NOTE: CentOS Enterprise Linux 5 is built from the Red Hat Enterprise Linux source code. Other than logo and name changes CentOS Enterprise Linux 5 is compatible with the equivalent Red Hat version. This document applies equally to both Red Hat and CentOS Enterprise Linux 5.

19.3. Important Directory Locations

There are additional utilities and logfiles you should remember when you track errors and troubleshoot problems within Red Hat Virtualization environments:

  • Virtual machines images reside in the /var/lib/xen/images directory.

  • When you restart the xend daemon, it updates the xend-database that resides in the /var/lib/xen/xend-db directory.

  • Virtual machine dumps (that you perform with xm dump-core command) resides in the /var/lib/xen/dumps directory.

  • The /etc/xen directory contains the configuration files that you use to manage system resources. The xend daemon configuration file is called xend-config.sxp, and you can use this file to implement system-wide changes and configure the networking callouts.

  • The proc commands are another resource that allows you to gather system information. These proc entries reside in the /proc/xen directory:

/proc/xen/capabilities

/proc/xen/balloon

/proc/xen/xenbus/
