Let's see what information is provided. - -First, looking at the ping results from the VM (10.153.107.92) to 10.153.107.80: it works with 0% packet loss, so maybe that's not an issue. But I notice that in the arp -an outputs, on the KVMhost, only 10.153.107.80 is listed with a MAC address on br0. On the VM itself, when it tries to ping, one of the entries shows (10.153.107.61) at incomplete on eth0. That might be a problem because if the ARP entry is incomplete, the VM doesn't know how to reach that IP address. - -Wait, but in Test #3, when pinging from VM to 10.153.107.80, it worked. So maybe the issue isn't with the bridged network itself, but perhaps something else. The user mentioned a workaround using active-backup mode on the bonded device. Maybe the current setup is in another mode that's causing issues. - -Looking at the packages and kernel version: Ubuntu 10.04.02 with qemu-kvm-0.12.3. That's an older version, so perhaps there are known bugs or compatibility issues. The bonding driver might not be handling the modes correctly on this setup. - -Another thought: Maybe the bridge configuration is causing problems. If br0 is set up incorrectly, it could prevent proper communication between VMs and external networks. I should check if the bridge interface is properly configured to allow traffic through. - -Also, looking at the ARP tables, on KVMhost only 10.153.107.80 is listed with a MAC, but from the remote system, it also shows 10.153.107.92 correctly. On the VM, when pinging 10.153.107.80, it sees that address and its MAC on eth0, which seems correct. - -Wait, in Test #3's VM arp -an, there's an entry for 10.153.107.61 with incomplete. Maybe the VM is trying to reach another IP (maybe its own?) but can't resolve it. That could be a separate issue or maybe related to the network setup. - -The user suggested switching to active-backup mode as a workaround, so perhaps the current mode isn't handling failover correctly. If using active-backup, only one link is used at a time, which might resolve issues with how traffic is routed through the bond. - -I should also consider if there are any firewall rules or network policies blocking certain traffic. But since pings are working, maybe it's not a firewall issue. - -To sum up, possible causes could be: -1. Incorrect bonding mode configuration. -2. Bridge setup problems on KVMhost. -3. ARP resolution issues within the VM or host. - -The suggested workaround is to switch to active-backup mode, which might fix the problem if it's related to how traffic is being handled across multiple links in the bond. -</think> - -To resolve the issue with network communication between the virtual machine and the bridged network system, we can try switching the bonding mode to "active-backup." This mode ensures that only one link is used at a time, which might fix any issues related to how traffic is routed through the bond. - -**Step-by-Step Solution:** - -1. **Identify Bonding Configuration File:** - - Locate the bonding configuration file, typically found in `/etc/modprobe.d/bonding.conf` or by checking your distribution's specific location. - -2. **Modify Bonding Mode to Active-Backup:** - - Edit the bonding configuration file to set the default mode to active-backup. - ```bash - alias bond-type bond0=active-backup - ``` - -3. **Reconfigure Network Interfaces:** - - Update your network interface configuration (e.g., `/etc/network/interfaces`) to use the new bonding settings, ensuring that only one link is active at a time. - -4. **Restart Networking Services:** - - After updating configurations, restart the networking services to apply the changes. - ```bash - sudo /etc/init.d/networking restart - ``` - -5. **Test Network Communication:** - - From the VM, attempt to ping the remote bridged network system again to check if communication has been established. - -6. **Verify ARP Tables and Traffic:** - - Check the ARP tables on both the KVM host and the VM to ensure that all necessary IP-MAC mappings are correctly resolved. - ```bash - arp -an - ``` - -7. **Monitor Network Performance:** - - If issues persist, monitor network traffic and bonding status to ensure that the active-backup mode is functioning as expected. - -By switching to the active-backup mode, we can test if this resolves the communication issue, allowing proper network traffic flow between the VM and the external network. \ No newline at end of file |
