Amazon Web Services has silently edited your frequently asked questions, revealing that you have created a new KVM-based hypervisor and will use it instead of Xen for future instances.
The web page contains no mention of the hypervisor. But saving the page in Google's cache does. And in case AWS cleans it, we take this screenshot and screenshot of the now modified page.
If you can still see references to the new KVM-based hypervisor in Amazon dotcoms, then you will see a cached copy: the information disappears. The Internet Archive took a snapshot of the site on Wednesday and could not find a word on KVM development. From computers in California, Australia, and Europe, we can only see the version of frequently asked questions that has been removed from the new custom hypervisor. And our contacts in the industry have also seen the change.
Amazon's announcement of its new C5 instances still mentions a new hypervisor. We covered this screen, here too, and here, in case AWS would put it in the hole of memory.
Why did Amazon do that? The company is already marked and wants to talk about its hypervisor later this month at its conference re: Invent. We suspect that this does not mean that the hypervisor information was made public before that date. With luck, all concerned have maintained their work.
And now, a confession: the recording hackers were very excited when we discovered the new hypervisor, and we missed one or two details that we have now noticed by rereading the frequently asked questions. For starters, it seems like the new hypervisor is about server support with NVMe. Running virtual machines will boot from EBS volumes using an NVMe interface, instead of the emulated IDE device used in the AWS Xen implementation.
More proof that they are flashy servers: AWS also states that "most applications will work the same way with Xen and the new EC2 hypervisor, provided that the operating system has the necessary support for the networks ENA and NVMe storage. "
Speaking of Xen, he is not completely out of the immediate plans of AWS, because the company says that "in the short term, certain types of new instances will use Xen according to the requirements of the platform."
But the long-term prospects for the hypervisor are bad because AWS says that "all new instance types will use the new EC2 hypervisor."
We asked AWS to explain its hypervisor strategy and the Linux Foundation, which oversees the Xen project, to comment on the loss of its most important user. If any of you respond, we will inform you of your offers. ®
