorithms (e.g.,
diffie-hellman-group-exchange-sha1) disabled by modern SSH clients. - Fix: In your SSH config (
~/.ssh/config), add:
Or use a legacy SSH client.Host xrv-demo KexAlgorithms +diffie-hellman-group-exchange-sha1 HostKeyAlgorithms +ssh-rsa
Power On
The console will show GRUB boot (IOS XR). First boot takes 3–5 minutes.
