Bug 1450521

+1 - Had another customer see this issue using CloudForms w/ RHEL 7.3 template provisioning to RHV.  Cloud-init version is cloud-init-0.7.9-3.el7.x86_64.  Confirmed that downgrading to 0.7.6 fixed the issue.

The workaround was to hard-code 'hostnamectl set-hostname hostname.mydomain.com' into the runcmd section of cloud-init, because that part appears to run after dbus is started.  This assumes that the cloud-init template will be ONLY used for RHEL7 and is not being used with other flavors of OS that may not use hostnamectl.

also affecting rhel-7.4 latest

here is another workaround: https://bugs.launchpad.net/cloud-init/+bug/1662542

```
# Deactive Default dependencies

sed -i '/^\[Unit\]$/,/^\[/ s/^DefaultDependencies=no/#DefaultDependencies=no/' /usr/lib/systemd/system/cloud-init.service
sed -i '/^\[Unit\]$/,/^\[/ s/^DefaultDependencies=no/#DefaultDependencies=no/' /usr/lib/systemd/system/cloud-init-local.service

# Remove ordering for sysinit.target

sed -i '/^\[Unit\]$/,/^\[/ s/^Before=sysinit.target/#Before=sysinit.target/' /usr/lib/systemd/system/cloud-init.service
sed -i '/^\[Unit\]$/,/^\[/ s/^Before=sysinit.target/#Before=sysinit.target/' /usr/lib/systemd/system/cloud-init-local.service

# order with systemd-hostnamed.service

sed -i '/^\[Unit\]$/,/^\[/ s/^After=networking.service/After=networking.service\nAfter=systemd-hostnamed.service/' /usr/lib/systemd/system/cloud-init.service
```

Red Hat Training is also seeing this issue as we work on the next update of our RHV training course.  We would love to see a fix here before we release the course, otherwise we're going to have to carry information about the regression and the work around in the course.  We also confirm that downgrading from 0.7.9 to 0.7.6 works around the issue.

Hi, Ryan
I've checked with 0.7.9-16test version and it doesn't update hostname

Would it be possible to provide the full output of the boot process?

Created attachment 1353586 [details]
/var/log for cloud-init-0.7.9-16test

Here is the whole /var/log folder
Or you can check this VM on the https://compute-ge-9.scl.lab.tlv.redhat.com/ovirt-engine/webadmin/?locale=en_US#vms
VM name is cloud_init_test

(In reply to Vladimir from comment #26)
> Yes, this one works fine, hostname is set successfully

checked with: cloud-init-0.7.9-18.el7

moving to verify

Guys this is 9 months old.  Seriously?

It's been fixed for months. If you need a package with a fix sooner than the RHEL 7.5 GA, please go through the regular support channels and let them know you need a z-stream.

If you're not a customer, I can post attach the patch here, but there's only so much engineering can do without somebody asking.

fix for the startup ordering

Thanks for clarifying. I don't see the cloud-init-0.7.9-18.el7 release anywhere (apparently as you said it's in EL Z).  This is also a current issue in Fedora 27 and even Rawhide (see below).  Any chance we can include Fedora and Fedora Atomic?

Thanks

Yes I have a subscription and access to Z-Stream repos but surprised it's not GA yet and surprised it's not hit Fedora yet.

Sure, I can work with the Fedora maintainer to get it fixed there. The build mentioned in the comments was an interim build that was only tested internally.

In general, we're only able to release a package with a fix between releases in RHEL if there's an associated customer who asks for a package with a fix sooner, and that request is approved -- it's kind out of our hands.

For Fedora, there's a lot less process involved, and getting a fix out shouldn't take long at all. Could you please file a bug against the Fedora package? You can clone this bug against the Fedora releases that are broken to save time.

OK excellent thanks Ryan.  I'll file that now.

Hi,

I am having the same issue for CentOS 7 VM, any fix for this?

Created attachment 1417331 [details]
patch

Yes, the fix will be in the next release. I have attached the patch that fixes it if you don't want to wait.

I have noticed the RHEV not using the cloud init pay load for CentOS machines VM. We are using the following version 


cloud-init.x86_64                                           0.7.9-9.el7


I will provide an update after I applied the patch. Hopefully this should work.

Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
