    @Cygace Someone from the community may jump in and help troubleshoot this. The best approach would be to not modify the Dom0 installation by installing Zabbix via a community post, as you're customizing the installation. The vates team and XCP-ng specifically need to include these packages to ensure you're able to get support. Best of luck

    This is the date get from XAPI. If it was migrated from another host, you have the first time it was visible for this XAPI.

    I thought I did that. Oh I see whats happening. My cold moves are freaking out. The first time, I restarted the toolstack for the server I was working on the # of tasks dropped by 50% or so. as soon as I tried my cold move of a VM again, im up to 50-60 tasks again. Going from Xen 7.1 to XCP 7.6. and a Xeon 2630 V3 to a 2620 V0. Which I know is a bad idea, hence the cold move.

    You have a transparent proxy, it does not hide its identity, so web resources see that the request is not coming directly from the user but from the proxy. In addition, the real IP address is also visible, so there is no anonymity. Usually, educational institutions use this type of server to filter incoming and outgoing content and cache information. It's better to use thailand proxy, which will encrypt you from the inside.

    Not sure yet if it has to do with me deleting one template to try... However, the duplicated templates have disappear after the update of XOA to 5.74.3! Maybe a restart of the service would have achieved the same!? At the end, it seems to come from XOA rather than the pool. I suggest to remove and add the master from the server settings to see if this does not clean up something in the cache/DB on XOA...

    @florent Yes, thanks! We have very limited control over rsync at our end (as it's running within a Synoloy NAS) - I think we probably have to just live with large transfers for now - whilst looking at spit files / VHD's as the way to go in the future. Thanks again!

    @AtaxyaNetwork Thanks for your guidance. I can create a lightweight Debian VM with an NFS share for the ISOs. But even so it is strange that the drive is not known by the XO. Maybe other people can comment on this later.

    @furyflash777 I'm assuming you're on Ubuntu? Indeed as Olivier said this is tested on Debian and doesn't cause issues, but it seems on the newer Ubuntu versions with cloud-init, the new Netplan based network manager and how it interacts with cloud-init breaks/gets wiped if no cloud-init drive is found. Yet another cloud-init bug to track down

    Hi, "It depends" is the answer here Depends on: the number of concurrent users on your XO instance the size/frequency/number of backup jobs you have the number of hosts and VMs managed by XO Frankly, for a small setup (less than 4/5 hosts) with one users and few backup jobs, the default 2vCPU/2GiB RAM is enough. Especially since we improved various process to happen in a dedicated worker
