That looks ok to me - even if QEMU wants the data provided in
files on disk, libvirt can just create the files on the fly
from the data it has in the <sev> element in the XML file.
Since they're only needed during startup, libvirt can then
easily delete the files the moment QEMU has completed its
startup.
/dev/fd/N filenames could be used for poor man's fd passing, I think.
(/dev/fd is a symlink to the /proc/self/fd directory)
proc(5) has documentation on this.
