I use vzctl compact every night via cron, it is partially help,
but I can't continuously run vzctl compact at HN, and wasted space
inside CT will grow every time during day then container is running
and do something useful.

Why not? zvol is block device - it exported by host as block device
and inside VM this block device /dev/vda formatted as XFS filesystem
and used as any other block device, like /dev/sda on hardware node.
(via creating partitions on it, as it done with any other block device)
But this is most useful only for VMs (Linux,Windows,etc) using KVM.
