Hi, I rechecked the PCI Express spec and this is the desired behavior: When hot-unplugging a switch all devices behind it should be unplugged. Can you please provide guest dmesg? If it is clean (no error messages) we can close the BZ "as designed" Thanks, Marcel (In reply to Marcel Apfelbaum from comment #2) > Hi, > I rechecked the PCI Express spec and this is the desired behavior: > When hot-unplugging a switch all devices behind it should be unplugged. > Can you please provide guest dmesg?

Dmesg of hot-unplug switch
It works as designed and dmesg is clean, all devices behind the switch are disconnected before the switch is going offline. |
