Migration Suspended Due to Live Migration Network Disconnection

Symptom

During live migration of common and confidential VMs, if the migration network or the network between migvm VMs is disconnected, the migration process is suspended. In this situation, the migration cannot be gracefully stopped; you must manually terminate the VM's QEMU process and the migration process.

Conclusion and Solution

This problem occurs on both common and confidential VMs. Ensure that the network remains stable during migration and do not interrupt network connectivity. If this problem has already been triggered, stop the relevant processes and restart the VM.
