Hi, <div class="gmail_quote">On Sun, Nov 16, 2008 at 12:56 AM, Ruben Arutyunyan <<a href="mailto:ruben_arutyunyan@shl.ru">ruben_arutyunyan@shl.ru</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Ok, i managed to install the driver. Tried all version for both XP and 2K i could find. If driver install correctly then after more than zero acticity it gives me BSOD with BUGCODE_NDIS_DRIVER. According to MS support pages this means that "An Ethernet driver indicated that it received a packet by using a packet descriptor that the protocol stack is currently using." Anyone seen anything like that? </blockquote></div> I was using the virtio drivers with KVM (with command line or qtemu gui svn), on a Windows guest with virtio drivers. Did you try to launch the guest without virt-manager, ie command line, and test like that? -- Emre
