Rebooting the Cisco CSR 1000v
Once you have copied the new system image into bootflash memory, loaded the new system image and saved
a backup copy of the new system image and configuration, you need to reboot the VM. See your VM vendor
documentation for more information about rebooting the VM. After rebooting, the Cisco CSR 1000v VM
should include the new system image with a newly installed Cisco IOS XE software version.
