libvirt users - Jun 2010 - SCM_RIGHTS file error when attaching device?

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?

This is a flaw in QEMU fixed upstream

commit e53f27b9d9df73461308618151fa6e6392aebd85

    stash away SCM_RIGHTS fd until a getfd command arrives
    
    If there is already a fd in s->msgfd before recvmsg it is
    closed by parts that this patch does not touch.  So, only
    one descriptor can be "leaked" by attaching it to a command
    other than getfd.
