Hello guys, maybe you can help me with following issue. I have created a little cloud with a host and two worker nodes using opennebula. The setup went successfully until now, I am able to create VM's and move them via normal and live migration. Another (possibly) important information is that I configured my virtual bridge on both worker nodes like this: auto br0 iface br0 inet static address 192.168.0.[2|3] netmask 255.255.255.0 network 192.168.0.0 broadcast 192.168.0.255 #gateway 192.168.0.1 bridge_ports eth0 bridge_stp on bridge_maxwait 0 The command "brctl show" gives me following things back: bridge name??? bridge id??? ??? ??? STP enabled??? interfaces br0??? ??? ??? 8000.003005c34278??? yes??? ??? ??? eth0 ??? ??? ??? ??? ??? ??? ??? ??? ??? ?? ???? ??? ?? vnet0 (<- only appears on node with running VM) virbr0??? ??? ?8000.000000000000??? yes According to thelibvirt wiki this setting is good as is. However, the issue I'm having is that when I create a VM and assign a static IP to it, which looks like e.g. 192.168.0.5, I firstly am able to ping this VM from both worker nodes, and also when I perform a live migration the ping stops for a few seconds (until the nodes realize the new route to this VM) and then starts pinging normally again. However, when I perform a normal migration the ping doesn't recover anymore, but answers repeatedly with: Destination Host Unreachable Do you know what could be the problem? Where is the difference between a normal and live migration and how can the ping after live migrating still work, but after a normal migration not? Thanks a lot!
