    @paco On the stuck server, could you warm migrate the vms to one of the other hosts? Or could you shut down a VM at a time and cold migrate them? The second option is certainly not ideal, but maybe?

    Hi, Latest XOA, with fully patched XCP 8.3 here. I'm fiddling around again with NBD+CBT in backup jobs (was avoiding CBT for a time, to reliably control my backups and avoid unnecessary KEY points) in the context of THICK SRs to spare some space. I know that CBT is reset when migrating from one SR to another. But here is what I encounter : VM has no CBT enabled on its VDIs, it is on a SHARED SR in a pool of 3 hosts backup option changed for NBD+CBT, was only NBD before CBT is enabled on the next run by the backup job, I get a delta (was expecting a FULL ?) next run, delta, as expected i migrate this VM on another HOST, without changing its SR CBT is immediatly disabled ? why ?? next run of backup it tries a delta, but "fall back to a full" (normal as CBT has been disabled...), and do a KEY point on the remote next run is a delta as expected does this mean if I do a rolling pool update or host maintenance that will move the all VMs around, all CBT will be disabled and I should expect a FALL BACK TO FULL on all my NBD+CBT enabled backup jobs ??! why disabling CBT on a change of HOST and no move of SR ?

    But giving your feedback on how you solved it might help many people in the future Thanks!

    That's correct @mauzilla We use a VHD chain on destination so it's equivalent to get "snapshots" of a VM So it's delta everywhere with the same full parent for the same original VM.

    The delta isn't computed over the network, but directly on the host itself

    @slynch OK, that's very good news then! Debian was still having issues where any configuration applied via cloud-init would just be added to the existing default DHCP config, unless you took care to build the VM without the default interfaces config beforehand.

    @olivierlambert said in PCI Passthru Error not working on 8.2 but was 8.1: Hi! IOMMU should be enable in the BIOS. Double check that Also please share your grub config to see if it's correctly written. After playing with it more, the issue appears to be passing multiple devices of the same type. In this case RADEON WX7100. If I take it down to one card it works as expected. If I add more than 1, pick any quantity, then I run into the issue. The issue goes away once I reboot the host, and then I can assign a card, but the second the VM reboots the error comes back

    This can happen from time to time on master (despite we do every "broken" code in dedicated branches), sometimes you can have a surprise. That's why it's important, before anything, to get the latest commit and rebuild, to see if the issue persist. If it's the case, then reporting the problem will be helpful

    The best way would be to use XO Proxies as "Reverse HTTP proxies" (or any reverse proxy in each DC) and then tell XO to connect to those proxies. This way, each DC will have only one entry point exposed to the outside, and you could manage that with your central XO. This is a subject we planned to work in the next months. If you have a support subscription, please open a ticket so we can do initial test inside your infrastructure

    @magtech If you want to do a XOA quick deploy, you need a working internet connecting and outbound port tcp/8888 must be open to the internet. New install of XCP-ng, can't complete Quick Deploy might help?

    Yes, that's what i want to do. But at the moment it create an snapshot for each cron that I made and I want to have only one snapshot and to be reset to full backup on Saturday. In essence, I want to have only one snapshot to an VM no matter how many cron I have attached to the replication. In this case, I want to reset the Continuous Replication chain when the server is least busy, not after a number of replications

    I also encountered this problem. If you are using Debian you can use pre-packaged XO from sources https://github.com/mathiswolff/xen-orchestra
