● Before you begin to create a XenVM, the required resources should be available. The
system requirements depend on the operating system which is to be installed. You must
in particular ensure that a virtual disk of a sufficient size exists or can be created so that
the guest system can be installed without any problem. The Data Center Edition of
Windows 2008 Server requires, for example, at least 18 GB of disk storage. Before
creation begins, missing resources must be configured to offer sufficient capacity, e.g.
create or extend disk pool (see section “Managing virtual disks” on page 191), upload
ISO image of the required operating system to the local library as an installation source
(see section “Managing installation sources” on page 195).
Ê Click Create new XenVM.
In the Create new XenVM wizard you can specify the required properties of the XenVM
step by step.
The wizard initiates the process of VM creation in the background and, depending on
the installation type, also installation and startup of the XenVM.
Monitoring configuration of the XenVM and error handling
When a XenVM is configured, all the resources specified in the wizard must be available at
this time.
If the configured XenVM is started immediately, configuration of a XenVM is a process
which can take somewhat longer depending on the resources specified (in particular main
memory).
As a complete check to ensure that all the configuration data is correct and consistent only
takes place in the course of this process, an error (e.g. incorrect installation source) results
in the process aborting relatively quickly (aborted status on the VM installation tab), and no
XenVM is configured. In this case the error message and error cause can be displayed
directly in the dialog window.
However, it can occur that the configuration process starts normally (e.g. reaches the
INSTALL status in the case of installation), but the configured XenVM is subsequently
discarded (e.g. because of a memory bottleneck). In this case you will find no XenVM in the
dialog window despite the supposed positive acknowledgment. If the XenVM is displayed
in the navigation, you will also find the current status in the XenVM-specific Operation tab.
If the installation or configuration process has not reached one of the statuses ABORTED,
INSTALL or FINISHED after a certain time, the monitoring function of the process is aborted
with a corresponding message. You will find the current status in the logging file of the
installation or configuration process (see the VM installation tab). If the XenVM is displayed
in the navigation, you will also find the current status on the XenVM-specific Operation tab.
