netcat-openbsd is an optional dependency (needed if you
want to connect from a remote host using virt-manager).
Other optional dependencies include avahi, xen, audit, glusterfs,
-and numactl.
+numactl, open-iscsi and libiscsi.
As of the 4.5.0 version, you may have to remove any previously
installed versions of libvirt before this will build.
+
+Note also that sometimes, in consequence of a major-version upgrade,
+you might discover that the libvirt configuration is in an inconsistent
+state (machine networking broken and so on) and when this happens you
+might want to consider starting from a clean state. To do this:
+- backup the existing vms files and their configurations too (with
+ "virsh dumpxml $name > ${name}.xml)
+- remove libvirt
+- delete all the system directories (/var/lib/libvirt, /var/log/libvirt,
+ /etc/libvirt)
+- install the new libvirt package, logout and login again (might help)
+ and start the daemon
+- recreate your configurations (network and so on)
+- reimport the vms xml backups (with "virsh define ${name}.xml")
