It's not a bug, but I understand from your perspective that it appears to be one. We introduced ds-identify to prevent cloud-images from attempting to connect out to URLs when none are available. Cloud-init was slower since it needed to attempt to see if any network-based datasources were present and this also prevents cloud-init from responding to network sources when it should not. Cloud-init would also run even if no datasources or user-config were provided at all which meant running a cloud-image outside of a cloud would hang for a very long time waiting for cloud-init to timeout. > > Also, if I modify the official cloud image and disable any datasource > *except* Ec2 (i.e., write `datasource_list: [ Ec2 ]` into > `/etc/cloud/cloud.cfg.d/90_dpkg.cfg`), then everything works fine. > > So the issue is really `ds-identify` being too picky about when the > `Ec2` datasource is valid; from a cursory look, I can see that it just > checks if `/sys/hypervisor` contains some well-known AWS tag -- but > there are many cloud services which provide EC2-compatible metadata > (OpenNebula being another example), which would be skipped by this > logic! The ds-identify checks use local information on the instance to check if it is running on a cloud platform. For OpenStack, the method used is to set DMI values to indicate the VM is running on OpenStack. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1855458 Title: cloud-init on Ubuntu 18.04 image does not run in VIO To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cloud-init/+bug/1855458/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
