Then you just have to make sure the password is the same as the password KVM autotest expects, which is 123456, as stated on the config file guest-os.cfg. Also, another thing that would be reasonable to expect is that sshd is up and listening on port 22 and firewall allow access to that service. It seems you are using RHEL, so SELinux might play some pranks on you, although it is hard to anticipate all things that could go wrong. but well, if you check the things I stated on the first sentence, I believe it will work. _______________________________________________ Autotest mailing list [email protected] http://test.kernel.org/cgi-bin/mailman/listinfo/autotest
