Citrix* XenServer* 5.5.0 Installation Guide -
Intel® Server Board S3420GP

System Requirements
XenServer* requires at least two separate physical x86 computers:
One to be the XenServer* host.
One to run the XenCenter* application.
The XenServer host machine is dedicated to the task of hosting VMs and is not used for other
applications. The computer that runs XenCenter can be any general-purpose Windows* computer with
the hardware requirements, and can be used to run other applications simultaneously.
XenServer* Host System Requirements
The XenServer* host is a 64-bit, x86 server-class machine devoted to hosting multiple VMs. This
machine runs a stripped-down Linux* operating system with a Xen*-enabled kernel that controls the
interaction between the virtualized devices seen by VMs and the physical hardware. The following are
the system requirements for the XenServer host:
One or more 64-bit x86 CPU(s), 1.5 GHz minimum, 2 GHz or faster multicore CPU
recommended
To support VMs running Windows*, an Intel® VT 64-bit x86-based system with one or more
(up to 32) CPUs is required.
Note: To run Windows* VMs, hardware support for virtualization must be enabled on the
XenServer* host. This is an option in the BIOS. It is possible the system BIOS might have
virtualization support disabled. Consult BIOS documentation for more details.
To support VMs running supported paravirtualized Linux*, a standard 64-bit x86-based
system with one or more (up to 32) CPUs is required.
1 GB minimum; 2 GB or more recommended.
Locally attached storage SATA, SAS with 16 GB of disk space minimum.
60 GB of disk space recommended
General disk space requirements for VMs:
Product installation creates two 4GB partitions for the XenServer* host control domain;
the remaining space is available for VMs:
VMs based on the Debian* templates are allocated a 4 GB root device, and a 512 MB
swap device.
Linux* VMs are allocated an 8 GB root device.
Windows* Vista* VMs are allocated a 16 GB root device; other Windows VMs default
to 8 GB.
100 Mbit/s or faster network interface card (NIC). A gigabit NIC is recommended for faster
P2V and export/import data transfers and for live relocation of VMs.

XenCenter* Requirements
The remote XenCenter* application for managing the XenServer* host can be installed and run on any
Windows* 2003*, Windows XP*, Windows Vista* workstation or laptop.
The following are the system requirements for XenCenter*:
