[Users] SSD trim support over a LUKS layer

[spameden]

No. It's impossible to use OpenVZ 6 with kernel 4.x, unless you put lots of
effort to port their patches over the fresh kernel.

The latest OpenVZ 6 kernel is 2.6.32-openvz-042stab136.1-amd64 and there is
an issue with discard (it doesn't work).

The discard issue has been fixed in 3.1-mainline kernel I think, you can
look over newish RHEL kernel and try to port those changes to the old
legacy OpenVZ 6 kernel.

Regarding 4.x kernel:
I'm using Proxmox with 4.x kernel (there is no OpenVZ) - only LXC
containers and KVM - and there is no issue with discards at all.
and what I also meant is: that you can easily migrate your existing OpenVZ
containers to the Proxmox.

Proxmox is based on latest Debian Stretch and specifically designed as a
distro for contrainers.
It has GUI, networking support (including openvswitch and other), KVM/LXC
support and many other things (e.g. ceph/glusterfs support).

Though, reading you again you've mentioned that you need a specific simfs
quota in containers:
most likely that would be impossible for unprivileged containers with
directory storage (simfs analogue), althrough you could use qcow2 or
LVM-based storage for containers.
