We are pleased to announce the official release of [[Virtuozzo 7.0 Beta 1. This ]] is our first public releasea Linux distribution based on opensource OpenVZ components.
More than ten years ago we released This is an early technology preview of Virtuozzo containers7. We have made some good progress, but this is just the beginning. At that moment Linux kernel lacked isolation technologies and we had Much more still needs to implement it as a custom kernel patchbe done. Since then In the preview we worked closely replaced the containers engine and made our tools work with the community to bring these new kernel technologies to upstream. Today it is part of most modern Linux kernels and there is no value in continue using proprietary technologies. So we made We consider this beta adecision major milestone on the road to switch the official Virtuozzo 7 release and want to upstream technologies as a strong foundation for share the progress with the future of our productcommunity.
This is an early technology preview for == Key Changes == * Virtuozzo 7is based on RHEL7 and [[Download/kernel/rhel7-testing|Kernel 3. We have made some good progress10+]]* Containers are using kernel features cgroups and namespaces that limit, account for, but this is just and isolate resource usage as isolated namespaces of a beginningcollection of processes. We still have The beancounters interface remains in place for backward compatibility. At the same time it acts as a lot more to be doneproxy for actual cgroups and namespaces implementation. At this point * UUID instead of time you won't see new cool featuresVEID for container identification. You can use UUID or name to identify a container. We replaced an engine for containers and made our tools work with By default vzctl will treat the new kernel technologiesformer VEID parameter as name.* [[VCMMD|VCMM 4th generation of memory manager]]. We consider this delivery as major milestone on the road switched to official Virtuozzo 7 release memcg. By balancing and want to share configuring memcg limits we will get the progress with our customersexact overcommit, shadow gangs, swap, page cache overuse Virtuozzo parameters. In the future we'll This will be sharing our development progress continuously. The next step is introducing new virtual machines based on KVM. And then more features are comingdone by a userspace daemon.
