So in addition to a kernel fix, we will first need to release a cloud- init that will handle the endian-ness of instance IDs changing underneath it.
This is because the kernel is already out in the wild, so we will have some instances that have booted with the new UUID and the kernel fix will also trigger the behaviour seen in this bug. ** Also affects: cloud-init (Ubuntu) Importance: Undecided Status: New ** Changed in: cloud-init (Ubuntu) Assignee: (unassigned) => Dan Watkins (daniel-thewatkins) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1551419 Title: Fix UUID endianness patch breaks cloud-init on Azure Status in cloud-init package in Ubuntu: New Status in linux package in Ubuntu: Confirmed Bug description: 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.
