Hey, I am getting this error after using virt-v2v-copy-to-local and trying to run: $ virt-v2v -i libvirtxml rhel7.xml -o local -os /var/tmp -of raw I try to set: export LIBGUESTFS_BACKEND_SETTINGS=virbr0=ovirtmgmt with no success and the file /etc/qemu/bridge.conf contains: allow virbr0 it only worked after creating the bridge, is there other way to import without creating the bridge?
