    @dsauce To test your theory out on my issue i just tried to disable CBT on XOA side and one vm gave me this error... vdi.set { "id": "11286a97-b773-4ec4-a0b7-464ab87254ca", "cbt": false } { "code": "UUID_INVALID", "params": [ "VDI", "a52fe4ab-edc2-4975-a118-f6db84435379" ], "call": { "duration": 1, "method": "VDI.get_by_uuid", "params": [ "* session id *", "a52fe4ab-edc2-4975-a118-f6db84435379" ] }, "message": "UUID_INVALID(VDI, a52fe4ab-edc2-4975-a118-f6db84435379)", "name": "XapiError", "stack": "XapiError: UUID_INVALID(VDI, a52fe4ab-edc2-4975-a118-f6db84435379) at Function.wrap (file:///usr/local/lib/node_modules/xo-server/node_modules/xen-api/_XapiError.mjs:16:12) at file:///usr/local/lib/node_modules/xo-server/node_modules/xen-api/transports/json-rpc.mjs:38:21 at runNextTicks (node:internal/process/task_queues:64:5) at processImmediate (node:internal/timers:452:9) at process.callbackTrampoline (node:internal/async_hooks:130:17)" } Another vm.. vdi.set { "id": "966fe072-4865-48a2-867a-0eb59b23dcc7", "cbt": false } { "code": "UUID_INVALID", "params": [ "VDI", "d6662a49-0d65-4c4b-a8fa-cddd42ab4cd5" ], "call": { "duration": 1, "method": "VDI.get_by_uuid", "params": [ "* session id *", "d6662a49-0d65-4c4b-a8fa-cddd42ab4cd5" ] }, "message": "UUID_INVALID(VDI, d6662a49-0d65-4c4b-a8fa-cddd42ab4cd5)", "name": "XapiError", "stack": "XapiError: UUID_INVALID(VDI, d6662a49-0d65-4c4b-a8fa-cddd42ab4cd5) at Function.wrap (file:///usr/local/lib/node_modules/xo-server/node_modules/xen-api/_XapiError.mjs:16:12) at file:///usr/local/lib/node_modules/xo-server/node_modules/xen-api/transports/json-rpc.mjs:38:21 at runNextTicks (node:internal/process/task_queues:64:5) at processImmediate (node:internal/timers:452:9) at process.callbackTrampoline (node:internal/async_hooks:130:17)" } Update - after backup completed with warnings i looked back and CBT was re-enabled in XOA. Did not help with my Veeam issues.

    @poddingue Borrow away - "smoke alarm" is a better name for it than anything we had, so we might borrow it right back. Since you mentioned reading the matrix - here is the classification you would be reading, straight from the file: grep access: dadl/xen-orchestra.dadl | sort | uniq -c 49 access: admin 21 access: dangerous 122 access: read 75 access: write 122 of the 267 tools are plain read - that is the entire surface a review-capped agent gets. The other 145 exist in the same file, but for that agent they might as well not. The whole security taxonomy is greppable plaintext - which is rather the point of a declarative format. And if anything in the matrix looks wrong or missing, this thread is exactly the right place - real-world corrections are how it improves.

    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

    Backup timeout with compresion

    Is there any option to set for timeout value? I say this because, monitoring the process, everything seems to be going well until the moment when it starts to check the free space. XCP-NG is 8.2 up to date, the disk on which the VM is it is formated as local ext. The connection to the backup server is on NFS on the LAN at a speed of 1Gb. On the iotop it seems that the space check goes with speed 650Gbits +.

    @darkbeldin For the record, both vm's were running on the same esxi host when exported. This may or may not be a factor (I suspect it is).

    @olivierlambert I've dug into the issue a bit more, and it just gets stranger. Downloading to my Macbook on the same network gets ~4MB/s. This means there is something strange going on with the control domain around remote downloads. When I test the disk speed (which is an Samsung NVMe), the speed is 1.7GB/s: [14:31 xcp-host ~]# dd if=/dev/zero of=testfile oflag=direct bs=1M count=5000 status=progress 4998561792 bytes (5.0 GB) copied, 3.000607 s, 1.7 GB/s 5000+0 records in 5000+0 records out 5242880000 bytes (5.2 GB) copied, 3.15049 s, 1.7 GB/s When I test the network speed with Ookla's speedtest-cli it confirms a 1G connection, and a 1G transit to Europe (checked this twice because 1G Atlantic transits are rare): [14:44 xcp-host ~]# speedtest -s 2023 Speedtest by Ookla Server: LaFibre.info - Lyon (id = 2023) ISP: Bell Canada Latency: 108.05 ms (0.49 ms jitter) Download: 960.47 Mbps (data used: 1.5 GB ) Upload: 172.11 Mbps (data used: 293.4 MB ) Packet Loss: 0.0% Result URL: https://www.speedtest.net/result/c/b8f1da9f-5c57-4ad8-ad3b-729e1625affe On my Macbook (on 802.11ac) I can download an Ubuntu image at ~14MB/s ➜ wget http://ubuntu.mirrors.ovh.net/ubuntu-releases/21.10/ubuntu-21.10-desktop-amd64.iso --2021-11-16 14:49:41-- http://ubuntu.mirrors.ovh.net/ubuntu-releases/21.10/ubuntu-21.10-desktop-amd64.iso Resolving ubuntu.mirrors.ovh.net (ubuntu.mirrors.ovh.net)... 213.32.5.7 Connecting to ubuntu.mirrors.ovh.net (ubuntu.mirrors.ovh.net)|213.32.5.7|:80... connected.

    Well, it's a bit hard to tell you directly what to do vs XOA, because on XOA you are already on a validated OS (Debian) with some packages installed. On which OS did you install Xen Orchestra in the first place?

    Sorry for the huge delay, I just stumbled on this thread It's indeed the case now, XO automatically check the integrity and clean any unused files in VM directory on a remote when that VM is backed up.

    @olivierlambert said in Commands in Xen Orchestra Jobs no longer working: The best solution is to rely on XOA, you know I agree with @olivierlambert! Personally, I'm using XO from sources in my home lab environment -- nothing is "production" and I'm mostly having fun trying to give back to the open source community.

    @Danp - thank you. Yes, I did, but that was not helping in this case. Found the solution: Both machines are on a hostserver, which has NOT all networks. So the real reason must be a network problem, therefore a quite missleading error message After moving both VMs to the master of this pool (which is connected to the same network where the xoa resides), everything went fine. Same storage, same vhds.

    @indyj The file restore issue was due to installing XO on FreeBSD (fine for VM restores, not file extraction). I then installed XO on Ubuntu 20, and this worked for restoring files from Linux VMs but not Windows VMs. Then I installed on CentOS 8 and had the same problem as Ubuntu. I then installed on Fedora 34 and everthing works fine.

    Yes, it should be safe enough to try importing the backup, then starting the VM without network (ie VIFs) and see if it stays up for a few minutes. I think we could start by adding a manual feature and then see in a second step how we could automate it.

    Also, the user will be created only on first connection. Maybe you are thinking about the plugin in a way that's not how it behave.

    @olivierlambert many thanks for the very quick response, it is indeed XO from sources. I think the burst explanation makes sense. Also, thanks for you and your teams continued development and support with both XCP-NG and XO.

    What do you mean "how it works"? It's the same thing than before, just "isolated" from the rest, working in a... worker. And yes, the long run objective is the ability to run it as a service on the remote directly, reducing a lot the merge time (because latency is the worst enemy of merging).
