I believe you're hitting BZ 696877, so I'm closing this as a duplicate. Please feel free to reopen if that turns out not to be the case. *** This bug has been marked as a duplicate of bug 696877 *** Could you provide guest.xml & hostdev.xml files? what was the guest? (linux, win, what version of the guest, e.g., rhel5, winxp-32, etc.) (In reply to comment #3) > Could you provide guest.xml & hostdev.xml files? > what was the guest? (linux, win, what version of the guest, e.g., rhel5, > winxp-32, etc.) The guest I am using is RHEL 6.1.

Description of problem: When using a model of separate network and guest XML's (using forward mode) to start a guest on RHEL 6.2, a simple test of pci-hotplug, pci-unplug and pci-hotplug again of PCI device fails.
