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.
