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

After implementing the XenServer Cloud Init support [https://xen-orchestra.com/blog/cloudinit-support-for-xenserver/] in Xen Orchestra [https://xen-orchestra.com/#!/?pk_campaign=blog_cloud_centos], let's see now how to

We are proud to announce that you can now use the CloudInit system with XenServer, without any plugin to install on your hosts. Only by using Xen Orchestra [https://xen-orchestra.com/#!/?pk_campaign=blog_cloud_support]. Let's see what it can do for you and how to use

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

Since last release [/blog/xen-orchestra-4-10/], we added email notifications for all backup events (full backup [https://xen-orchestra.com/docs/full_backups.html], rolling snapshots [https://xen-orchestra.com/docs/rolling_snapshots.html] or even DR [https://xen-orchestra.com/docs/delta_backups.html]): Not fun enough? So go for XMPP notification then!

Last release of the month! This one is pretty big: * 30+ issues/enhancements closed * 10 new usable features * a lot of improvements * and multiple bug fixes! In few words: we finished the first batch of backup features, and we included a lot of things you'll love :) The official

This article explains how to start automatically a VM when you boot or reboot your XenServer host. Indeed, if for a reason you need to restart your host (or if it reboots for any "non-planned" reason), it's a good thing to have your VM started automatically.

Imagine you lost electrical power for your whole IT room. Luckily, you got an UPS[1], and that's great. But what if power doesn't come back before the batteries are depleted? You have a limited amount of time to shutdown your XenServer hosts, and you probably

Snapshots are a convenient way to rollback your system to a previous state, in other words to "point in time" a disk state. They are: * fast * small (delta) * exportable * and can be scheduled with retention [https://xen-orchestra.com/blog/xen-orchestra-4-2/#schedulerollingsnapshots] in Xen Orchestra [https://xen-orchestra.com/#!/?pk_

When you export a VM (eg for backup purpose) in XenServer, you can use (or not) the built-in compression of the XAPI. In the coming 4.9 version of Xen Orchestra, you can select "Disable compression" for your XenServer scheduled backups: Let's try to compare a

Just after our initial release of Xen Orchestra 4.8 [/blog/xen-orchestra-4-8/], I'm proud to announce that we started to work for a new major release: Xen Orcestra 5.0, the web interface for XenServer. This first milestone of our new 5.x branch will be awesome, believe

Have you ever wanted to copy a VM to another pool or host? So far, you have to do this: 1. export the VM somewhere (on a storage large enough to handle the whole VM size) 2. import the VM on a new host And not only this, you need

This is the (short) story of how we discovered a bug using Xen Orchestra and XenServer [https://xen-orchestra.com/#!/xenserver], then how it was fixed very quickly by Citrix team. > This is me telling calmly but firmly that we found a noticeable bug. Symptoms In short: losing consoles in
