Depends.
There are two branches based on 2.6.32... the generic one and the RHEL6-based one. Both are still marked as "Development" here:
http://wiki.openvz.org/Download/kernel
There is also a 2.6.32-based kernel that Debian has in their repos for Debian 6. I believe it uses the OpenVZ 2.6.32 generic patch but of course Debian's kernel isn't the stock kernel.org kernel.
I've heard of a few differences in functionality between the RHEL6-based kernel and that shipped by Debian. Ubuntu does not offer an OpenVZ kernel that I'm aware of.
I've been using the RHEL6-based kernel on RHEL 6.1 and it seems to work fine but it isn't a production machine and I haven't done a whole lot of testing. The OpenVZ Project has been updating the RHEL6-based kernel frequently both to keep up with RHEL kernel updates as well as fix OpenVZ-related bugs that are reported.
So, what host node distro are you planning on using? I'd recommend using the RHEL6-based OpenVZ kernel if at all possible. If you haven't done so already, I strongly recommend you setup a system and give it a try for yourself... and do some testing. If you find any bugs report them to bugzilla.openvz.org.
TYL,
