    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...)

    Hi, FreeBSD install was already documented officially: https://xen-orchestra.com/docs/installation.html#freebsd You could have test to use HTTP instead of HTTPS to see if perfs are improved New XO backup code will come in few releases that will speed up things Quiesce snapshot: it's not needed for Linux VMs because of the disk driver automatically handling this.

    Question about XO snapshot location

    Yes indeed, in CR, you'll send a copy of the disk toward a destination SR. But still, the snapshot is made on the same storage. However, I get your point, and I think in theory, it could be doable with some heavy changes in the storage stack (to have a snapshot located "elsewhere"). However, for each read in the VHD chain, you'll have to read on multiple storage at once, which can be complicated technically speaking (especially if they are shared)

    Kubernetes Recipe - Basic setup not working

    It seems that Debian Buster has some problems with Kubernetes. While this base setup is working, one should also assure that every tool uses the legacy iptables. If not, pod's will not be able to reach the kubernetes api... And then... failure all over! So we also need: update-alternatives --set iptables /usr/sbin/iptables-legacy update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy update-alternatives --set arptables /usr/sbin/arptables-legacy update-alternatives --set ebtables /usr/sbin/ebtables-legacy ```

    Hi, Audit logs aren't in the same location than the xo-server logs. To get Audit logs you can use this command xo-cli audit.getRecords which returns an array of records. xo-cli audit.getRecords This command has an option ndjson, which allows you to export logs in a ndjson format. xo-cli audit.getRecords ndjson="json:true" @=<outputPath>

    @Rocky most like a connection issue, but since you already restarted I think the logs are already gone. If it was a one-off I wouldn't worry about it (but do make sure that the backup is actually working, may be a good idea to do another full backup).

    XO debian 10 cloud ready VM template (cloud-init)

    I was able to find the reason XO is not working with cloud-init. XO attaches iso with the cloud-config data as additional disk xvdb and it does not work. But if you provide it as a cd? It will. That is why - as for now you will need to create your own iso and attach it as a cd-rom. You do that this way: Get your files ready (meta-data network-config user-data). My examples below: metadata: instance-id: local-nocloud local-hostname: myhost.example.com network-config: network: version: 1 config: - type: physical name: eth0 subnets: - type: static address: 10.0.0.5/24 gateway: 10.0.0.254 - type: nameserver address: - 8.8.8.8 - 8.8.4.4 search: - example.com - type: physical name: eth1 subnets: - type: static address: 192.168.0.5/24 user-data: #cloud-config ### RUN CMD runcmd: - /usr/bin/apt -y install mc - /usr/bin/date >> /root/testfile # set system default user system_info: default_user: name: testuser gecos: Default Cloud User # password auth - comment out if not using passwords password: testpassword ssh_pwauth: true chpasswd: { expire: false } # do some package management #package_update: true packages: - iptraf - mtr - screen - net-tools - atop Generate iso genisoimage -output myiso.iso -volid cidata -joliet -rock user-data meta-data network-config Upload iso to XO home -> storage -> iso's -> disks -> new disk Prepare VM/template Install Debian 10.6 with xo-tools install cloud-init and cloud-initramfs-growroot remove all network configuration leave just "allow-hotplug ethxxx" (network config will be added in /etc/network/interfaces/50-cloud-init. It will not overwrite yours) shutdown the machine and create the template if you want or just restart VM. DO NOT LET IT BOOT! - keep it in grub. attach your iso let it run It will do whatever you need on the machine.

    @olivierlambert said in Detached Backups: You can do that already if you like (combined rolling snap and delta backup). But what's the point? Oh, wow. You can combine backup methods in the same job (as long as they are compatible methods (i.e. Delta and CR). This is cool. I currently have separate jobs for my deltas and CRs. I'll need to make time to make the changes, but this will simply things greatly. I'll even throw in a few extra snapshots to retain. So, yea, this is pretty much what I was thinking of. I didn't realize it was there. Why would I need this? Well, when my WSUS installed the Xen drivers on all my Windows VMs, I went a day before realizing what happened. A snapshot would have been sufficient, if I had one from the day before. Instead, I restored the backup which broke the chain. @olivierlambert said in Detached Backups: edit: about your previous question, restoring without breaking the chain. That might be possible. In theory, after restore, we should take a snapshot before booting the backup and then re-link the restored VM to the backup folders. It's doable (renaming some folders correctly) but I'm not sure this will be very useful. I'll look into this when I get some time. Thanks.
