The virsh nodedev-list cap --tree command lists all the devices available on the node that are known by libvirt. cap is used to filter the list by capability types, each separated by a comma and cannot be used with --tree. Using the --tree option, puts the output into a tree structure as shown:
   #  virsh nodedev-list --tree
  +- net_lo_00_00_00_00_00_00
  +- net_macvtap0_52_54_00_12_fe_50
  +- net_tun0
  +- net_virbr0_nic_52_54_00_03_7d_cb
  +- pci_0000_00_00_0
  +- pci_0000_00_02_0
  +- pci_0000_00_16_0
