Network definitions (xml) are in:
/usr/share/libvirt/networks/
If you edit the network with “virsh net-edit”, any changes you make won't take effect until the network is destroyed and re-started, which unfortunately will cause a all guests to lose network connectivity with the host until their network interfaces are explicitly re-attached.
SOMETIMES the only way is to produce an xml file of the current network with xmldump, destroy-undefine it , modify the xml and then define and start it!
XML config can be reloaded & activated:
virsh net-define /usr/share/libvirt/networks/default.xml
Network default defined from /usr/share/libvirt/networks/default.xml
virsh net-autostart default
Network default marked as autostarted
virsh net-start default
Network default started
Deactivate and then remove a network:
virsh net-destroy <name> virsh net-undefine <name>
