@olivierlambert is this something that can be turned in as an issue to an open source enforcement group of some kind? Any recommendations of one to ask?
Thanks

@olivierlambert very interesting. I'll bet we never see this, such a shame. They have an open source release center here:
https://consumer.huawei.com/en/opensource/
however the link to cloud goes to not found.
I'll try some emails, and see if I can get anywhere. The developer who did the presentation never responded to the email address posted in the presentation.

@olivierlambert If Huawei developers implemented this feature in Huawei Cloud as an open source derivative, would they not be required to provide their source code back to the upstream project?

@olivierlambert strictly a density thing. it's a main vmware feature, and one of the things other virtualization environments lack. I got excited seeing huawei has actually worked on it, then couldn't find any other references to it other than that presentation.

We've recently decided to give Xen another shot, and love the direction of the XCP-ng project.
I've been searching various xen sites and sources for memory overcommitment, since that's a feature we need.
I came across a presentation by Huawei in 2018, showing some impressive usage and stats on this topic:

I'm wondering if any of this has made it back to Xen sources, or if it is still a Huawei only feature.
