Yep, this is perfect candidate for a TCK test case. Take the 210-nic-hotplug.t test case, and make it attempt to plug+unplug a NIC 35 times in a row. This should test this particular bug, and also validate that PCI addresses are being reused correctly (there're only 31 pci slots that can be used at any 1 time) Daniel -- |: Red Hat, Engineering, London -o- http://people.redhat.com/berrange/ :| |: http://libvirt.org -o- http://virt-manager.org -o- http://deltacloud.org :| |: http://autobuild.org -o- http://search.cpan.org/~danberr/ :| |: GnuPG: 7D3B9505 -o- F3C9 553F A1DA 4AC2 5648 23C1 B3DF F742 7D3B 9505 :| -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
