    In case anyone wonders how this played out. At the end of the day, I shutdown the host with the running workloads on it, kept it at BIOS boot so the 8.3 installer would upgrade it cleanly, and then booted it back up. For reasons related to my particular setup, the down time was more than 60 minutes. But that's not related to XCP-ng. The XCP-ng installer was maybe 10 of that. 20 of that was 3 reboots on a server that takes ages to boot. One thing that is a bit difficult is that the 8.3 installer doesn't notice ZFS volumes or help with ZFS. So after the upgrade, I have to follow a modified set of these instructions (modified because the package names have changed over time) to install ZFS and its components into the system. So the sequence is: Shutdown Install via ISO Reboot to single user mode Run yum update to pull in all the updates Run the ZFS commands to install ZFS on the host Reboot again Run normally Of course, I ended up rebooting more than just those 2 times, because I forgot that I would need to install ZFS (even though I did it on 2 different hosts already ) So now the pool is fully upgraded, everybody is happy. I'm now working on creating shared storage across the nodes. It's amateur hour over here. I appreciate all the help.

    @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.

    @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.

    @rochemike sorry for the late reply! If we already have an ISO on an SR, do we even need to mount the ISO for a network build of Centos/RHEL? Isn't... shouldn't it be possible for the ISO to be mounted by the new build VM as source for creating the new VM, instead of using network build? That is exactly what packer-plugin-xenserver#56 accomplishes. The new VM mounts the guest tools to the DVD - which I don't even want to use as I prefer to install a package afterwards. Is it possible to mount the RHEL/Centos ISO instead? I believe the ISO and guest tools are treated the same -- both VBDs are attached as cds. If you can identify what is different about them in the UI or from the xe cli that would help me understand what you trying to describe. As for what is possible, if what you want to configure is accessible via the XCP-ng / Xenserver API the packer plugin could be enhanced to perform that action. Hope this helps explain more on the potential possibilities.

    @dredge999 yeah in hindsight thats what I should have done I wonder if I can restore the config files and have the VM operational again. It's more getting it to stop now without a host restart
