Host provisioning with Google Compute plugin

tania · August 3, 2026, 11:38am

Hi Foreman,

I am having issues creating a new host in foreman using GCP. When I attempt to create a host I see:

Failed to create a compute gcp__bel (europe-west1-b-Google) instance ERF50-1985 [Foreman::WrappedException]: Cannot insert instance! ([Google::InvalidArgumentError]: An error has occurred when making a REST request: Invalid value for field ‘resource.networkInterfaces[0].subnetwork’: ‘’. Network interface must specify a subnet if the network resource is in custom subnet mode.)

In Compute profiles I added the correct VPC under Network, but there is no option to add a subnet. I did add the subnets in the Infrastructure → subnet section, but that does not change the error.
I also attempted to add via hammer or the API but saw the same error message. Even if I tried adding the keywords subnetwork with my subenet name that exists in GCP.

I am running foreman version 3.19.1 with foreman_google plugin 3.0.7

Does anyone have any ideas how I might resolve this?

Many Thanks,

Tania

Hi, this looks like an issue. Could you please share the DEBUG logs from your instance so I can take a look at what’s going on?

Hi,

thanks,
could you also share details about the subnet, host group and compute profile?
You can use hammer for the ouputs, it will show enough data for me.
Feel free to omit sensitive data, I just want to make sure I have same data setup as you.

tania · August 4, 2026, 11:08am

Hi,

I added in Create Host:

Host

Organisation: my_org

Location: GCP_BEL

Host_group: virtual_desktop

Deploy On: gcp_myproject_bel

compute_profile: vdk_staff

environment: master

Puppet proxy: my_proxy

Puppet ca proxy: my_proxy

Realm: MY_DOMAIN

Virtual_Machine

Machine type: n2-standard-4

Network: my_vpc

Size: 40

Operating System

Architecture: x86_64

Operating system: Ubuntu 24.04 LTS (cloud)

Image: Ubuntu-2404-Noble

Provisioning template: finish

Interfaces

ipv4 subnet: gcp_my_subnet

Everything else as is.

Thanks,
Tania

Hi, I drafted a PR for subnet support.
Could you test it in your non-production environment?

With the Packit tool, it should be simple:

sudo dnf install -y 'dnf*-command(copr)'
sudo dnf copr enable packit/theforeman-foreman_google-95 rhel-9-x86_64
sudo dnf install -y rubygem-foreman_google-3.0.8-2.20260805102823619769.pr95.7.g5786832.el9.noarch

Once you confirm it’s working for your case, I will continue with the PR (team reviews, documentation, testing, …)

tania · August 6, 2026, 9:20am

Hi,

I followed those instructions, ran foreman-maintain service restart, confirmed I could see the foreman_goolgle plugin was 3.0.8 in the GUI.

Just navigating to Infrastructure → Compute Resources → clicking on MY_GCP_Resource sees Oops, we’re sorry but something went wrong undefined method ‘name‘ for nil:NilClass.

production.log shows:

Yeah, I think I know where the problem lies, I forgot about the data migration.
Could you try to edit the compute profile and select a subnet (again) and save the profile? That should help.

(I will update the PR to make sure this is handled meanwhile)

lstejska · August 6, 2026, 12:37pm

Fixed it; the new build should be available here: Packit Service

Hi,

Editing it produces the same error message, so can’t edit.

I installed the new build 3.0.8-2 and same error.

I can however edit and see subnets in compute profiles, and creating VM works with the selected subnet.

Thanks,
Tania

Awesome, glad to hear that. I will pass this information to the team and will continue with the issue

Editing it produces the same error message, so can’t edit

Hmm, that means our test coverage is lacking some scenarios , that has to be improved.
