    @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

    @S-Pam said Isn't any SQL server crash safe? I.e. they should handle a system power-loss and gracefully recover (journals). A filesystem snapshot is equivalent of a power loss. You need to configure your databases accordingly. Most of maria/mysql have enabled innodb doublewrite enabled by default: https://dev.mysql.com/doc/refman/5.7/en/innodb-doublewrite-buffer.html But just in case of Active Directory... I really really want to have consistent snapshot/backups

    Add Host to pool, is this non-destructive to local VM's?

    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).

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.
