Automatically reconnect VMs to bridge (4.2)
Last modified: 2019-06-07 12:51:21 CEST
+++ This bug was initially created as a clone of Bug #49604 +++ +++ This bug was initially created as a clone of Bug #47701 +++ If any UCRV interfaces/* changes, the network is re-configured and restarted. With Qemu/KVM this removes and re-adds the bridge. All VMs will loose their network connection until /usr/lib/univention-virtual-machine-manager-node-kvm/ucs-kvm-reconnect-bridge is manually invoked. UCS should do this automatically: ucr set interfaces/br0/options/65535='post-up /usr/lib/univention-virtual-machine-manager-node-kvm/ucs-kvm-reconnect-bridge -b $IFACE'
