[Xen-users] pciback.hide equivalent boot arg for PVOPS xen/master kernel?
I used to be able to do this with the 2.6.30.3 dom0: pciback.hide=(07:00.0)(07:00.1)(07:00.2)(07:00.3)(14:00.0) Now I get: Unknown boot option `pciback.hide=(07:00.0)(07:00.1)(07:00.2)(07:00.3)(14:00.0)'': ignoring Is there an equivalent boot arg for the PVOPS kernel for this? Where are the docs for what boot args this dom0 kernel supports? -Bruce _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Which, according to the docs:
When building the device model, also known as qemu-dm and qemu-xen,
often automatically downloaded during compilation and found in the
tools/ioemu-dir/ subdirectory of the xen tree, it is important that
the development headers and libraries for libpci are installed.
Otherwise qemu-dm will be built without pass-through support.
If the device model has been compiled without pass-through support,
the following error will show up in xend.log at run-time when
pass-through is attempted.
ERROR (XendDomainInfo:581) Device model didn''t tell the vslots
for PCI device
which means I don''t have the libpci headers installed.
I am getting:
Device model didn''t tell the vslots for PCI device
in the logs, however
I do have the pci-dev headers installed:
#> dpkg -L libpci-dev
/.
/usr
/usr/include
/usr/include/pci
/usr/include/pci/pci.h
/usr/include/pci/header.h
/usr/include/pci/config.h
