Re: [libvirt] PATCH: Add --tree flag to virsh nodedev-list

The virsh noddev-list command is used to display node devices. It just prints out their names in a flat list. When detaching devices for purposes of PCI passthrough though, it is important to understand what devices are children of the PCI device about to be detached. It is tedious to find this out, the user having to run virsh nodedev-dumpxml and look at the parent field.

This patch adds a new '--tree' flag to the nodedev-list command, allowing a prettier format to be used # virsh -c qemu:///system nodedev-list --tree computer | +-pci_8086_2448 | | | +-pci_104c_ac56
