  There's no tool to "merge" old forum or fetch old message. So for few months we'll still have old XO forum then it will be automatically redirected to the XO category here.

  And now, CoreOS is EOL, so it won't help. Maybe there is something doable with the guys behind Flatcar Linux, the fork of CoreOS, to help with support who knows. If you want a GUI for your containers, consider Portainer, it's your best choice, you will have way more features

  3rd party updater/installer aren't supported. You should report your issue first to their GitHub repo. Alternatively, follow our official documentation to install XO: https://xen-orchestra.com/docs/from_the_sources.html If you reproduce the problem, let us know here

  @bberndt said in Create job to migrate several VMs: Tring to create a job, to schedule the migration of several VMs to another host. At the bottom, there are a couple things I don't know. There are two check boxes here for each of these: mapVdisSrs mapVifsNetworks They don't seem to do anything. What are these? Also, what goes in the box Migration Network. The name storage1, or network1 don't work. thanks. Ah! the UUID of the storage Migration network on the destination is what I need, apparently.

  Check host logs to understand why. Maybe those VHD were attached to the control domain or something like that.

  @akurzawa xo-server is not explicitly multi-processed, but it uses async IO calls in Node which should lead to multi-threaded operations. Anyway, we are currently working on reimplementing backups for the proxy and it will eventually lead to using multiple processes. These changes will at the end be merged back to xo-server as well.

  If you create two separated jobs. One for the CR and one for the Rolling snapshot they will not interfere.

  OK the tasks (it been 8 hours since I've checked) are gone, but the VHDs localted on backup server's localstorage remains. QUESTION: How to delete VHDs that are not realted to any vm? I think it will not be deleted automatically. EG. For example - I've deleted "Atlas" VM, but big atlas VHD remains on BackupHost's local storage:

  Hi, It's possible to do it using the UI, simply create a schedule with 7 as Backup retention and 2 as Replication retention.

  Because there's a ton of dependencies, and we try to decouple things, this work takes time. We should be able to run on a more recent version of Node soon, and when it will be the case, our doc will be updated accordingly. That's exactly why we can't support 3rd party installers. Our doc might change and during the interval, if the 3rd party installer isn't following, then it will break.

  @akurzawa said in Extrlemy slow backup speec = about few MB/s: @nikade said in Extrlemy slow backup speec = about few MB/s: Maybe you saw the same thing I did - I also had major issues with backups. Then in the summer of 2019 I upgraded our XOA (Yes, we have the paid version) and everything was going 3-4x times faster. Must have been some major improvement in the XOA code. So maybe some official info that if you have XO from source Your backup speeds will be as low as 3-4 MB/s? Or what? Sorry if I was unclear - XOA is built from the same sources so there is no difference in that aspect. All tho, there was a big performance issue regarding backups which was resolved. I am using XO from sources in my "private" infrastructure and I can assure you there are no "limits" on purpose.

  OK, seems I wasn't trying hard enough. I was trying to mount the tools under the iso list, but when I look further down the list to xc-ng Tools it turns out I can mount the tools from there as long as I do it manually (mount /dev/sr0 /media/blahblah). Installed now, all good.

  Proxies are like XOA (or XO Hub templates): they are pre-configured appliances hosted on xen-orchestra.com, explaining why you can only deploy them from XOA. However, you should be able to use the sources to register a proxy yourself, but we'll document that later (it's still in dev and code is moving fast). Anyway, we'll expose that in the UI, thanks for the feedback

  It's just a missing info in a config file of the appliance. Not a big deal, just surprising to see that now, despite the fact it was there before.
