    Good afternoon, I am currently working in a lab environment using XO from sources. I am running into an issue with XOA when it comes to backups, I have tried this with S3 backend to a local S3 with seaweedfs. All my other backups are working on other platforms but, this one for XOA is not working. I have tried delta backups and just regular full backups. If I do one full backup, it works for just the one iteration and then after, I get the same error in the photo posted. I have to delete the backup, delete the job and remake everything. If I need to provide more, please let me know. Current XO: commit 69080 Backend Storage: seaweedfs S3 4.03 How many host effected: 1 When did this start: 12/18/2025 V/r A loyal user.

    Hi @xo-g , We don't use any specific order to pick the VMs to backup.

    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.

    @olivierlambert That socket issue was not what was causing the problem, I went through setting by setting and if I choose 2GB of memory for a VM I get constant reboots when using XOA. I was able to repeat the issue with a number of OSs not just RHEL 8 (and variants). I havent went through and compared the differences between XOA and XenCenter yet.

    @s-pam said in Multiple remotes in a backup - how is retention calculated: OK Great. So if I set retention to 10, it would keep 10 copies on each remote? Yes. it will keep 10 copies on each remote.

    In theory, Xen Orchestra got a protection against this issue (see https://xen-orchestra.com/docs/backup_troubleshooting.html#vdi-chain-protection ) So you have to find what's causing a long chain outside XO. You can check in XO, in the Advanced tab of the SR view, if there's VDI to coalesce. Or maybe very long chain for other reasons, there's a tool we made called xapi-explore-sr.

    Use CR instead of DR then, it will send only the diff to the other host, so it will be faster.
