    That's a very good question, let me ask internally. Ping @pdonias he might know the answer

    @Pilow Yeah, true. Also during my CBT-enabled-backups tests live migrations did trigger the fallback to a full from time to time aswell (VM residing on a different host during backup run compared to last backup run). But I did those tests ~6 months ago so maybe some fixes have been applied in that regard. You are right, in a thick provision SR / block based scenario taking a snapshot would result in the same size of base VHD being allocated again for the purpose of snapshotting... not really practical. I really hope that CBT receives some more love as we plan to move our storage to a vSAN cluster and intend to use iSCSI instead of NFS by that time so using CBT would also be our best bet then... CBT also reduces the load on the SR (as in I/O) as it removes the need to constantly coalesce disks during backup job re-creation / deletion of snapshots. @acebmxer Interesting during my tests CBT was not really stable as in backups falling back to full quite often. I recall reading somewhere in the documentation that CBT has some quirks so it seems to be a known issue.

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    Yesterday I updated to the latest sources and my backup ran successfully, so it appears that this issue is resolved. @carlosfrederico You'll need to switch back to the master branch before your normal update routine will work.

    @olivierlambert FYI turned out to be a networking issue that had nothing to do with the server itself. I'm still getting to the bottom of what exactly the cause was, and will update here once I do just in case someone else runs into this. Thanks again. And thanks for the awesome software. ! -Rob

    No, there's no need to upgrade VM tools when you upgrade the host. You can keep old tools, it will work fine.

    @dan2462 Did you get a resolution to your VDI issue? I have a similar problem as it seems hosts are locking up the VDI's on my shared iscsi storage and if they are shutdown and I try to boot them on an alternate host, I get the VDI not available error.

    You can have one job with 2 remotes. Or a job with backup and DR at the same time.

    SAML, automatic user generation

    @mrbaz Thanks for the detailed feedback! If XO had a way of pulling the user's group information and only allowing those in a certain group to have authorization to XO to have their accounts automatically generated, that would work too. That wouldn't be trivial to implement with our current plugin system. But as you said, a user that logs into XO isn't able to do anything without granting them permissions first. Also, if this is still a concern for you, you can disable user auto-generation in xo-server configuration by adding this line: createUserOnFirstSignin = false However, you'd then have to create the users manually before they can log in. the issue still stands that I can't put a user into a group or assign ACLs until after they have signed in for the first time. I agree but I'm not sure what a good solution to this would be. If we add an option to import all the users at once, it could mean importing a lot of users for some companies, even if many of those users would never actually log in later.

    @olivierlambert said in un-zstd .xva files exported with XOA?: Hi! Again, before starting to talk about technical solution, can you explain the use case? If you have zstd installed on your machine, yes. It's a tar with compression (gzip or zstd). But then it won't be trivial to assemble VM data (but you can exctract metadata easily!) I didn't really mean disassemble the .xva, but rather create an uncompressed .xva that has broader support/portability. The zstd command line tool seems to be able to uncompress it just fine. Thanks.

    Hey there! It's a good thing to start by reading our doc. If you enter "Password" in the search field, you would have find: https://xen-orchestra.com/docs/troubleshooting.html#recover-web-login-password As you are using Xen Orchestra into production, may I suggest to go for XOA with pro support at some point?

    @olivierlambert Maybe. Ive created a support ticket for now. Hopefully you can see if the problem is a configuration mistake on our end or a problem in XO. Thanks.

    You can't, indeed, live migrate a VM from Intel to AMD (or vice-versa), for obvious reason (the VM will try to call Intel specific instructions after migrating on an AMD CPU, the result would be… a crash!) We had a similar migration ourselves (in our own prod), from Intel to AMD. And we decided to use Continuous Replication to make a first "backup" on destination (the full) while the original VMs were running (no service interruption). Then, we shut down the VMs, make another round of replication (delta, very fast) and then we booted on destination.
