Not a usual case, will try to fix. In fact, qemu can't recover from host mis configuration. We've already had similar bugs. This needs to be addressed when upstream support need_reset. So lower the propriety and severity. Not 7.2 material. *** This bug has been marked as a duplicate of bug 1151306 *** |
Description of problem: Tried w/o virtio-1, won't hit such issue after delete tap device: (qemu) 2015-07-13T08:32:36.300555Z qemu-kvm: TUNSETVNETLE ioctl() failed: File descriptor in bad state. then try to shutdown guest: Program received signal SIGABRT, Aborted. 0x00007ffff071a5d7 in raise () from /lib64/libc.so.6 Version-Release number of selected component (if applicable): kernel-3.10.0-294.el7.x86_64 qemu-kvm-rhev-2.3.0-9.el7.x86_64 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 shutdown the guest. # shutdown -h now Actual results: qemu core dumped: (gdb) bt #0 0x00007ffff071a5d7 in raise () from /lib64/libc.so.6 #1 0x00007ffff071bcc8 in
