Title: [SRU] CloudSigma DS for causes hangs when serial console present Status in Init scripts for use on cloud images: Fix Committed Status in Openstack disk image builder: Fix Released Status in tripleo - openstack on openstack: Invalid Status in “cloud-init” package in Ubuntu: Fix Released Status in “cloud-init” source package in Trusty: Fix Released Bug description: SRU Justification Impact: The Cloud Sigma Datasource read and writes to /dev/ttyS1 if present; the Datasource does not have a time out. On non-CloudSigma Clouds or systems w/ /dev/ttyS1, Cloud-init will block pending a response, which may never come. Further, it is dangerous for a default datasource to write blindly on a serial console as other control plane software and Clouds use /dev/ttyS1 for communication. Fix: The patch queries the BIOS to see if the instance is running on CloudSigma before querying /dev/ttys1. Verification: On both a CloudSigma instance and non-CloudSigma instance with /dev/ttys1: 1. Install new cloud-init 2. Purge existing cloud-init data (rm -rf /var/lib/cloud) 3. Run "cloud-init --debug init" 4. Confirm that CloudSigma provisioned while CloudSigma datasource skipped non-CloudSigma instance Regression: The risk is low, as this change further restrict where the CloudSigma Datasource can run.
