(1) As far as I remember, ssh and httpd are on by default in opensuse
template.
(2) To enable services from the command like, you can use
/sbin/chkconfig utility.
Examples:
/sbin/chkconfig --list
will give you a list of all services and their settings on different
runlevels
/sbin/chkconfig --level 345 sshd on
will enable sshd for runlevels 3, 4, and 5
/sbin/chkconfig --list sshd
will show you the settings for sshd
Finally, if you want, say, sshd to start without reboot, run
/etc/init.d/sshd start

The other problem that can happen with opensuse template is UBC
shortage. Take a look at http://wiki.openvz.org/Resource_shortage.
Basically, you need to check /proc/user_beancounters inside a VE and if
the last column contains non-zero numbers, do something about it (see
the wiki article referenced above).
Finally, I will be updating opensuse template really soon (this week I
hope), and will post a detailed HOWTO on how you can create your own
opensuse template with all the software and settings you want to have.
