    I spoke too soon. The issue has returned the following day which means it is most likely the nightly backups triggering the issue.

    @gcpeters4 said: @john.c This is a good idea as well. If the previous suggestion of trying to do a DNS round robin approach doesn't work, this may be my best option. Thanks for taking the time to provide your suggestion! By the way my suggestion is recommended best practice from Microsoft for their Active Directory software and/or technology. My suggestion will be more likely to work if your DNS servers and requests have issues with Round Robin configuration. Plus with my solution you can easily add more servers as domain controllers to the cluster, as required and use replication to keep them consistent and up to date.

    the last rewrite of the stream processing ( spring 2025 ) focused on stability and memory footprint, and , on a standard cpu, it tops at around 300MB/s per backup job. Your benchmarks are very interesting, and they confirm most of it. this limit was not really an issue since, in most case the xapi was limiting around 100MB/s per disk , but it will be more a more visible limit Note that master have some fixes on the memory usage (not related to backups) That's why we have started an internal workforce focused on performance, with all the teams from the kernel to the backups, including storage, network and xapi. If I can brag a little : [image: 1779106650898-afd7b59b-a4f0-4a92-88ee-2c7ba52d18bf-image.jpeg] i9 , nvme disk , backup to a nvme disk in passthrough, xoa and vm are on the same host, so it's quite far from real world data, but it shows where the limit is

    XOA supports CH 8.0, what's your error? XOA use another mechanism because CBT isn't really worth it (we use delta VHD instead, which is compatible even with XS Free)

    We patched some part of SMAPIv1 to "make it work" (our patches were even merged) but VHD export is another (more) complicated story. That's why we are working on SMAPIv3 now instead wasting resources on the "legacy" storage stack

    XOA: VMs' consoles don't work ("Unknown key pressed, Unknown key released")

    @Danp said in XOA: VMs' consoles don't work ("Unknown key pressed, Unknown key released"): What version of XS / XCP? Are you fully patched? XOA is on XCP-ng 7.6 which I installed 3 weeks ago and then updated with yum, so still up-to-date, I believe (not trying to update at the moment as I'm in a process of migrating and don't want any reloads/restarts of XCP-ng. VMs were on XenServer 6.2 updated with all patches available. Additional info: one of the Linux VMs which I tried to use XOA's console with, was already on XCP-ng 7.6 (the same as XOA) and here behaviour was different (but bad anyway): hitting Enter was giving newlines, AFAIR, but the console wasn't reacting on other keys. This may help -- https://xen-orchestra.com/blog/xenserver-consoles/ Thanks. Though I'm not sure which keyboard layout the blog mentions... Of the browser (client)? Of the host with XOA? Of the host with the VM observed on the XOA's "console"?

    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: [image: 1556589256050-fc439a0c96cb13a0b2b11b3bd80ff3be.png]

    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.
