    Hi guys. I am currently testing Continuous Replication as our way, to migrate our vms from one pool, to another. So i set up a test vm and a replication job on the same pool (different sr), since i dont have the new pool yet. Everything worked fine, job is running and creating the replicated vm. But when i want to start the vm, i will get the warning "Forbidden operation Start operation for this vm is blocked." I could klick "force start" but i am afraid, the universe will dissolve. So what is the best practice for my task? Do i have to recreate the vms and attach the cr disks, or is there a way to unblock the cr vm and use it as the new vm? I will have to migrate about 30 vms with 15TB so i obviously dont want to clone the cr vm to a new one. Or do i? Kind regards Milenko

    @florent Thanks for your reply! We have started to migrate thousands of VMs, so disk transfer speed is important for us.. We will also do our detailed tests soon with different threads setting and publish it here. I think threads=1 is a good and logical default, but not efficient. Others might complain if you set it to a higher value. Configuration option would be a real good solution.

    @FagnerMoraes There is now a fix in latest channel now, but you will need to run backup again.

    Good news, this already shipped in XO 6.5.0 (released 2026-05-28), PR #9835. If your XOA is on the latest channel, you've got PATCH /vms/{id} now; on the stable channel, it should land when 6.5.0 gets promoted (stable is on 6.4.1 at the moment). name_description looks like the field you'd write that "what's running here" summary to for your n8n flow, though I haven't tried the new endpoint myself yet. Let us know how it goes.

    Yes. That would be a way of doing so. If you can afford the downtime, you could also use a backup solution (XOA, Alike DR, etc.) to backup the VMs from both hosts, build the pool from scratch using both hosts in a clean state, and then restore back into the new pool (this way gives you a chance to not only start fresh; but, implement any big "lessons learned" or "new ideas" you've got on your list).

    Ping @pdonias IIRC, it's not trivial but this is obviously something we'll working on for XO 6 (there's also limitation in XAPI, because it doesn't tell you what's going on for real behind a task)

    Hello, The DNS names of the master (and nodes also with a pattern) should be configurable for the user indeed. We'll add it in a next version of the recipe. Thanks for the feedback!

    @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: [image: 1581667660068-666ed028-c8e0-4ae7-86f3-1a307f7eee76-image.png]

    Hi, It's possible to do it using the UI, simply create a schedule with 7 as Backup retention and 2 as Replication retention. [image: 1581581696403-fd938a54-8730-4bcf-85c3-7caf2018ac52-image.png]
