** Description changed: + === Begin SRU Template === + [Impact] + Ubuntu cloud-images do not identify the Aliyun cloud platform. + Until this change was put in place, they would fail to boot and consume + user-data or metadata there. + + With the change in place, an official Ubuntu image from + http://cloud-images.ubuntu.com will work properly on Aliyun. + + [Test Case] + The ideal test case is: + a.) download a cloud image, update its cloud-init + The tool 'get-proposed-cloudimg' [1] can be used to do this. + + [1] https://git.launchpad.net/~smoser/cloud-init/+git/sru- + info/tree/bin/get-proposed-cloudimg + + b.) publish that image to Aliyun cloud + c.) boot an instance from that image. + d.) verify function by ssh in verifying /run/cloud-init/result.json shows + that aliyun datasource was used. + + Ideally post /var/log/cloud-init.log as an attachment to this bug. + + [Regression Potential] + Generally small chance for regression, but a regression would most likely + be seen as an attempt to hit the metadata service at the well known end point + http://100.100.100.200. + + This should be fairly well confined as attempts to use the Aliyun datasource + are gated by '_is_aliyun_' which does verifies that the dmi product name is + "Alibaba Cloud ECS" + + [Other Info] + Upstream commit at + https://git.launchpad.net/cloud-init/commit/?id=4a60af5495 + + === End SRU Template === + + As discussed at [1], the addition of AliYun datasource did not enable it by default. This is because it has no definitive check before polling the network for data. Lawrence suggested he has a solution for this: - | in our cloud platform, an instance vm could use an asm - | instructions `cpuid` (with eax setted to 0x40000100 ), it will - | returned our platform id keyword "AliYun" into register ebx and ecx, - | and if vm is not running on our environment, the value is others. so I - | guess this is a method to identify our platform ? + | in our cloud platform, an instance vm could use an asm + | instructions `cpuid` (with eax setted to 0x40000100 ), it will + | returned our platform id keyword "AliYun" into register ebx and ecx, + | and if vm is not running on our environment, the value is others. so I + | guess this is a method to identify our platform ? -- [1] https://code.launchpad.net/~smoser/cloud-init/+git/cloud-init/+merge/309614
