I need to recompile kernel, then I will post new logs.

You mean dom0 without XWindow? I don't have XWindow.
Or you mean dom0 without Xen? It works ok.
Or you mean domU without XWindow? I will try.

It starts to show after xm create and stops after xm destroy when I
try to pass-through devices. Without pci=[ <devices>] option there is
no such error.

My vnc shows only white screen. xm console doesn't work. I have no
access to guest.

Without pci option guest works fine and I can connect to it.
