OnApp Cloud version 3.3.0 and earlier
This issue was resolved in OnApp version 3.3.1. Upgrading will eliminate this issue from your cloud.
When a smart server is cold migrated between Hypervisors, the following recipe is executed:
This recipe changes the MAC address of the VM network interfaces to match the ones of the destination hypervisor, and repopulates udev 70-persistent-net.rules so that the interface names remain the same after migration.
When failover happens, only the hypervisor association is changed for the smart server. The network interfaces are not reconfigured, so the smart server is booted up on the new hypervisor with the network configuration from the old one.
