    @stormi I really appreciate the continued help. I'm not sure it works. On my single-host pool master—the one I want to join into my half-upgraded pool—I run the command: xe host-emergency-disable-tls-verification It returns with no errors. If I do xe host-param-list and look through the parameters for my host, I see: tls-verification-enabled ( RO): false This is the only thing I see documented that can turn off TLS verification. If some other command like pool-uninstall-ca-certificate would have the effect of disabling TLS verification, I can't see that documented anywhere. In fact, even though xe pool-uninstall-ca-certificate appears to be a valid command that my xe binary knows about, I can't find that particular command documented at all. Even after the emergency-disable-tls-verification, if I attempt to join that host to the half-upgraded pool (using xe pool-join...) I get: Error code: POOL_JOINING_HOST_TLS_VERIFICATION_MISMATCH It seems like even though the host has TLS verification off, the fact that its pool has verification enabled is blocking the action.

    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 ?

    @vmpr Not much, this is a system issue which means that it's either due to your NFS server or to the connection between your XO and the NFS server. First, try to unmount the share and restart xo-server, if it keeps happening, restart the whole machine on which XO is. If that does not help, you should mount the share manually and do some tests directly on it.

    Most users are relying NFS shares. However, we are open to build something for tapes. The problem is: we have no knowledge on that technology nor have any tape system in our lab. If there's enough traction for this, or even sponsored dev to do it, we'll be happy to work on that!

    @olivierlambert XO does not test the full VHD structure because that would be too long, but does check both the begining and the end of the file (and all other VHDs in the chain) before each backup to make sure the files were not truncated. For full backup we are using a simple heuristic to attempt to validate XVA files, but it's very basic and unfortunately it does not applies to compressed files.

    @julien-f I believe that you already updated the docs, but that occurred after the postings above. You may want to review the section discussing forever-service to be sure it doesn't need modified.

    @s-pam i'd say use them, always use the. Only a few KB of space and could be every handy. We have 3 servers in the pool so overlooked requirement for full pool recovery. (p.s we didn't fail, it's during DR testing it was flagged) we had the backups on already and if this had been a real issue, would have saved a lot of bacon!! turn it on ! (and check you can get it without a running XOA for quicker restore in full meltdown.)

    This section has nothing to do with XOA IP address, but useful to restrict some VMs to some IP address. I agree it's unclear. But as I said, for now, there's 0 GUI to configure the system per se. That's why I said it could be an addition sure, but there's nothing yet, so adding it will take some time or efforts, and it's not a priority as we speak (our backlog is already pretty big). But again, as an Open Source project, we are welcoming contributions!

    To pick a pool: it's up to you to decide, depending on available pool storage capacity, speed. Same for compute and network. It's very very specific to your own needs, there's no universal rules. Host selection for a VM: it's not decided by XO but by XAPI (except if you specifically ask to boot on a host). IIRC, it's a mix of load and memory available, but if you want to dig further, it should be written in the XAPI code somewhere

    @indyj FYI when I ran this test again it worked. this time: I ran it as a "Delta" backup. And then rescanned the removable media. I was then able to restore an individual file from the backup on USB media.

    @garrya Hi, it sounds like you've set up VLAN interfaces correctly on the XCP-ng side, but the switch they are connected to also needs to be aware of VLAN tags to pass them, or else it will only pass untagged traffic as you noticed. You'll need a smart/managed switch with VLAN capability to do so

    We are investigating an elegant solution called RunX. Basically, it might be able to transparently any standard "container stack" (Docker and/or k8s). See https://www.youtube.com/watch?v=9m95hojMtsU There's some work to adapt that to XAPI, but it might be doable. This means XCP-ng could be "container" native while having very good level of isolation with very small VMs (only few MiB overhead).

    5.79.3 / 5.81.0 All of my backups work (now), and speeds range between 5 MB/s to 20 MB/s. Most of my VM's are smaller (zstd helps a lot), though the largest archive is about 80 GB. Also, all of my backups are sequential -- I seem to remember a previous note where somebody had problems with concurrent uploads. My XOCE VM runs with 12 GB, which was the number that "just works" according to some of my earlier problems (and I haven't bothered to chase down or fine tune further).
