The reason that I didn't drop Virtualbox and tested other hosts is, that I don't know how to get my Windows XP SP3 guest from $ ls -hlG Virt*/winOS/*.vdi -rw------- 1 rocketmouse 28G Apr 20 23:31 VirtualBox VMs/winOS/winOS.vdi to another host. It seems to be hard or perhaps impossible to restore a Win XP from a backup. I at least can't remember that it ever worked for me. If possible I want to restore Win XP from a backup, when migrating to another VM. Any hints how to backup Win XP and restore it on another virtual machine are welcome. Regards, Ralf
