Live Migration Hangs Due to Network Disconnection
Symptom
During the live migration of common and cVMs, if the migration network or the network between migvm VMs is disconnected, the migration process hangs. In this situation, the migration cannot be gracefully stopped; you must manually terminate the VM's QEMU process and the migration process.
Conclusion, Solution, and Benefits
This problem occurs on both common and confidential VMs. To avoid this, ensure that the network remains stable during migration and do not interrupt network connectivity. If this problem has already been triggered, manually terminate the relevant processes and restart the VM.
