5.7 Virtual Machine Initial Startup

Files

During the process of creating a new virtual machine, initial startup settings are written

to a le created at /etc/xen/vm/. During the creation process, the virtual machine

starts according to settings in this le, but the settings are then transferred and stored

in xend for ongoing operations.

IMPORTANT

Modifying the initial startup le 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 Section 4.3, “Cong-

uring a Virtual Machine by Modifying its xend Settings” (page 30) or to follow

the instructions in Section 5.4, “The Boot Loader Program” (page 42).

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 le.

Although it is not recommended, you might need to start an existing virtual machine

based on settings in the initial startup le. If you do this, any xend settings stored for

the virtual machine are overwritten by the startup le settings. Initial startup les are

saved to /etc/xen/vm/vm_name. Values must be enclosed in single quotes, such

as localtime = '0'.
