Richard W.M. Jones 8190ec8540 Include a few experimental non-upstream patches
These two patches fix potential issues.  Best to get them tested over
Christmas and New Year.

    v2v: Swap over the output and conversion stages

    In old virt-v2v, we did (approximately, since the steps were not as
    clear):

      Input -> Convert -> Output -> Copy -> Finalize

    After modularizing virt-v2v we changed this to:

      Input -> Output -> Convert -> Copy -> Finalize

    However this has a (sort of) problem.  For -o rhv-upload when we start
    the nbdkit rhv-upload-plugin machinery, it obtains a time-limited
    ticket from imageio.  This ticket could expire if the conversion step
    takes longer than a certain time (60 seconds by default, may be
    increased in a future version of oVirt).

    I believe this is really a problem in imageio or that the
    rhv-upload-plugin should really renew this ticket automatically, but
    it does not, instead failing.  (The ticket *is* renewed automatically
    whenever a request is sent to imageio, but in this case no requests
    are being sent).

    Anyway the easiest thing is to switch the ordering back to how it was
    in old virt-v2v (at top).  It doesn't make a difference for any other
    output modes.

and:

    v2v: Remove nbdcopy --request-size=4M flag

    This was added when we were setting the cow-block-size to 1M.  However
    since commit 351d61f768 ("input: -it vddk: Reduce cow-block-size to 4K")
    we stopped doing that so this is no longer needed.

Subject: [PATCH] RHEL: v2v: Select correct qemu binary for -o qemu mode
(RHBZ#1147313).
RHEL does not have qemu-system-x86_64 (etc), and in addition the
qemu binary is located in /usr/libexec. Encode the path to this
binary directly in the script.
Note that we don't support people running qemu directly like this.
It's just for quick testing of converted VMs, and to help us with
support cases.
