Upgrading the host

Hello-- I'm planning on upgrading the OS on my host machine by doing manual re-installation, which will trigger an upgrade of libvirt from 1.1.3 to 6.1.0.  Hardware, storage volumes & paths, etc., will be the same after upgrade. I was going to redefine & start everything from .xml files, starting with the network     virsh net-define <network XML>     virsh net-autostart <network>     virsh net-start <network> and following with all the guests     virsh define <domain XML>     virsh autostart <domain>     virsh start <domain> I have the following questions: 1. Do I need to generate XML dumps manually, or is it ok to use the ones from host's /etc/libvirt? 2. Do I need to define & start storage pools & volumes explicitly, or will they be picked up from domain definitions? 3. Anything else I should worry about or prepare ahead? --Marcin
