HAProxy Logging Hostname to Syslog.
By default HAProxy will not log the system hostname to syslog. For me this meant that syslog-ng was inserting “127.0.0.1″ instead of the machine name. I use the machine name to filter my log entries to specific files.
I found an undocumented feature in the latest HAProxy, log-send-hostname which changes this behaviour.

Unnecessary CentOS Services on a VM.
When running CentOS inside a VM, there are a number of services you get that are not needed. I found the following services that I ended up disabling.
service smartd stop && chkconfig smartd off
service avahi-daemon stop && chkconfig avahi-daemon off
service cups stop && chkconfig cups off
service autofs stop && chkconfig autofs off
service iscsid stop && chkconfig iscsid off
service iscsi stop && chkconfig iscsi off
service bluetooth stop && chkconfig bluetooth off
service kudzu stop && chkconfig kudzu off
service mdmonitor stop && chkconfig mdmonitor off
service hidd stop && chkconfig hidd off
service haldaemon stop && chkconfig haldaemon off
service gpm stop && chkconfig gpm off
