Hi,

1. OK, you want to distinguish your VEs (which is has been updated and which is not yet). But you could simply change VE's name

vzctl set VEID --name YOUR_NAME_UPDATED --save

. Let's assume that we have updated our VPS. We should simply change VE's name (OLD_NAME ---> OLD_NAME_UPDATED).
Why do you use OSTEMPLATE parameter from conf file for these purposes? To my mind you shouldn't do that. And there is some reasons:
a) Some vz* utilities (for example vzyum utility) use OSTEMPLATE value from VE's conf file. So if it will not be able to parse OSTEMPLATE parameter you will not be able to use this utility. You must keep it in mind.
b) from OpenVZ user's guide "You do not have to change this parameter" Smile

2. Why do you want to update guest's kernel?
3.

Quote:

Is it possible to update a guest without changing the host?

You can update guests like common operating systems (via yum, vzyum etc). But you cannot update kernel, you can only install appropriate package, but you will not be able to boot in it. HN and VE use the same OVZ kernel. BUT! any software inside VE might be considered like the software on the separate system.

P.S.
save your data before upgrading your guests.
Some wiki pages are describing the update process. For example
