Hotplugging of PCI bridges is right now pretty much broken. Coldplugging
and hotplugging will assign wrong primary bus numbers in some scenarios.
I base my knowledge on how this is supposed to work on
http://www.science.unitn.it/~fiorella/guidelinux/tlk/node76.html
I did a couple of tests, building whole hierarchies of bridges, both
hot and coldplugged. "info pci" as well as the Linux guests showed
what I was expecting.
