Chapter 19. Red Hat Virtualization Troubleshooting
This section covers potential issues you may experience in the installation, management, and general day-to-day operations of your Red Hat Virtualization system(s). This troubleshooting section covers the error messages, log file locations, system tools, and general approaches to research data and analyze problems.
When deploying Red Hat Enterprise Linux 5.0 with Virtualization into your network infrastructure, the host's Virtualization software uses many specific directories for important configuragtion, log files, and other utilities. All the Red Hat Virtualization logs files are standard ASCII files, and easily accessable with any ASCII based editor:
The Red Hat Virtualization main configuration directory is /etc/xen/. This directory contains the xend daemon and other virtual machine configuration files. The networking script files reside here as well (in the /scripts subdirectory).
All of actual log files themselves that you will consult for troubleshooting purposes reside in the /var/log/xen directory.
You should also know that the default directory for all virtual machine file-based disk images reside in the /var/lib/xen directory.
Red Hat Virtualization information for the /proc file system reside in the /proc/xen/ directory.
