Description of problem: Version-Release number of selected component (if applicable): libvirt-0.3.3-2.fc8 kernel-2.6.24-0.39.rc3.git1.fc9 How reproducible: Always Steps to Reproduce: # libvirtd --verbose libvir: QEMU error : failed to bring the bridge 'virbr0' up : Invalid argument Failed to autostart network 'default': failed to bring the bridge 'virbr0' up : Invalid argument Additional info: It appears to be specific to recent upstream kernels. The EINVAL is being returned via 117 ioctl(7, SIOCSIFADDR, 0x7fff4e862d60) = 0 5117 ioctl(7, SIOCSIFNETMASK, 0x7fff4e862d60) = 0 5117 ioctl(7, SIOCGIFFLAGS, {ifr_name="virbr0", ifr_flags=IFF_BROADCAST|IFF_MULTICAST}) = 0 5117 ioctl(7, SIOCSIFFLAGS, 0x7fff4e862d70) = -1 EINVAL (Invalid argument) 5117 write(2, "libvir: QEMU error : failed to b"..., 79) = 79 Which corresponds to: brSetInterfaceUp() in libvirt and dev_change_flags() in the kernel, if ((old_flags ^ flags) & IFF_UP) { /* Bit is different ? */ ret = ((old_flags & IFF_UP) ? dev_close : dev_open)(dev); where it seems that dev_open() is failing.
