Hi, I managed to resolve this issue. Long story short : - take configuration details from hosts about disks (especially if direct disks are being used, commands like multipath -ll, lsblk, blkid...) - take a xml dump from all running VM's - install new standalone engine - add existing hosts to new image (running machines were detected with prefix "external" - configure logical networks after checking hosts network adapters - if direct disks exists in your configuration, create virtual disks for them by using xml dump files and info from hosts - shutdown running vm's (all with prefix "external") - shutdown all kvm hosts and left only one kvm host running (to prevent sanlock) - import existing storage domain from running host - use VM import tab in Storage domain to view vm's available for import - delete machines with prefix "external" because import detect machines with same VM ID - run import VM's from storage domain, one by one ... and that's it, after import run the machines ***If there are no VM's listed in VM import tab after adding storage domain, than you need to import disks from Disk import tab in storage domain, and then manually create virtual machines with information from xml dump files (to be able to configure disks,networks,cpu,ram ... like it was originally configured). After creating VM's you should be able to run them.*** Maybe it can help someone. Best regards, Igor
