Clonezilla is my go to for doing that. I have a tutorial where I should how to migrate from Virtualbox to XCP-NG here:

@olivierlambert

I work with enterprise companies and they NEED those reminders to let them know they should be using the supported version. I don't really see them as annoying at all.

@bullerwins

It's a wonderful feature, you can have customized filters for VM, storage, Templates, and Pools. Combine that with using lots of tags and it makes larger deployments very manageable.

@CodeMercenary

Under the xo-vm-backups directory is a series of directories named with UUID's that contain everything that belongs to a particular VM's backup. As long as you keep each directory and all the contents nested within it you will be able to restore that VM.

@jasonnix

That is enough to get it working and fine for most homelab environments.

@MichaelCropper
I recently did a video tutorial on how XCP-NG virtual machine dynamic memory management and over allocation works.

XO will utilize the existing VM disk or snapshot as a base, restoring only the differential data to a new disk saving time. More details are in this blog post

@abudef
Yes, as far as I know the only way to restore a VM but keep all the GUIDs the same is to roll back a snapshot.

@starmood For each VM backup run inside of Xen Orchestra it backs up not just the VHD but everything that is needed to restore that VM to any other XCP-ng host. So in a complete loss situation you can load a new XCP-ng Host, setup Xen Orchestra, point the new Xen Orchestra to those backups and restore any of the VM's with all their settings.

The metadata backup of XCP-ng is just that, the metadata of the system and it's not granular. It's good to have because all the things like network setting and what VM's are on the hosts will be there, but the VM backups to me are the most important.

I have a tutorial covering how the backups work, it's from a bit over a year ago and there are EVEN MORE features now and I will be doing a new video this year to cover that.

I also have a tutorial on how you can also automate the backup validation process

@Matteo

If the storage type you have the VM is thick provisioned it will take up more space. Use a thin provisioned storage for better storage efficiency
https://xcp-ng.org/docs/storage.html#storage-types

If you choose 2 storage destinations it will copy to each of them at the same time.

@tuckertt

Not a direct answer to your question, but something to think about. I get that connecting XO to Active Directory is good for centralized identity management and offers rasier onboarding/offboarding, one password to rule them all. But the reality is that once AD is compromised, attackers can pivot straight into the virtualization layer — the crown jewels.

@coolsport00

Sounds like you have some issues either because you are changing the IP's after you setup the pool or you are having

I cover how to deal with host failures in this video:

@coolsport00

Yes, always have all systems to full patch level before adding them to pools.

Also, I don't recommend using Xencenter just use XO.

For clarification the platform has been around and in use for a while. The Xen hypervisor was first released in 2003 then Citrix Xensever around 2007 with XO first being released in 2013. XO has been around since 2013 first to manage Citrix and then Vates released XCP-ng in 2017. XO Still works with both platforms.

@coolsport00

I have been using XO & XCP-ng for years now for many of our commercial clients and it's a very solid platform.
While there is a lot of good documentation for XO & XCP-ng first starting out with a new virtualization platform can be a steep learning curve which is why I have a series of videos that are designed to help people get started on the platform. Hope you find them helpful.

@abudef

It's a new VM so it get's a new GUID. Why would you want it to have the same one? Also if you keep the snapshot when doing a delta backup you can roll that VM back and keep it's GUID.

@thomas-wood "Remotes" are for XO backups and SR are for VM Storage. Once you add a SR to a pool it's available to all hosts. Also, all hosts should be able to access the IP of the NFS server before setting that up.

I have a video explaining storage in XCP-ng here:
https://youtu.be/xTo1F3LUhbE?si=QHYkABgElsEVOj6H

@thomas-wood Yes, go with TrueNAS Scale. Also, TrueNAS Scale will be called TrueNAS Community with the next version 25 release.

Why are you doing this with TrueNAS Core? It has reached end of life.
