When I install Eucalyptus cloud using the faststart method, I see that installation failed. When I check the log file later, I encounter the following errors.
The error message is:
Invalid gateway due to subnet/netmask for subnet...
Which means that the gateway value you entered is not in the subnet that you specified.
For example if you entered:
subnet: 10.111.0.0
netmask: 255.255.0.0
Then the gateway could be '10.111.0.1' but could not be '192.168.0.1' as that is not within the subnet.
