We're taking more of a minimalist approach in kvm_runtest_2: the framework should handle only the things directly related to testing. Configuring and running a DHCP server is and should be beyond the scope of the KVM-Autotest framework. To emulate the old behavior, you can just start the DHCP server yourself locally. If you wish, maybe we can bundle example scripts with the framework that will do this for the user, but they should not be an integral part of the framework in my opinion. > > > > -- > Sudhir Kumar > -- > To unsubscribe from this list: send the line "unsubscribe kvm" in > the body of a message to majord...@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
