BASIC OPERATIONS\\
  virsh shutdown guest1 --mode acpi
  virsh destroy guest1
  virsh undefine guest1
  virsh suspend guest1

  virsh reset guest1

  virsh managedsave guest1 --running # to save running state.
  virsh start guest1      # starts it from the point it was saved

\\
Hypervisor level network definitions (xml) are in:
  /usr/share/libvirt/networks/
Rest of them (virtual networks) are in:
  /var/lib/libvirt/dnsmasq
\\
**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>
\\
For the libvirt dhcp ''virsh net-dhcp-leases ${net}''
   for net in $(virsh net-list --name); do virsh net-dhcp-leases ${net}; done
