Xen Orchestra 5.54

Last release of the year! The least we can say is that 2020 was not a normal year and we all have been through a lot, we talk about this topic a little bit more on our traditional end of the year infography. Hopefully, 2021 will be better for the whole world. Anyway, we are proud to announce that Xen Orchestra 5.54 is now available and, on behalf of our whole team:

Rolling pool updates

When applying patches, there's often a need to reboot hosts. To avoid any service interruption, you need to migrate VMs around manually. This can be a long and tedious process for any system administrator, especially when you have a lot of hosts in your pool.

The rolling pool updates feature will save you a lot of time and trouble by handling all the pool updates automatically!

Right now, this feature will handle the update automatically and that's it, we are planning in a future release to bring some improvements such as an operation report.

Dom0 Memory set

You now have the ability to manage the memory allocated to Dom0 directly in Xen Orchestra.

We have some recommended values you can use for XCP-ng available on our official documentation

Choose network for multiple VMs migration

Until now, you were able to select the used network when migrating a single VM, but that was not possible when migrating multiple VMs.
With this release, you can now select the network of your choice, even when migrating multiple VMs.

Host maintenance mode

Maintenance mode is a state you can put your hosts in for... well, maintenance purposes.
Activating the maintenance mode will have two effects:

  1. It will evacuate all the VMs on the host to another host available in the same pool.
  2. It will suspend the host, making it impossible to start or create VMs on this host as long as the maintenance mode is active

UI Improvements

Show LUN Serial

When creating an SR via HBA, we are now displaying the LUN serial and ID in the selector.

Sort VM by disk physical size


You can now sort the VMs on the home view by physical disks size.

Remove irrelevant SR from the top SR usage

In the overview section of the Dashboard panel, there is a graph showing you the Top 5 SR usage (in %).

This would have been a relevant graph if we were not showing the udev SR in it, that are, per nature, always 100% used.

We are now excluding automatically these SRs to provide you only relevant information.
