Tried the same. OK if done on *ONE* system. I can ping every vm running on this Server.
Now back to my setup. First system: ifconfig eth0.5 0.0.0.0 up brctl addbr vm5 brctl addif vm5 eth0.5 ifconfig vm5 192.168.1.1/24 up Second system: ifconfig eth0.5 0.0.0.0 up brctl addbr vm5 brctl addif vm5 eth0.5 ifconfig vm5 192.168.1.2/24 up On first system: ping 192.168.1.1 -> OK. Works ping 192.168.1.2 -> no output. Only lost pings On second system: ping 192.168.1.2 -> OK. Works. ping 192.168.1.1 -> no output. Only lost pings Both systems are connected. Adding VMs to the vm5-bridge on first system all guests can ping each other. Adding VMs to the vm5-bridge on second system all guests can ping each other. if a guest on first system tries to ping one on second system, the guest on second system is unreachable. If a guest on second system tries to ping one on first system, the guest on first system is unreachable. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to bridge-utils in ubuntu. https://bugs.launchpad.net/bugs/692775 Title: linking two virtual machines does not work -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
