Installing XenServer for CloudPlatform
If you want to use the Citrix XenServer hypervisor to run guest virtual machines, install XenServer
on the host(s) in your cloud. For an initial installation, follow the steps below. If you have previously
installed XenServer and want to upgrade to another version, see Section 4.4.1, “Upgrading to a New
XenServer Version”.
8.1. System Requirements for XenServer Hosts
• The following versions of XenServer are supported:
• XenServer 6.2 (with fresh CloudPlatform installs; if you are upgrading from a previous
CloudPlatform version, XenServer 6.2 is not supported)
• XenServer 6.1.0
• XenServer 6.0.2
• XenServer 5.6 SP2
• XenServer 5.6 FP1
• The host must be certified as compatible with the XenServer version you are using. See the Citrix
Hardware Compatibility Guide: http://hcl.xensource.com
• You must re-install XenServer if you are going to re-use a host from a previous install.
• Must support HVM (Intel-VT or AMD-V enabled)
• Be sure all the hotfixes provided by the hypervisor vendor are applied. Apply patches as soon as
possible after they are released. It is essential that your hosts are completely up to date with the
provided hypervisor patches.
• All hosts within a cluster must be homogenous. The CPUs must be of the same type, count, and
feature flags.
• Must support HVM (Intel-VT or AMD-V enabled in BIOS)
• 64-bit x86 CPU (more cores results in better performance)
• Hardware virtualization support required
• 4 GB of memory
• 36 GB of local disk
• At least 1 NIC
• Statically allocated IP Address
• When you deploy CloudPlatform, the hypervisor host must not have any VMs already running
Warning
The lack of up-do-date hotfixes can lead to data corruption and lost VMs.
