Regression in kernel 3.5 as Dom0 regarding PCI Passthrough?!
Hi!
i notice a serious regression with 3.5 as Dom0 kernel (3.4 was rock
stable):
1st: only the GPU PCI Passthrough works, the PCI USB Controller is not
recognized within the DomU (HVM Win7 64)
Dom0 cmdline is:
ro root=LABEL=dom0root
xen-pciback.hide=(08:00.0)(08:00.1)(00:1d.0)(00:1d.1)(00:1d.2)(00:1d.7)
security=apparmor noirqdebug nouveau.msi=1
Only 8:00.0 and 8:00.1 get passed through without problems, all the USB
Controller IDs are not correctly passed through and get a exclamation
mark within the win7 device manager (...
