In case you are experiencing a kernel crash ([[oops]]) and have already [[Troubleshooting:Hardwaretesting|checked tested your hardware]], you should report what kernel says to the console (i.e. an [[oops]] text) to [http://bugzilla.openvz.org/ Bugzilla]. Sometimes kernel crashes so badly that <tt>syslogd </tt> is not working and what kernel says it is never written to a file. If this is the case, you have to catch what kernel says. There are several ways possible.
