    Is a centralized XOA server "managing" two remote Proxy-fronted XCP clusters supported with the SDN Controller Plugin? We are looking to deploy an architecture similar to this blog post from 2022: https://xen-orchestra.com/blog/xo-proxy-a-concrete-guide/

    Small follow-up on the NBD connections idea, because I asked internally and it turns out that was not a false lead at all. The number of NBD connections is capped per host, so 20 per disk is well past what the host will actually hand out, and it is worth turning down whatever else is going on in this thread. I do not have the exact ceiling yet. I have asked the XAPI side for the real number and I will post it here once I have it, because guessing at it would not help anyone. @Andrew, that fits your side too as far as I can tell, since you are at 1 and have seen this once rather than constantly. probain, I will send you an upload link by direct message so you have somewhere to put the logs. I still do not know whether the fallback itself is new this week or simply newly visible, so please do not read anything into my message on that part.

    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

    New releases! Terraform Provider Xen Orchestra v0.40.0 This new release allows users to import VMs directly from Xen Orchestra into Terraform without recreating it or modifying manually the Terraform state. There is still some drift when importing it, but nothing that changes the real state of VM and we are currently on it! https://github.com/vatesfr/terraform-provider-xenorchestra/releases/tag/v0.40.0 Golang SDK for Xen Orchestra v1.17.0 v2 The network service is now available from the v2 client! You can now create, get and delete your network directly from it! v1 & v2 The template value in VM struct params has been fixed, We can now get the template id directly from it. https://github.com/vatesfr/xenorchestra-go-sdk/releases/tag/v1.17.0

    Migrate it to the host that will be the master (even local storage of the master). Then you can add any slave.

    Yes, setting concurrency to 1 helps me. Will try to run concurrency >1 on th pool and see how it works. When concurrency > 1 it would be nice to split backups per-host (in case of pool) or per-SR (in case of multiple SRs)

    @LEB-ID It's called Add new Server in XCP-ng Center too... old habits die hard. But Pools is not the right word either. It's hard coming up with something short and precise.

    @olivierlambert said in Backup-NG Error "invalid header checksum" after VM-Disk-Resize and reaching retention Limit.: So the issue appeared just when the oldest extended delta had to be merged in the full I suppose. This is exact, but we need to have a proper process to reproduce it. This might be related to: increasing the size of the disk above a certain threshold increasing the content of the disk above a certain threshold

    After: mount 192.168.10.6:/mnt/raid/nfs /mnt/jan and i look with mount i get this: 192.168.10.6:/mnt/raid/nfs on /mnt/jan type nfs4 (rw,relatime,vers=4.1,rsize=131072,wsize=131072,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=10.211.55.19,local_lock=none,addr=192.168.10.6) So its working. After manual typing what XO tried: mount -t nfs 192.168.10.6:/mnt/raid/nfs/backup /mnt/jan -o vers=3 I get the same error: mount.nfs: access denied by server while mounting 192.168.10.6:/mnt/raid/nfs/backup So the “-o vers=3" option is the problem. Can i edit a file in XO to get rid of the “-o vers=3” option? SOLVED In XO i used the option -o vers=4 and this works.

    @olivierlambert said in Continuous Replication fails with VDI_IO_ERROR(Device I/O errors) on fresh XOA install after XenServer 7.2 -> XCP-ng 8.0 upgrade: To your config file, yes. Where this config file is depends on where do you installed Xen Orchestra (I suppose from the sources, so I can't guess where do you installed, could be anyware ) edit: I think it's fixed now and integrated by default in the config Great, this fix already is in the new version. I was having this problem (Error: VDI_IO_ERROR(Device I/O errors)) and was not be able to do CR of my VMs but now CR works. Thank you PS: BTW that was my config file

    When you click on the link of the error message it should send you to the official documentation, explaining what it means: https://xen-orchestra.com/docs/backup_troubleshooting.html#error-messages I'm not sure to understand the UI question, can you post a screenshot?
