The kernel's cmdline was set during the initial devstack machine installation. Thus, during second runs, the kernel's cmdline was not updated. This patch extracts append_kernel_cmdline, and configures domU's kernel cmdline every time. As some networking parameters are passed through the kernel cmdline, this patch makes it possible to change the network configuration, even if a cached devstack exists.
