The Administration menu gets "VM report (.xlsx)", a workbook for superusers. The VMs sheet has one row per VM on every compute, shut-off ones and those the panel has not registered too: name, state, host, OS and OS family, vCPUs, memory, IP addresses and where they came from, MAC addresses, owners, and whether the panel has registered it. A Coverage sheet says when it was made and what could not be read. The addresses come from the same live reading as the address search, now shared by both. The OS is the guest agent's (libvirt's guest info) or, without one, the libosinfo id a tool such as virt-install wrote into the definition. Link-local IPv6 addresses are left out of the report. Text cells stay text: a VM name starting with "=" is not a formula. openpyxl 3.1.5 writes the workbook.
