We''re running Plan 9 in xen3.0.3, and it is working pretty well (Thanks to all!). And boy, is it faster than Qemu. I am enjoying it, esp. now that ACPI works on my laptop under dom0. One thing I am seeing: at some point, usually caused if I run vncviewer in Plan 9, I stop getting receive interrupts. It seems as though a large amount of data pumps it way to Plan 9 in the form of images, and we''re not keeping up somehow. I can still send packets, and I can get interrupts on that activity; what I don''t see is receive interrupts. It''s been (literally) 3 years since I debugged at this level, and I am rusty; any hints about how to hunt this bug down and kill it are most welcome. Or just hings on what we might have wrong in this port that could cause this behaviour. thanks again ron _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

I''d print ring indexes in netback and work out what condition is causing it to discard packets that you should be receiving. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

We caught it yesterday, it was a race condition in the new driver -- we think :-) -- at least our bug fixes seem to resolve the problem. Now I can move on to pcifront :-) I''ve gotta get a dual-core laptop as well, it would be nice. ron _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
