Hi @stgraber, thank you for your continued developement of this project!
I buy large KVM VPS and want to (mis)use linux containers to limit one client to a certain amount of resources, like CPUs and Memory. It is possible to reformat the VPS through a rescue system but the underlaying storage system seems to become slow when trying to run ZFS or btrfs so I have to stick with ext4. Also reformatting takes a huge amount of time and sometimes scrambles the virtual disks so one partition all ext4 is what I have to use.
Is there a way to run LXCs on ext4 directories without them slowing down?
Are project quotas introduced in kernel 4.4 leveraged for storage limitations?
Or am I misunderstanding this and only the copy-on-write features will be very slow but the container itself will be as fast as on the VM itself?
