Bongiorno Gianluca, I am entering the data in bugzilla right now... Logs: There is a problem, I have not found any log evidence of this export and import, I don't even know which component is actually doing this. For 'foreign' imports like VMware and other *.vmdk producing hypervisors, VDSM seems to be doing the job and leaves logs in /var/log/vdsm/import, describing the format conversion using virt-v2v. For these 'domestic' imports, there is no such log while the imports seem to complete, but with little or no disk data. I am just validating that at least the transfer between farms or the export/import via the deprecated export domain still works. It's quite messy and unintuitive as buttons to detach an export domain don't enable, until you have found a way to put them into maintenance, which for some reason has to be done from the datacenter etc. It's still importing on the target as I write this... Yes, I guess some validation by others would be lovely, just make sure you don't delete any VM you might want back later ;-)
