IP address for VM is not properly determined

[0xff8]

Hi, guys,

After the upgrade to the latest version 2.23.0 of the tart and tart-gitlab-executor 1.21.0-7973405 and pulling latest ubuntu image I am having a problem
The command tart ip shows wrong IP address for a virtual machine and pipelines stopped to work.

Please see the screenshot:

Any clue what might be wrong?

Unfortunately macOS's DHCP server is treating hw_address and identifier fields in /var/db/dhcpd_leases the same way and putting the client identifier, which is a DUID/IAID in your case, into the hw_address field, making it impossible for tart ip to locate the corresponding entry given a MAC-address.

You need to disable DUID/IAID/non-MAC identifiers in your VM to work around that.

See cirruslabs/linux-image-templates#39 for more details.

Thanks @edigaryev for the response. Could it be disabled in the base image then ghcr.io/cirruslabs/ubuntu:latest ? Previous version of that image was working fine..

Test with the macOS image - same problem:

Hmm, indeed. It seems that 99_cirruslabs.cfg didn't make it to the VM for some reason.

Could you please re-pull the image? It should work now.

This is unlikely related. Are you running macOS 15 (Sequoia) on the host by a chance?

If so, please see the top of the Gitlab Tart Executor's README.md explaining this issue.

Yes, I am running macOS 15.2 . I have installed GitLab Runner latest version I have changed the security options for it according the readme.md:

but still machine stuck :/

Using Custom executor...

Hello,

If it is still relevant, to make tart ip <vm> work for ubuntu, it necessary to add dhcp-identifier: "mac" to the /etc/netplan/50-cloud-init.yaml and restart. Example:

network:
  version: 2
  ethernets:
    enp0s1:
      dhcp4: true
      dhcp-identifier: "mac"

tested with ubuntu 24.10
