Hi, I have looked at the Xen+IB source tree. I wanted to know if anyone has made a patch that can be applied to existing Xen machines so that IB can be supported? If a patch is not available what is the best way to use the IB source code: Insert into xen source tree and then recompile xen?

This would get you a tree with both sets of features, but might be tedious depending on how far they''ve diverged. Depending on your needs, it might be better to just switch to the Xen+IB tree, or to wait for a release that includes it.

If someone else has an interest and can get to it first, that would be very welcome :).> If a patch is not available what is the best way to use the IB source > code: Insert into xen source tree and then recompile xen?If you''re specifically interested in IB support, for now, you''d be better off just using the IB tree. If you need to use a recent version of Xen for some reason, then you''ll need to do the port to current bits. I''ll ask around and see if anyone has already started on this... thanks, Nivedita _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
