output of commands like '%virsh nodedev-list --tree --cap pci'

This check here is done so that the tree printing function prints just
the root nodes of the tree and not every subtree in the tree. If you
remove this check you get something like this most of the times:
virsh # nodedev-list --tree

(the output is severely truncated).
The bug you described is a problem but this solution is not right.
You need to modify the root-finding code for other posibilities.
- vshTreePrint(ctl, vshNodeListLookup, &arrays, num_devices,
- i) < 0)
+ if (vshTreePrint(ctl, vshNodeListLookup,
+ &arrays, num_devices, i) < 0)
ret = false;
}
for (i = 0 ; i < num_devices ; i++) {
NACK to this patch as it breaks the output.
