35.4. Important directory locations

There are other utilities and log files you should be aware of for tracking errors and troubleshooting problems with Xen:
  • Guest images reside in the /var/lib/libvirt/images directory by default.
  • 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 the 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 /etc/xen/xend-config.sxp. This file can be edited to implement system-wide changes and configure the networking. However, manually editing files in the /etc/xen/ folder is not advised.
  • The proc folders 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/
