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? 1: you need to edit NR_GRANT_FRAMES in linux/include/asm-xen/gnttab.h2: yes, it will eventually be manually configurable with a higher default 'maximum' -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
