Installation guide

The setup is complete and the guest can now use the PCI device.
15.3. PCI passt hrough wit h virt -inst all
To use PCI passthrough with the virt-install parameter, use the additional --host-device
parameter.
1. Id en t if y t h e PC I device
Identify the PCI device designated for passthrough to the guest. The virsh nodedev-list
command lists all devices attached to the system. The --tree option is useful for identifying
devices attached to the PCI device (for example, disk controllers and USB controllers).
# virsh nodedev-list --tree
For a list of only PCI devices, run the following command:
# virsh nodedev-list | grep pci
Each PCI device is identified by a string in the following format (where 8086 is a variable that
in this case represents Intel equipment, and **** is a four digit hexadecimal code specific to
each device):
pci_8086_****
