Hello everyone! This is a blog post about our progress on Xen Orchestra 5.0, which is a complete rewrite of the web interface, from scratch (for those who wonder why, read this previous post about announcing Xen Orchestra 5.x [https://xen-orchestra.com/blog/announcing-xen-orchestra-5-x/]). Before releasing it, we

This post is a sequel of our load balancing introduction with XenServer [/blog/load-balancing-with-xo/]. This time, we'll explore the Xen Orchestra [https://xen-rchestra.com] density mode for your XenServer hosts. But why green IT? Because we are about to shutdown your useless hosts "on the fly"

XO 4.15 is out, with a beta of the load balancer, a new dashboard for the self-service, and also a nice list of new stuff: * XenServer VM load balancing [/blog/load-balancing-with-xo/] * Migration queue [https://xen-orchestra.com/blog/beyond-xenserver-limits/] for Storage XenMotion * a complete rework of the XenServer network management

Hi everyone! Today, I'll introduce you a new feature of Xen Orchestra [https://xen-orchestra.com]: live load balancing of your XenServer VMs. As usual here, we'll first explore quickly the concept of load balancing, then the problems, and finally our solution. Concepts Starting with Wikipedia [https:

If you are using extensively the Storage XenMotion feature [https://www.citrix.com/content/dam/citrix/en_us/documents/products-solutions/storage-xenmotion-live-storage-migration-with-citrix-xenserver.pdf?accessmode=direct] in XenServer [https://xen-orchestra.com/#!/xenserver], you probably encountered some limitations. Let's recap first what is XenServer [https://xen-orchestra.com/#!/xenserver] Storage XenMotion and

Coming for the Xen Orchestra [https://xen-orchestra.com] next release (4.15), here is a dashboard dedicated to the resource usage of your configured self-service for XenServer. You can read a recap of the feature itself in our previous blog post: XenServer self service portal [/blog/xenserver-self-service-portal/]. Let's

XO 4.14 is now available with a brand new self-service system plus a full CloudInit support. And as usual, bug fixes and various enhancements. Self-service This is a feature we wanted for a long time. But it's not trivial. Users creating VMs leads to a lot of

This is something our Xen Orchestra [https://xen-orchestra.com] users asked for a long time: a self service portal for creating VMs without bothering the system administrator. But this is not something you make in few minutes, because giving access to VM creation means resource usage, and maybe uncontrolled resource

This is a new article, related to our previous CloudInit [https://xen-orchestra.com/blog/cloudinit-support-for-xenserver/] introduction, and how it works thanks to Xen Orchestra [https://xen-orchestra.com]: without any extra plugin to install on your hosts! Also, if you need help to build a template (or to download our cloud

Welcome to XO 4.13! This one is all about security, stability and fixes, plus UI improvements. One of the major feature is the possibility to use SMB remote for full backups. SMB remotes You can add SMB (ex-CIFS) remotes for your backups. It doesn't work yet with

Here is a new set of benchmarks using latest XenServer Beta (Dundee Beta 2), comparing Xen in PV and PVHVM modes[1]. And on a decent hardware (Haswell CPU with AVX2 instructions). Last benchmarks we made 2 years ago [https://xen-orchestra.com/blog/debian-pvhvm-vs-pv/] gave roughly +15% boost on PVHVM

Happy new year! And happy new release :) This one add 2 major things: continuous replication and continuous delta backup for your XenServer hosts. Without having any extra hardware or software to install, only with Xen Orchestra [https://xen-orchestra.com/#!/?pk_campaign=blog_4.12]. VM Continuous replication Protect your VMs

What about having a continuous replication system for your XenServer VMs without any storage vendor lock-in? We just did it in Xen Orchestra [https://xen-orchestra.com/#!/?pk_campaign=blog_continuous_replication]. You can now replicate a VM every xx minutes/hours on a any storage repository. It could be on

Less than one month after our first release of XenServer incremental backup [/blog/xenserver-incremental-backup/], we made a major improvement inside Xen Orchestra [https://xen-orchestra.com/#!/?pk_campaign=blog_continuous_backup]: Continuous Delta Backup. And we are very happy to present you this exclusive feature on XenServer! It means to backup

Do you ever wanted to create multiple XenServer VMs at once? Until now, you needed to repeat the operation as often as necessary. Boring when you need to create 10 or even 100 VMs! What about now? We added an option inside Xen Orchestra [https://xen-orchestra.com/#!/?pk_campaign=blog_

By ready, we mean: * from the click on "Create VM" * to a SSH access on a 100% working system And also from a generic template: which we can select the disk size dynamically and RAM/CPU. How can it be possible? Using CloudInit! You can find working templates

TL;DR: a working and validated Debian 8 (Jessie) template is available here [https://cloud.vates.fr/index.php/s/jynIvCjhso47nR8/download] if you want.

As you may know in XenServer, you can move a VDI -from a running VM- to another SR (Storage Repository). We exposed this feature almost 1 year ago in our article explaining how to move a VDI in live [blog/moving-vdi-in-live/]. But what about a VDI on a halted VM?

💡This guide is 100% compatible with XCP-ng. In XenServer, the default SR (Storage Repository) is where your VDIs are stored by default. It's very useful for a lot of things, avoiding the user to configure itself for each operation. With Xen Orchestra Just go inside your pool view,

This blog post will explain how to deal with your existing PV guests, when they can't boot anymore. The problem Typically, when you failed your installation of a PV guest, you got: The bootloader for this VM returned an error -- did the VM installation succeed? Error from

Here is some news about a nice improvement coming in the next version of Xen Orchestra: an improved search bar. Our previous search system worked for filtering in live VM/host/SR/pool name, IP address, tags and whatever inside those objects. But what about advanced requests? We wanted to
