Troubleshooting
Problem
QRadar® virtual appliances with dynamic MAC address assignation might become inaccessible when using SSH after a reboot or network service restart. When the problem occurs, the error "Device xxx has different MAC address than expected" appears.
Symptom
When accessing the QRadar host by using SSH, it reports "No route to host".
ssh: connect to host <QRadar IP ADDRESS> port 22: No route to host
The Console's user-interface does not load and reports timeout.
