There is an additional IP address asigned to the virtual server and /etc/network/interfaces configuration file has extra gateway parameter
The issue caused by SolusVM bug #SVM-1091 and will be fixed in future releases
The issue is more a cosmetic one and can be ignored. As a workaround, perform the steps below:
- Connect to the guest virtual server via SSH
- Open /etc/network/interfaces with a text editor and comment extra gateway parameter
