This is an early technology preview of Virtuozzo 7. We have made some good progress, but this is just the beginning. Much more still needs to be done. In the preview we replaced the containers engine and made our tools work with the new kernel technologies. We consider this beta a major milestone on the road to the official Virtuozzo 7 release and want to share the progress with the community. | This is an early technology preview of Virtuozzo 7.

By balancing and configuring memcg limits we will get the exact overcommit, shadow gangs, swap, page cache overuse Virtuozzo parameters. This will be done by a userspace daemon. | * [[VCMMD|VCMM 4th generation of memory manager]]. We switched to memcg.
