    @olivierlambert Oh okay, thanks for responding. So I turned off SYNC and COMPRESSION on the dataset and retested (by suspending 11 VMs), I immediately noticed a whopping performance improvement (essentially sustained wire speeds AND 50% faster completion time*) : Roughly 984 Mb/s sustained WRITE speeds (during VM suspension) Roughly 984 Mb/s sustained READ speeds (during VM resumption) Transfer time for both READ and WRITE is about 20 minutes (down from 40-45 mins) [image: 1753218219233-screenshot-2025-07-22-170106.png] Gonna retest with SYNC disabled and COMPRESSION re-enabled and see if it degrades performance; standby for another report.

    @DustinB said in Backups started to fail again (overall status: failure, but both snapshot and transfer returns success): @peo said in Backups started to fail again (overall status: failure, but both snapshot and transfer returns success): @olivierlambert Thanks, will update every machine and XO involved in the backup process, and possibly even the individual machines that fails. First failure on vm-cleanup was 15 July, that's a few days before I patched the hosts (as a part of troubleshooting and preventing further failures). Still these backups will (probably) be fully restorable (as I have tested out with the always-failing Docker vm) So you patch your host, but not the administrative tools for the hosts? Seems a little cart before the horse there, no? That's a fault-finding procedure: do not patch everything at once (but now I did, after finding out that patching the hosts did not solve the problem)

    @duxepu Ok, this is weird, I'm not able to reproduce that and I don't see how it's possible. Could you check a few things? from an admin point of view, at the bottom of the VM's advanced tab, please check that the user has Admin ACLs on the VM from the user's point of view, when you're on the snapshots tab, open the browser console (press F12 > Console tab) and check if there are any errors do you have this issue with all the users of all your Self Service groups or is it more specific? Thanks!

    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.

    un-zstd .xva files exported with XOA?

    @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.
