This defines 4 LUNs: /dev/mpath/oramp1, /dev/mpath/oramp2, /dev/mpath/oramp3, and
dev/mpath/oramp4. The devices will reside in the /dev/mpath directory. These LUN names are
persistent after reboots as it creates aliased names on the wwid for each of the LUNs.
33.15. Disable SMART disk monit oring for guest s
SMART disk monitoring can be disabled as we are running on virtual disks and the physical storage
is managed by the host.
/sbin/service smartd stop
/sbin/chkconfig --del smartd
33.16. Cleaning up old Xen configurat ion files
Over time you will see a number of files accumulate in /var/lib/xen, the usually named
vmlinuz.****** and initrd.******. These files are the initrd and vmlinuz files from virtual
machines which either failed to boot or failed for some other reason. These files are temporary files
extracted from virtual machine's boot disk during the start up sequence. These files should be
automatically removed after the virtual machine is shut down cleanly. Then you can safely delete old
and stale copies from this directory.
33.17. Configuring a VNC Server
To configure a VNC server use the Remot e Deskt o p application in Syst em > Pref eren ces.
Alternatively, you can run the vino-preferences command.
The following steps set up a dedicated VNC server session:
1. Edit the ~/.vnc/xstartup file to start a GNOME session whenever vncserver is started.
The first time you run the vncserver script it will ask you for a password you want to use for
your VNC session.
2. A sample xstartup file:
#!/bin/sh
# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
#xsetroot -solid grey
#vncconfig -iconic &
#xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
if test -z "$DBUS_SESSION_BUS_ADDRESS" ; then
eval `dbus-launch --sh-syntax –exit-with-session`
