amitmvyas opened a new issue, #13006: URL: https://github.com/apache/cloudstack/issues/13006
Hi, I have downloaded Ubuntu 22.04 Image (CKS) from [here](https://download.cloudstack.org/testing/custom_templates/ubuntu/22.04/cks-ubuntu-2204-kvm.qcow2.bz2). When deploying the CKS cluster using this image I am seeing that Calico POD on Master and Worker node is failing because of /etc/hosts file don't have anything configured in it. ```

I haven't seen this happening when deploying CKS using system template. Has any once faced such issue ? Regards, Amit Vyas -- This is an automated message from the Apache Git Service.
