    1717 * When the kernel module doesn't load, i.e. you get an '''"Error inserting vboxdrv: Invalid argument",''' check (as root) the output of the "dmesg" command. In 90% of all cases, this is a problem with Linux 2.6.19 and higher, and the message will be: "NMI watchdog active -- refused to load the kernel module! Please disable the NMI watchdog by specifying 'nmi_watchdog=0' at kernel command line." Add this option to your grub configuration, reboot, and the module should load.

In that case do the following:

    45  * There is no networking in Windows Vista guests initially because, unfortunately, with Vista, Microsoft dropped driver support for the virtual AMD PCnet card that we are providing. See the "Troubleshooting" -> "Windows guests" in the updated [wiki:"Downloads" User Manual] for a solution.
