[Xen-users] PCI passthrough x 3.1 x 3.2.1 x 3.2.2 x 3.3.0
hi there, After a long night playing with various xen versions and kernels I would like to share what I have found and ask for help. My current setup is a xen 3.1. I hide 2 nics and 1 sata controller, and "give" then to a domU firewall and a domU fileserver. Everything seems to work right, except for a segfault on smpd while starting on boot. Now, i´d like to expand my setup and include a mythtv backend with a dvb-s card. Since i saw people having bad experiences with 3.3.0 I did not even bother to try (I should... really). So I got 3.2.2, did a make world && make install, and dom0 booted right. My "main" bridge didnt came up but a ifconfig <bridge> up solved the problem. Earlier domUs seems to work (with the old 3.1 kernel!), and i went to setup the new mythtv domU. First I tried to use the same kernel of the domU, should work (right?), but didnt. So I went to recompile the kernel, removing the PRIVILEGED_GUEST and XEN_BACKEND options. The XEN config part is here[1]. With the new kernel the domU booted but i got a ugly oops when the domU tried to modprobe bttv modules. So, i wen to try 3.2.1, with the very same result. I ended up with my old trusty 3.1... Perhaps the problem is the kernel config, as there was some changes from 3.1 to 3.2. Any hints?
