This occurs mainly when the following is performed:
- VM is running fine, and in Bridged networking mode connected to the LAN network interface. This interface is connected to a wireless router
 
- The VM state is saved
 
- Host is put to sleep
 
- Wireless router is unplugged
 
- Host is woken up
 
- A different network device, in this case a network hub is plugged into the LAN
 
- The VM is started again, and the error appears
 
The workaround is to delete the savestate and start the VM again.
