[libvirt] [PATCH v2 0/2] qemu: Fix stalls during live core dump

Qemu uses non-blocking I/O which doesn't play nice with regular file
descriptors. We need to pass a pipe to qemu when dumping core to avoid
stalls in live mode.

Version 2:
- generalize virFileDirectFd a bit more as suggested by Eric

Jiri Denemark (2):
  util: Generalize virFileDirectFd
  qemu: Always use iohelper for dumping domain core
