6.6 Virtual Machine Initial Startup
During the process of creating a new virtual machine, initial startup settings are written
to a file created at /etc/xen/vm/. During the creation process, the virtual machine
starts according to settings in this file, but the settings are then transferred and stored
in xend for ongoing operations.
IMPORTANT
Modifying the initial startup file to create or make changes to a virtual machine
is not recommended. The preferred method for changing a virtual machine's
settings is to use Virtual Machine Manager as described in
uring a Virtual Machine by Modifying its xend Settings"
the instructions in
When a virtual machine's settings are stored in xend, it is referred to as a
xen-managed domain or xen-managed virtual machine. Whenever the
xen-managed virtual machine starts, it takes its settings from information stored in the
xend database, not from settings in the initial startup file.
Although it is not recommended, you might need to start an existing virtual machine
based on settings in the initial startup file. If you do this, any xend settings stored for
the virtual machine are overwritten by the startup file settings. Initial startup files are
saved to /etc/xen/vm/vm_name. Values must be enclosed in single quotes, such
as localtime = '0'.
