GCE (Google Compute Engine) Instance not Receiving DHCP ipv4 address - Support required

Symptom



My new VM instance (Linux Ubuntu - 18.04, created from a working image) does not receive an internal ipv4 address via DHCP (provided by GCE).



Diagnostics / Steps taken so far




  1. Removed virbr0 and recreated virbr0 interface via console access.

  2. Deleted instance and recreated 2x with the same result.

  3. SSH fails due to no ipv4 address.

  4. google shell fails due to no ipv4 address.

  5. console access is accessible.

  6. Tried changing hostname via meta tag and cron job with no luck.


Notes




  1. A working machine created in the same way receives an address and a ens4 interface is created. New machines do not get this.

  2. New builds were created using the cloud console including the license for VMX capabilities.

  3. I wonder if the reason dhcp fails is due to the hostname of the machine not matching the instance name due to the build process. However, the documents i have read indicate, once the ipv4 address is received, the hostname is updated?? Need to verify this.


Any ideas / support would be appreciated.

  • Some Progress - I have now managed to get an ipv4 address by manually running the dhcp client after a boot (it stops once the machine has been restarted). Not sure why it does this when the image it was copied from did not not this but hey ho.

  • What does created from a working image mean? Is this a GCP image or an image from a machine outside GCP?
