@adriangabura said in XCP-ng 8.1.0 beta now available!:

Thanks for the update! I've installed the update on one of my servers, it works. If it will work fine I'll try on another server.

Are there some technical issues that would explain why Dynamic Memory Control was deprecated by Citrix?

There was some talk about in https://xcp-ng.org/forum/topic/2254/citrix-hypervisor-8-1-released/23 .
Personally I am happy to see DMC go. I've not used it for years now after VMs sometimes crashed due to running out of memory. At that time the ballooning would happen during every live migration if I remember correctly, even though there was plenty of RAM available.

@cg You should be careful when recommending dedup on ZFS. I think (but my knowledge might be outdated) there are still at least some caveats people should be aware of.
A quick search reveals you typically need 1-5 GB of RAM per TB of storage.
