XenServer High-Availability Alternative HA-Lizard

WHY HA AND WHAT IT DOES XenServer (XS) contains a native high-availability (HA) option which allows quite a bit of flexibility in determining the state of a pool of hosts and under what circumstances Virtual Machines (VMs) are to be restarted on alternative hosts in the event of the loss of the ability of a host to be able to serve VMs. HA is a very useful feature that protects VMs from staying failed in the event of a server crash or other incident that makes VMs inaccessible. Allowing a XS pool to help itself maintain the functionality of VMs is...

PCI Pass-Through on XenServer 7.0

Plenty of people have asked me over the years how to pass-through generic PCI devices to virtual machines running on XenServer. Whilst it isn't officially supported by Citrix, it's none the less perfectly possible to do; just note that your mileage may vary, because clearly it's not rigorously tested with all the possible different types of device people might want to pass-through (from TV cards, to storage controllers, to USB hubs...!). The process on XenServer 7.0 differs somewhat from previous releases, in that the Dom0 control domain is now CentOS 7.0-based, and UEFI boot (in addition to BIOS boot) is supported....

Better Together: PVS and XenServer!

XenServer adds new functionality to further simplify and enhance the secure and on-demand delivery of applications and desktops to enterprise environments. If you haven't visited the Citrix blogs recently, we encourage you to visit https://www.citrix.com/blogs/2016/10/31/pvs-and-xenserver-better-together/ to read about the latest integration efforts between PVS and XS. If you're a Citrix customer, this article is a must read! Andy Melmed, Senior Solutions Architect, XenServer PM  

Set Windows guest VM Static IP address in XenServer

A Bit of Why For a XenServer Virtual Machine(VM) administrator, traditional way to set a static IP to a VM maybe not that direct. That is because XenServer do not provide API to set VM IP address from any management tool in history. To change the IP setting for a VM in XenServer, you will need to email the VM user and let them to do the setting manually. Or you may need to install some 3rd party tools to help you to set the IP address to the VM. For create new VM for users by VM clone, set IP maybe means multiple time of...

Enable XSM on XenServer 6.5 SP1

1 Introduction Certain virtualization environments require the extra security provided by XSM and FLASK (https://wiki.xenproject.org/wiki/Xen_Security_Modules_:_XSM-FLASK). XenServer 7 benefits from its upgrade of the control domain to CentOS 7, which includes support for enabling XSM and FLASK. But what about legacy XenServer 6.5 installations that also require the added security? XSM and FLASK may be enabled on XenServer 6.5 as well, but it requires a bit more work. Note that XSM is not currently a user-visible feature in XenServer, or a supported technology.This article describes how to enable XSM and FLASK in XenServer 6.5 SP1. It makes the assumption that the reader is...

Making a difference to the next release

With the 1st alpha build of the new, upcoming XenServer release (codenamed " Ely") as announced by Andy Melmed's blog on the 11th October – I thought it'd be useful to provide a little retrospective on how you, the xenserver.org community, have helped getting it off to a great start by providing great feedback on previous alphas, betas and releases - and how this has been used to strengthen the codebase for Ely as a whole based on your experiences.   As I am sure you are well aware - community users of xenserver.org can make use of the incident tracking database...
