================================================================

manual workaround: (after each container reboot)

[root@hardware-node]# vzctl enter 108
entered into CT 108
[root@container-108]# ip addr add 172.22.22.108 dev venet0

we need better workaround or complete solution of this regression

A better workaround is to apply this patch:
