[libvirt-users] SCM_RIGHTS file error when attaching device?

[steven765 at yahoo.com]

So I just upgraded to 0.8.1-1 and virt-manager 8.4 when i try to attach my network card that's been perfectly fine in the past i now get...

virsh # attach-device gnome /etc/libvirt/qemu/nic.xml
error: Failed to attach device from /etc/libvirt/qemu/nic.xml
error: internal error unable to send TAP file handle: No file descriptor supplied via SCM_RIGHTS

Any thoughts?
