Libguestfs - Jul 2016 - Do we need a rebase bug for RHEL 7.4?

Hi Pino,

$subject -- do we intend to rebase libguestfs, virt-v2v and virt-p2v
in RHEL 7.4?  If yes, we should file the rebase bug soon.

Pros:

 - The RHEL 7.3 package has 151 patches on top of 1.32.6.  Rebasing
   would get almost all those patches.  Not rebasing would mean (at
   predicted growth rate) shipping ~300-400 patches.

 - Backporting patches is currently hard work since the code bases of
   1.32 & 1.33/1.34 have diverged significantly in many areas.

 - We have none of Roman's v2v patches in RHEL 7.3, and it would be
   good to get all of those in 7.4 when we have the luxury of testing
   everything properly.

Cons:

 - Another large rebase.

 - Maybe others, I need to look at the detailed changes in 1.32->1.34.

Rich.

I think this makes sense -- I'd investigate whether it is possible to
reduce the number of patches we carry in RHEL.

virt-p2v converts physical machines to virtual machines.  Boot with a
live CD or over the network (PXE) and turn machines into KVM guests.
