18.3. 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/
