Re: [libvirt] [PATCH v2 6/8] virFDStream: Add option for delete file after it's opening

This is needed if we want to transfer a temporary file. If the

src/util/iohelper.c: Add new option
* src/lxc/lxc_driver.c, src/qemu/qemu_driver.c,
src/storage/storage_driver.c, src/uml/uml_driver.c,
src/xen/xen_driver.c: Expand existing function calls
I'm not convinced about this commit. We should instead be fixing
iohelper to receive its file by fd inheritance, so that it doesn't have
to open() in the first place. Then you don't need iohelper to worry
about unlink().
