vdev pci-dummy
Provide a read-only, inactive PCI device
Synopsis:
vdev pci-dummy options
Options:
- clone host_pci_dev
- Use the specified PCI device as a template for the vdev, and copy the values of the named registers from the host into what the guest will see.
- reg offset/size=value
- Set a specific configuration space register. For example:
sets the configuration space register at offset 0 and size 4 (bytes) tovdev pci-dummy reg 0/4=0xFFFF
0xFFFF
.Permitted sizes are 1, 2, 4 and 8 bytes.
- reg name=value
- Equivalent to the reg offset/size option above, but uses one of the known names (e.g., Vendor_ID). The size is implied by the name, so you don't have to specify it.
For a list of options available to all vdevs, see Common vdev options
at the beginning of this
chapter.
Description:
x86 only. The pci-dummy vdev provides a read-only, inactive PCI device. Such a device may be needed to expose a specific pair of PCI identifiers to help the guest identify a hardware platform.
The following registers are considered: Vendor_ID, Device_ID, Revision_ID, Class_Code[0], Class_Code[1], Class_Code[2], Header_Type, Sub_Vendor_ID, Sub_System_ID.
