Chapter 3

Starting Additional Domains

The ﬁrst step in creating a new domain is to prepare a root ﬁlesystem for it to boot off.

Typically, this might be stored in a normal partition, an LVM or other volume manager

partition, a disk ﬁle or on an NFS server. A simple way to do this is simply to boot

from your standard OS install CD and install the distribution into another partition on

your hard drive.

To start the xend control daemon, type

# xend start

If you wish the daemon to start automatically, see the instructions in Section 6.1. Once

the daemon is running, you can use the xm tool to monitor and maintain the domains

running on your system. This chapter provides only a brief tutorial: we provide full

details of the xm tool in the next chapter.

3.1 Creating a Domain Conﬁguration File

Before you can start an additional domain, you must create a conﬁguration ﬁle. We

provide two example ﬁles which you can use as a starting point:

• /etc/xen/xmexample1 is a simple template conﬁguration ﬁle for describing

a single VM.

• /etc/xen/xmexample2 ﬁle is a template description that is intended to be

reused for multiple virtual machines. Setting the value of the vmid variable on

the xm command line ﬁlls in parts of this template.

Copy one of these ﬁles and edit it as appropriate. Typical values you may wish to edit

include:

kernel Set this to the path of the kernel you compiled for use with Xen

(e.g. kernel = ’/boot/vmlinuz-2.6-xenU’)
