  What you found is a pretty old and outdated thread, and conclusion is: It's not limited - and there's no real difference between 1 and 10GE. In case it's limited to protect mgmt-int, it would scale with 10GE, but in fact it doesn't.

  Use a single partition because this is a nice way to let cloud init grow the system disk if needed. I made a guide a while ago about doing this on a Debian, it's exactly the same principle: https://xen-orchestra.com/blog/debian-cloud-template-for-xenserver/

  I ran into something VERY similar with XCP-ng and\or XOA a while back - ended up with close to 200 new "clients" showing up on my Meraki gear. They weren't even "connected" long enough to register as IP clients, only MAC clients (ARP, possibly). I didn't think much about it at the time, as both the MAC addresses and hardware information didn't seem to be tied to any actual device by some manufacturer. I may be able to pull those out from my client history... EDIT: Here is a small section of that list:

  To get assistance on XOA, since you have support, it's better to go with our support ticket system. This way, you can be sure to have an answer with direct developer access in a guaranteed amount of time. Please open a ticket here: https://support.vates.fr/#/tickets XOA isn't dealing on what's inside on the VM: it's an hypervisor-level agentless backup solution. As soon you create the ticket, we'll take a more in-depth look about details (what kind of backup are you using? Delta or full etc.) and also if there anything special we could do at our level.

  I don't know what's the /xen path? Install via this docker isn't the official/documented way, so it's hard to assist. Please try to build it according the doc and double check if reverse work as documented too. Otherwise, it's an issue of the Docker you use with our doc, so you'll better time to create an issue on the 3rd party "installer".

  It depends where you decided to install it (basically where you cloned to repo). Also remove the redis database if it's only used for XO.

  If you didn't, I strongly suggest that you watch the live YT webinar I did on XO backups. IIRC, there is a part talking about smart backup. https://www.youtube.com/watch?v=FfUqIwT8KzI

  You have a problem on your XCP-ng, this is not related to a XO issue. It's stuck doing a snapshot, which is really a basic operation that shouldn't fail at all. Double check your SMlog on the host.

  It looks like I can remove the remotes and set them up again, and configure the backup jobs to address the new share. That's okay, there are not too many.

  You need one XOA, connected to both pools. It will stream the VM content (delta) from the source to the destination. You don't need any directly link between your SR in both DCs. You DCs can be isolated with just one XOA connected to both, and it will work.

  No XCP-ng/XenServer workaround, it's a "built-in"/by design limitation (it's considered as "stalled"). So your goal would be to avoid these extremely long tasks (ie: to finish before the task is destroyed)

  You'll end up with a chain, yes (so every read will need to make "hops" on each member of the chain). Longer the chain, slower the operation. But it shouldn't be too catastrophic either (for a heavily IOPS loaded VM, you'll notice the difference, but not in other less IOPS hungry scenarios)
