Does anyone know how I can detect if some hardware is actually assigned to some domain (apart from loading the device driver)? lspci does not work (/proc/bus/pci not present).

lspci should Just Work(TM). Are you using a xen0 kernel in that domain? The xenU kernel doesn't have any PCI support.

Cheers, Mark

PS: The doc error: pci_dom0_hide=(xx.xx.x)(yy.yy.y)... should be physdev_dom0_hide=(xx:xx.x)(yy:yy.y)...

Hi,

What does this mean? Having read the FAQ I can guess what it means, but will this be solved eventually?

What version of Xen is this? Looking at ioremap.c I don't see how your build can fail -- __ioremap() is conditional on CONFIG_XEN_PHYSDEV_ACCESS, as is the definition of isa_bus_to_virt in asm-xen/asm-i386/io.h. i.e., if isa_bus_to_virt is not defined, then neither is __ioremap.
