    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

    Thanks both, agreed, in hindsight this should be configured on the VM itself as it could lead to unexpected issues (like maintenance and having VM's start by themselves) Thanks for the input

    Here is a good explanation: https://docs.citrix.com/en-us/xencenter/7-1/dmc-about.html Static can only be set while the VM is offline. Dynamic can be changed in live. When you'll live migrate a VM, it will be decreased to the dynamic min. So take care to use a value that's higher than your VM operating system minimum RAM usage.

    That's a way to do it. Use smart backup on tags. Eg a tag called "delta only" and a tag "delta+CR", so you'll be sure to assign the right tag to your VM

    No. The parent folder. XO will search for the folder xo-vm-backups directly edit: if your share was previously <NFS_IP>:/myshare, then you should use this very same one, and NOT <NFS_IP>:/myshare/xo-vm-backups

    There's 2 reasons: XAPI doesn't tell us if the transfer is complete or just cut. We just stop to receive chunks, and after a bit, we decide that's it, there's no more data to send (that's the normal behavior even when it works!) XVAs are hard to validate, depending on various factors. We do a VHD validation (so for delta backup) but XVAs are another thing

    On the remote side, right? It won't be "dedup" if it's your question (for now at least). We are thinking on a smart way to dedup it efficiently It's not trivial because we don't have a lot of control on the host itself, but we might find solutions.

    @nraynaud well i just used the datastore browser to download the vmdk. i did the same thing with some other (smaller) VMs without any problems. All of this from the same ESXi host. Thanks for looking into it though, i will try the export VM way next but have to find the right time for a shutdown ...

    That's correct @mauzilla We use a VHD chain on destination so it's equivalent to get "snapshots" of a VM So it's delta everywhere with the same full parent for the same original VM.

    The delta isn't computed over the network, but directly on the host itself

    @slynch OK, that's very good news then! Debian was still having issues where any configuration applied via cloud-init would just be added to the existing default DHCP config, unless you took care to build the VM without the default interfaces config beforehand.
