    @olivierlambert Oh okay, thanks for responding. So I turned off SYNC and COMPRESSION on the dataset and retested (by suspending 11 VMs), I immediately noticed a whopping performance improvement (essentially sustained wire speeds AND 50% faster completion time*) : Roughly 984 Mb/s sustained WRITE speeds (during VM suspension) Roughly 984 Mb/s sustained READ speeds (during VM resumption) Transfer time for both READ and WRITE is about 20 minutes (down from 40-45 mins) [image: 1753218219233-screenshot-2025-07-22-170106.png] Gonna retest with SYNC disabled and COMPRESSION re-enabled and see if it degrades performance; standby for another report.

    @DustinB said in Backups started to fail again (overall status: failure, but both snapshot and transfer returns success): @peo said in Backups started to fail again (overall status: failure, but both snapshot and transfer returns success): @olivierlambert Thanks, will update every machine and XO involved in the backup process, and possibly even the individual machines that fails. First failure on vm-cleanup was 15 July, that's a few days before I patched the hosts (as a part of troubleshooting and preventing further failures). Still these backups will (probably) be fully restorable (as I have tested out with the always-failing Docker vm) So you patch your host, but not the administrative tools for the hosts? Seems a little cart before the horse there, no? That's a fault-finding procedure: do not patch everything at once (but now I did, after finding out that patching the hosts did not solve the problem)

    @StephenAOINS This endpoint is not currently present in our REST API swagger, but we do plan to add it to the list of endpoints. We are currently finalizing the migration of existing endpoints, the next step will be adding new ones. We will keep you informed when it is available.

    You can try to "attach" broken VIF to some network and then delete it. Try to use this command xe vif-move If that doesn't work, you can shut down the XO VM, detach the disk, deploy a new VM without a disk, attach the XO disk to the new VM.

    @splastunov said in File restore not finding any option: If nothing will help and you can't import xva with import VM, I have solution. Deploy new VM with disk x4 times greater than backup file. OS Ubuntu 16.04 or later. Copy backup. Take attention. You need always copy backup. Do not move it. Install xva-img https://github.com/eriklax/xva-img add-apt-repository ppa:ubuntu-toolchain-r/test && apt-get update && apt-get install -y gcc-7 cd to xva-img dir and run next command cmake ./ make install Extract xva file tar -xf my-virtual-machine.xva -C my-virtual-machine chmod -R 755 my-virtual-machine In folder my-virtual-machine you will find some directory like Ref :1, but maybe with another number. Remember this number. Create raw disk from extracted. Replace 1 with number from previous step. xva-img -p disk-export my-virtual-machine/Ref\:1/ disk.raw Install qemu-utils apt install qemu-utils Convert raw to vhd qemu-img convert -f raw -O vpc disk.raw [vhd-name-you-like].vhd Copy vhd to some SR. I'm using local SRs, so in my case path is /var/run/sr-mount/[sr-uuid] Go to the host, cd to SR folder, get VHD uuid, rename VHD cd /var/run/sr-mount/[sr-uuid] vhd-util read -p -n [vhd-name-you-like_from-step-8].vhd mv [vhd-name-you-like_from-step-8].vhd [uuid].vhd Rescan SR Attach VHD to existing VM or deploy new one Get you files wow. I am getting on with this in parallel. Thank you again! Results for both suggestions and requests are coming!

    I am no iSCSI expert, I don't know if this settings exists, but before tinkering I would do some benchmarks.

    @vincentp I'd personally go with a 10GbE switch just to be sure there are no bottlenecks from that, I don't really think you'll hit full 10GbE for a replication job but it's better to alleviate that IMO.

    @abelaguilar Sounds good, yeah I think that is the easiest method to go about it, rather than direct attached networking.

    How to get 10gbe speeds on guest VMs?

    @RaHu In theory you would want to change the MTU of parent interface in OPNSense to 9000. In my case testing is not possible since I run all vlans off a since interface (2x10gbe NIC) and do not want to change the MTU of systems outside my virtual environment. Anyways, with the change mentioned above you achieve 10gbe speeds between VMs.

    @SNSNSN Indeed, these would typically at least be isolated via vlans at least (one vlan for iscsi traffic, one for iscsi). There's no point in having them in two different subnets if they're in the same network and vlan, the traffic isn't isolated at all. You might as well have them in the same subnet if you're doing that, in which case you only need 1 IP on the XCP-ng management NIC.

    What do you mean by "performance to local storage was equivalent"?
