You have been subscribed to a public bug: On Azure, cloud-init relies on the system-uuid as based by SMBIOS a unique ID for a cloud instance. If this ID ever changes, then cloud- init will attempt to reprovision the VM.
This recent kernel patch in the Ubuntu kernel corrects the endianness for some SMBIOS fields, but also has the effect causing cloud-init to think that the system-uuid has changed: http://kernel.ubuntu.com/git/ubuntu/ubuntu- trusty.git/commit/drivers/firmware?id=3ec24c55be6c543797ba3ee9a227a5631aef607e The impact is that cloud-init attempts to reprovision the VM, often causing the customer to lose access to their VM. ** Affects: linux (Ubuntu) Importance: Critical Assignee: Dan Watkins (daniel-thewatkins) Status: Confirmed ** Tags: kernel-da-key -- Fix UUID endianness patch breaks cloud-init on Azure https://bugs.launchpad.net/bugs/1551419 You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
