You might be getting this error “A required disk image was missing” while deploying a new virtual machine from CSR 1000v OVA file. You can ignore this error, but the router will not boot after you power it on. I have written below how I managed to deploy CSR 1000v using OVA file and run the VM. I’m not sure if this is the best solution, but it worked for me.
Step 1: Extract the OVA archive
The first thing you need to do is extract OVA archive and locate the ISO file. In my case it was named csr1000v-universalk9.16.08.01a-vga.iso. It is almost of the same size as the OVA archive itself.
Step 2: Upload the ISO file to the datastore
Upload the extracted ISO file to the datastore of your ESXi host.
Step 3: Assign ISO file to VM’s CD/DVD drive
Now you need to Edit Settings of your CSR 1000v VM. Make sure its CD/DVD drive is to your ISO image, like shown on the picture below:
Step 4: Run VM and access its console.
Now you can run your CSR 1000v VM and access its console. The output of the console is similar to that of a regular router’s serial port:
Thank you for reading. Hope this workaround helped you 🙂
