    @florent said: where does this disk comes from From my Redhat 10 @florent said: if you have access to your SR from the outside, you can also put the qcow2 file directly I create a VM to be a NFS to access the 3 HDs, the qcow disks are on the Redhat 10 that I was trying to import from. Do you mean I put the qcow disks on one of the HDs and access them when I create a VM?

    @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.

    Hi there. Using XCP-NG 8.3 with XO from sources. It was 6a5eb1205 (already updated it). There was active backup task with "temporary disabled" hover on cancel button. But nothing active in task menu. After shutting down "Importing....." VM and rebooting the host for a second time, VM starts again. VM had autostart ON and "continuous replication" tag. Maybe the "lock" for disabling the autostart is applied only after the task is done? Today I will try replicate the issue with some testing VM.

    Because there's a ton of dependencies, and we try to decouple things, this work takes time. We should be able to run on a more recent version of Node soon, and when it will be the case, our doc will be updated accordingly. That's exactly why we can't support 3rd party installers. Our doc might change and during the interval, if the 3rd party installer isn't following, then it will break.

    OK, seems I wasn't trying hard enough. I was trying to mount the tools under the iso list, but when I look further down the list to xc-ng Tools it turns out I can mount the tools from there as long as I do it manually (mount /dev/sr0 /media/blahblah). Installed now, all good.

    There's no tool to "merge" old forum or fetch old message. So for few months we'll still have old XO forum then it will be automatically redirected to the XO category here.

    It's just a missing info in a config file of the appliance. Not a big deal, just surprising to see that now, despite the fact it was there before.

    XO Delta Backup Fails to Local Storage Mounted via NFS

    Hi, So I tried using the NFS target remotes but the speed of transfer was very poor even though the connection from XO to the NFS server is over 10Gbe. XO is on the same XCP-ng host as the VMs being backed up. This XCP-ng server is connected to the NFS mount over 10Gbe network: [image: 1581002643082-56cc5a0a-e633-443b-9a50-6575ef5cddaf-image.png] Here is the NFS Remotes setting in XO to the backup server (FreeNAS) at IP 10.10.2.3:[image: 1581002745614-046fcdaa-8788-4d69-aa00-c1620a0afb46-image.png] The backup logs show extremely low transfer speed: [image: 1581001993532-b51d304d-2fb6-472f-8eb9-0dbec967d49c-image.png]

    @olivierlambert Thanks again for the reply. I’m looking into it more. I think I need to add the storage directly to the VM running XO. I was trying to use a drive connected to a drive on my local network. Though it says it can talk to the drive, it does not reach it. I’m trying now to add an NFS to the XO server.

    You can avoid transferring some disk data with the [NOBAK] title in the VM disk. However, a VM snapshot isn't capable of ignoring a disk. This would require a change either in the way we do backup in XO (not using VM.snapshot, but VDI.snapshot instead) or modify XCP-ng API to support VM.snapshot with excluded disk. The first option will make quiesce snapshots impossible. The other one is a bit more complicated to realize, but not impossible. The issue already exists in our bug tracker: https://github.com/vatesfr/xen-orchestra/issues/2560 julien-f created this issue in vatesfr/xen-orchestra closed [Full backups] Supports `[NOBAK]` #2560

    This may be related to https://github.com/xcp-ng/xcp/issues/282 My guess is that the tools ISO was mounted into the XO VM, then updates were applied to the host that contained an update of the tools ISO, which led to the XO VM having an non-existing tools ISO still mounted. I have made a change in 8.1 to avoid that (eject all tools ISOs after updating the ISO, not just from shutdown VMs), and testing will tell us whether that's a good solution. To solve the situation, you usually just need to eject the ISO with xe vm-cd-eject, not xe vm-cd-remove, as @tuxen said. If you had a snapshot of the VM before removing the CD drive, I think restoring it should bring the CD drive back and then you can eject the CD with xe vm-cd-eject... Unless restoring the snapshot also fails. Else as tuxen said you need to recreate a CD/DVD device and attach it to the VM. iw0der created this issue in xcp-ng/xcp closed This operation cannot be performed because the specified virtual disk could not be found #282

    It's pretty simple: just replace "xva" in the image by VHD and that's it. Otherwise it's explained https://xen-orchestra.com/docs/delta_backups.html If you still have questions, let me know
