The New VM wizard takes you through the process of creating a new virtual machine (VM), step-by-step. To start the New VM wizard, on the toolbar, click New VM.
Alternatively, do one of the following:
Press Ctrl+N . On the VM menu, click New VM. Select a server in the Resources pane, right-click and then click New VM on the shortcut menu. Using the wizard, you can configure the new VM exactly the way you want it, adjusting various configuration parameters for CPU, storage and networking resources.
VMs can be imported from OVF/OVA packages, from disk images, and from XenServer XVA files. VMs can be exported as OVF/OVA packages and as XenServer XVA files. You import and export VMs in XenCenter using the Import and Export wizards. XenCenter uses the Transfer VM to transfer the content of a disk image.
When importing VMs created on hypervisors other than XenCenter, for example Hyper-V or VMware, it is necessary to use the Operating System Fixup tool to ensure that imported VMs can boot on XenServer.
Citrix XenServer is a complete, managed server virtualization platform built on the powerful Xen hypervisor. Xen technology is widely acknowledged as the fastest and most secure virtualization software in the industry. XenServer is designed for efficient management of Windows® and Linux® virtual servers and delivers cost-effective server consolidation and business continuity.
What is server virtualization? Server virtualization is a proven technology that enables multiple virtual machines to run on a single physical server.
Using XenCenter, a storage repository can be removed temporarily or permanently:
Detach. Detaching a storage repository breaks the association between the storage device and the pool or server, and its virtual disks become inaccessible. The contents of the virtual disks and the meta-information used by virtual machines to access the virtual disks are preserved. Detach can be used when you need to temporarily take a storage repository offline, for example, for maintenance.
Resource Pool: Combining one or more xenservers as a single unit is resource pool
Resource pool member host types
master pool member
single control point for all XS in the pool maintains pool configuration data manages distributed locking for shared storage configures seconday xs in the pool Secondary pool member
controlled through the master maintains pool configuration backup can be promoted to pool master Citrix XenServer pools allow you to view multiple servers and their connected shared storage as a single unified resource, enabling flexible deployment of virtual machines based on their resource needs and business priorities.
A XenServer vApp is a logical group of one or more related virtual machines (VMs) which can be managed as a single entity. The VMs within a vApp do not have to reside on one host server and will be distributed within a pool using the normal rules.
When a vApp is started, the VMs contained within it will start in a user-defined order, allowing VMs which depend upon one another to be automatically sequenced.

Here is a good pdf document from citrix which shows complete step by step explanation about how to install and configure XenServer License Virtual Appliance.
A collection of virtual hardware that creates a standard x86 or x64 enviornment that allows for the installation of a supported guest operating system.
A virtual machine is a software computer that, like a physical computer, runs an operating system and applications. The virtual machine is comprised of a set of specification and configuration files and is backed by the physical resources of a host. Every virtual machine has virtual devices that provide the same functionality as physical hardware and have additional benefits in terms of portability, manageability, and security.
A LAN is a local area network and is defined as all devices in the same broadcast domain. If you remember, routers stop broadcasts, switches just forward them.
What is a VLAN? vlan is a logical configuration of a network on switch port to segment IP traffic. Using vLans reduce h/w needs by allowing a switch to segment IP traffic into multiple IP subnets on a port by port configuration.
Are you a small business owner who wants to expand but dreads the costs of new hardware? Or do you work for a larger company, where the server room has become an expensive hot mess that everybody avoids like the plague? Server virtualization can help you. More and more companies, large and small, realize what significant benefits come from server virtualization. Why? Well simply put, server virtualization enables intelligent usage of IT resources.
