[Xen-users] What does ''non-page-aligned MMIO BAR found'' mean and can I fix it?
I am using Xen 3.3.0 and trying to expose a PCI resource to a domU. I have managed to hide the resource in dom0 by assigning it to pciback. But when I try and start the domU with the pci = [ ''00:12.0'' ] line in the config I get the message: pci: 0000:00:12.0 non-page-aligned MMIO BAR found. (actually I was getting the message about the illegal format character in pciif.py but having corrected that I now get the message above) Can anyone tell me what it means and is there anything I can do about it? The device is a via_rhine Rhine II Ethernet adaptor on a via Epia SN motherboard. Operating system is Debian Etch for both dom0 and domU. Dom0 is using the 2.6.18.8 kernel and Xen itself from a Xen source build. Many thanks Ian No virus found in this outgoing message.
