    I tried this on my lab (with XO 6.9.1), moving the pool master to the other host with xe pool-designate-new-master and then back. XO stayed connected both times and picked up the new master, even though Settings > Servers still showed the old host's address; on the way back it took a minute or two to catch up. I didn't test 6.2.2, and I used the CLI rather than the XO 5 Advanced tab, so my guess that your older version is the difference is only a guess. For the XVA, I'm not aware of release notes for the appliance image itself: it updates itself after import, and the notes that exist are per XO version, in the monthly blog post and the changelog, both linked from https://docs.xen-orchestra.com/getting-started/releases#release-cadence-and-channels . How often the downloadable XVA gets rebuilt I don't know, so the 2025.12 tag may just be the date of the base image, but I'd rather ask than guess.

    I ran into the same problem with DR replicas. Ignoring VMs by tag would solve the problem, but so would excluding the ip address information.

    Hi! We recieved a fix via the support after opening a ticket as suggested. Now the pool metadata backup is running smoothly again. As far as i know 6.9 will become "stable" after 6.10 is released. I'd still suggest a patch for the stable version, unless the new release is a few days. Best wishes Jacob

    @bug-meister Ah. That's cloud-init's support for templating user-data. The issue is that with these templates you only have access to the info available inside the VM itself. No outside data can be used for templating unless it is somehow passed to the VM (inject a file, set xenstore values...)

    @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.

    @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.
