Irgendwie war es notwendig, Open vSwitch (OVS) in R-Virtualisierung plus R-Speicher (RP) zu integrieren, es kann nützlich sein und nicht nur in RP.
Die aktuelle Version des RP zum Zeitpunkt des Artikels war 7.0.13-31 , der Kern in dieser Version ist 3.10.0-1062.12.1.rv7.131.10.1, was der RedHat 7.7-Version entspricht, und die OVS-Version, die mit dem RP-Repository geliefert wird, war 2.0. 0. Die Liste der Funktionen für OVS 2.0.0 finden Sie hier . Die Schlüssel für das RP finden Sie hier .
Ziel war es, VXLAN und den virtuellen Switch als Alternative zu den nativen Bridges für die kvm-qemu- Technologie und libvirt zu konfigurieren . Wenn Sie nacktes OpenSource kvm-qemu verwenden, ist mit OVS alles in Ordnung, aber ich wollte es mit RP versuchen, wo nicht nur nacktes kvm-qemu + libvirt, sondern viele Patches für dieses Bundle vstorage sind .
