Description of problem: Libvirt crash after defining/editing macvtap network pool with unsupported <address> elements Version-Release number of selected component (if applicable): libvirt-0.10.2-44.el6.x86_64 qemu-kvm-rhev-0.12.1.2-2.428.el6.x86_64 kernel-2.6.32-468.el6.x86_64 How reproducible: 100% Steps to Reproduce: [root@sriov2 jiahu]# cat pci.xml <network> <name>passthrough_001</name> <forward mode='passthrough'> <address type='pci' domain='0' bus='0x11' slot='0x10' function='0x1'/> </forward> </network> [root@sriov2 jiahu]# virsh net-define pci.xml error: Failed to define network from pci.xml error: End of file while reading data: Input/output error error: One or more references were leaked after disconnect from the hypervisor error: Failed to reconnect to the hypervisor Or added below line to an existing network tiwice. <address type='pci' domain='0' bus='0x11' slot='0x10' function='0x1'/> [root@sriov2 jiahu]# virsh net-edit passthrough error: End of file while reading data: Input/output error Failed. Try again? [y,n,f,?]: error: internal error client socket is closed error: One or more references were leaked after disconnect from the hypervisor error: Failed to reconnect to the hypervisor Actual results: As shown above steps, libvirtd crashed. Also can reproduce it on libvirt-0.10.2-43.el6.x86_64 Expected results: No crash Additional info: Program received signal SIGSEGV, Segmentation fault.
