Yeah, we were discussing this.  It has already been fixed in the dev version of vzctl but it hasn't been pushed to a release yet.

For more info, see: https://bugzilla.openvz.org/show_bug.cgi?id=3169

In the mean time, you can fix it yourself by editing the /etc/dists/scripts/redhat-add_ip.sh file and adding the line:

ARPCHECK=\"no\"

You have to add it twice as seen here:

I noticed it with the Fedora 21 beta OS Template... and then when I upgraded my contributed Oracle 7.1 OS Template.  I guess CentOS 7.1 just came out? :)
