@ovicz I've built xapi-26.1.16-1.2.0.pirq.1.xcpng8.3 on xcp-ng-ndinh2. You can update as usual, then install my packages on top.

@nikade yeah that's hot but would need explaining it as if it were for a 5 years old... asking for a friend :') did they overcome a bottleneck in VDI between SR copy ?

Did a lot of work this weekend and added more to the volume and datapath. in native mode, everything is rbd native including CBT! still working on SXM in tapdisk mode, everything is working with optimized rbd calls except SXM in qemu mode everything works by using qemu-dp and also SXM in MSAPIv3 Huge improvements made, but qemu is the slowest mode due to extra nbt hop. I only provided tapdisk and qemu modes to get more information on how CBT works and how SXM works. Right now I'm using that knowledge to provide SXM over native rbt. I have some good ideas but need to figure out how to make them work. I've also made a backport to ceph v15.2 which runs on dom0 to also include the newer cephx authentication protocol. This is because the ceph dashboard cannot provide a diff between snaps (which is needed for CBT) but a pull request is pending to have this working in the future without the need for rbd userspace. I'll update my git and packages later this week.

@Danp said: I haven't seen a way to do this from within XO. However, you can gather the details using xe on the command line -- for i in `xe snapshot-list | grep uuid | awk '{print$5}'`; do export j=$(xe snapshot-param-get uuid=$i param-name=children); k=$(xe snapshot-param-get uuid=$i param-name=snapshot-time); echo "VM UUID: $j - Snapshot UUID: $i - Creation Time: $k"; done This doesn't sort the results, so you will need to do that in Excel or your favorite text editor. @Danp adding | sort -t: -k4 to your command will sort it by date. -t: set fields separator to : -k4 sort by 4th field

I am not sure if it is the same issue or not. I doing daily replication from: 4 VMs nvme-1 SR vhd --> nvme-2 SR qcow2 2 VMs nvme-2 SR qcow2 --> nvme-1 SR vhd That is homelab for testing only. Xen Orchestra, commit 6a441 [image: 1788116186019-fd87b54f-fe95-449b-8f7e-17c1da61a4cd-image.jpeg] Standalone "Host up-to-date!" with latest august updates. Replication qcow2 --> vhd works as expected. Replication of vhd --> qcow2 creates daily new replica VM and reports this: [image: 1788116670461-b6ae1b45-0735-44b8-b490-c4f89ba3f953-image.jpeg] Log: 2026-08-30T18_42_49.945Z - backup NG.json.txt
