Introduction
- Virtual Machines (VMs) are running on all RP’s and LC’s
- 1x SysAdmin VM and 1x XR VM (Default-SDR) per node
- From the Active XR VM, connect to the SysAdmin VM by typing ‘admin’
- For troubleshooting purposes it is possible to ‘attach’ to remote VM’s
- From SysAdmin VM: attach location x/y
- From XR VM: attach location x/y/cpu0
How does it look on a node
- Sysadmin (also known as Calvados) offers admin plane separation from XR for better fault isolation
- Linux Kernel for scale and performance
- Better manageability – CLI/XML/SNMP/Netconf

State, IOS XR RUN above for RP/LC indicates XR VM is up and IOS XR is running. For FC/FT/PT, the XR VM state is indicated as OPERATIONAL for it to be functional.

HW state (OPERATIONAL) above indicates powered up state and SW state (OPERATIONAL) shows Sysadmin VM to be up and running.
