The steps to reproduce the bug

Steps to reproduce the issue

  1. Launch a vm in proxmox via cloudstack extension
  2. The vm gets a ip from cloudstack vrouter
  3. Stop the vm
  4. Vr goes into shutdown in Cloudstack
  5. Start the vm frm clodustack

The vm should get a ip address assigned when the vr is rebooted

    can you configure the IP inside the vm, and ping the VR ?

    Is your cluster proxmox only cluster? Cause mine doesn't even build a Vrouter vm, and due to that my proxmox instances dont even get created. Any pointers would be great
