*** This bug has been marked as a duplicate of bug 1151306 *** Seems this bz is against qemu-kvm component. Bz1151306 is against qemu-kvm-rhev component. Means that we do not plan to fix this issue against qemu-kvm build? Thanks. Best Regards, Junyi (In reply to juzhang from comment #3) > Seems this bz is against qemu-kvm component.

Description of problem: Launch win2008r2 guest enable multiqueue;Delete the tap interface in host;then reboot guest,qemu core dumped. If disable multiqueue; no this issue Version-Release number of selected component (if applicable): host:(AMD) 3.10.0-319.el7.x86_64 qemu-kvm-1.5.3-104.el7.x86_64 guest: win2008r2 How reproducible: 100% Steps to Reproduce: 1.Boot guest, cli refer to the additional info. 2..Delete the corresponding tap interface in host: # ip link delete tap0 3..Try to reboot the guest.
