Assign /112 IPv6 range to OpenVZ VPS

I have a /48 IPv6 and would like to chop these up into /112's that I can assign to my VPSes.
I know how to assign them manually, e.g.

vzctl set 1 --ipadd ipv6IP --save

But how could I assign, for example, a full /112 at once?

Answer

Use veth. In VE:

/sbin/ip -6 addr add IPv6_ADDR/112 dev eth0
