5.2 Controlling the Host by Modifying
The Xend is a key component of Xen virtualization. It performs management functions
and stores settings that relate to the host environment and each virtual machine. You
can customize Xend to meet your specific configuration requirements.
Important services that must be configured in this file are:
• Settings for live migrations, define migration hosts
• Path to Xend lock files. These can be used to prevent Xen from starting a guest
a second time on a migration host.
• To specify Xend operating parameters, edit the /etc/xen/xend-config.sxp
file. The settings take effect the next time Xend starts.
