    @florent Thanks for your reply! We have started to migrate thousands of VMs, so disk transfer speed is important for us.. We will also do our detailed tests soon with different threads setting and publish it here. I think threads=1 is a good and logical default, but not efficient. Others might complain if you set it to a higher value. Configuration option would be a real good solution.

    @skipthompson81 said: this CONFLICT is not OK! You will need to provide more details about this specific backup job. It's possible that the backup succeeded, but then the subsequent Health Check failed or timed out. Have you tried downloading and examining the full log from the failed backup?

    Hello I'm pulling stats for all VMs to understand CPU usage. We're a bit behind the curve in terms of XO versions, but these questions hopefully are still relevant. If using a granularity of days, the interval is set to 86400 (understandably) but the endTimestamp varies. Running this on June 9th @ ~1740 we get timestamps for both Mon Jun 8 01:00:00 AM BST 2026 and Tues Jun 9 01:00:00 AM BST 2026. Does this average across the day? Why is the timestamp 0100? Why would there be different timestamps between VMs (all are running) and does that mean that the figures are misaligned in the results? These are retrieved via curl and a bash script, a bit hacky, but for clarity the request is: ++ curl -X GET -s -H accept:application/json -b authenticationToken=[[REDACTED]] -o [[REDACTED]] 'https://[[REDACTED]]/rest/v0/vms/[[REDACTED]]/stats?granularity=days' Really keen to know if we can control the start and endtime, as well as provide a manual interval, as well as the aggregation strategy (min, max, average). Are any of these possible? Lastly, is cpuUsage the percentage as per the dashboard, but averaged over all CPUs? Thanks so much in advance. James

    You need to use LDAP plugin to enable user login with XO. Please refer to our official documentation: https://xen-orchestra.com/docs/ldap.html

    This is an idea I had a long time ago (issue created in 2016), but due to the lack of request for this, it's not a priority. Obviously, if you have pro support, creating a ticket to get this could raise the priority of dev teams. Also, contributions are very welcome

    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
