The userspace libvirt (qemu:///session) cannot add interfaces to a bridge device.
This won't get fixed unless virt-manager provides a helper script to run something like "sudo brcrtl addif br0 tap0". Or just put "You need root privileges to use bridged interfaces with virt-manager" into the documentation and be done with it. -- Error starting domain: virDomainCreate() failed Failed to add tap interface 'vnet%d' to bridge 'br0' : Permission denied https://bugs.launchpad.net/bugs/247677 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
