Are there any docs about this sysctl? I've googled and searched the
openvz wiki and all I found is the announcement that it has been added
some time in 2008 with no further explanations.

One would think that it should be pretty straightfoward; 0=off, 1=on,
but on all my systems it is set to 2 which makes me wonder if there is
more to it.
