Hi team,
I have a mysql running in AWS EC2. I followed all the steps and setup mentioned in the Istio / Virtual Machine Installation but am always getting this error while starting the istio via sudo systemctl start istio in the vm am getting this error.

It looks like the dns is not able to resolve istiod.istio-system.svc. Depending on your cluster setup, you will have to provide the ip address so that it can reach istiod. I hope this helps. Without understanding your cluster setup, it is difficult to provide more details. A few things u can try is to add the ip address to your /etc/hosts file so that it can reach istiod. Another is to make an entry in route53 so that it can resolve the host name.
