I had to create the following dummy "template":
# tree /vz/template/gentoo/22
/vz/template/gentoo/22
└── x86_64
    └── config
        └── os
            └── default
                ├── description
                ├── distribution
                ├── mirrorlist
                ├── no_pkg_actions
                ├── package_manager
                ├── packages
                └── summary

4 directories, 7 files
#

and use

OSTEMPLATE="gentoo-22-x86_64"

in the ve.conf file.

"22" is just a random number, without it vzctl weren't able to
pick up network script(s) .

 'description' an 'summary' files have the same content:

# cat /vz/template/gentoo/22/x86_64/config/os/default/description 
gentoo 22 (for x86_64) OpenVZ template

'distrubution' file:
# cat /vz/template/gentoo/22/x86_64/config/os/default/distribution 
gentoo

the remaining four files are empty.
