Hi, it seems as if it is not possible to have more than 3 nics per domU right now. If I specify more, I get the usual [...] xen_net: Initialising virtual ethernet driver. #### netfront can't alloc rx grant refs vif: probe of vif-3 failed with error -12 [...] message - see bug #183. It was pointed out to me that it might be possible to adjust this manually in xen/include/xen/grant_table.h, however, setting ORDER_GRANT_FRAMES to 3 to get more pages of grant tables doesn't change anything. Sooo, question #1: how can I alter the code to get more grant tables such that more nics per domU will become available? Question #2: is it planned to make this configurable, e.g. by boot option for dom0?
