EPEL 5: Remove checks which fail with ancient qemu.

2012-06-27T15:36:15+00:00

Note that g->qemu_version and g->qemu_devices will both
be empty strings.

launch: Avoid double-close when qemu exits early.

The stdin and stdout of the qemu process are aliased to g->fd:

  g->fd[0] = wfd[1];
  g->fd[1] = rfd[0];

However if the child exits early, then child_cleanup closes g->fd[0],
g->fd[1], AND the code at the cleanup1 label closes wfd[1], rfd[0],
resulting in a double-close.

Avoid this case by setting wfd[1], rfd[0] to -1.  In the cleanup1
label, only close wfd[1], rfd[0] if they are not -1, and add the same
for g->fd[0], g->fd[1].

launch: Ensure errno from test_qemu_cmd is captured and printed.

launch: Set g->sock = -1 to avoid double-close.

This fixes commit ef5c02c6ee72eb8e127115923951777a2c2b8480.

launch: Log errors from close syscall.

launch: Treat /dev/null specially, for old KVM.

2012-06-25T10:20:35+00:00

Old KVM can't add /dev/null readonly.  Treat /dev/null as a special
case.

We also fix a few tests where /dev/null was being used with
format=qcow2.  This was always incorrect behaviour, but qemu appears
to tolerate it.
