Having the following error trying to convert a live CentOS/RHEL Linux system with VMware Converter?
FAILED: A general system error occurred:
Network error. Host x.x.x.x key can’t be retrieved. (return code 2)
In my case, this happened while converting a RHEL 5.11 server with VMware Converter 6.1.1.
If you went through the following :
– SSH configuration is allowing root to access the system remotely from port 22
– IPtables allow connection on port 22
– You are running Converter version 5.5.1 or greater (there is a known issue with older version that aren’t supporting DSA keys)
Then it might be caused by the “hosts.allow” parameter. Edit the following file :
/etc/hosts.allow
And make sure you have the following entered (usually this file is blank on vanilla systems) :
ALL:ALL
Alternatively, you can restrict the subnet from where the connection come from by entering the following (this example will allow subnet “10.10.5.0/24) :
ALL:LOCAL,10.10.5.
Restart the network service :
service network restart
