[Starlingx-discuss] Qemu 3.0.0 is ready for your consideration

[Jim Somerville]

Hi Dean,

Like with libvirt, I de-squashed all of the patches (around 100 of them) 
and they are on the end.  Note that they consist of 3 parts, namely any 
fixes I had to further bring in from upstream (1 in this case), followed 
by the CentOS patches against qemu that we normally bring forward, 
followed by STX specific patches.

The CentOS patches against qemu are good candidates to scrutinize for 
potentially dropping in the future as part of a non-rebasing exercise. 
My approach was to limit chaos in this upstream rebasing exercise by not 
dropping any patches unless made obsolete by the rebasing itself.  It's 
hard enough to debug this complex stuff without adding more 
uncertainties to it.

Extensive testing was done using first our regular sanity test suite, 
followed by our much larger nova regression test suite.  Unexpected 
failures were found and fixed.

The update to 3.0.0 consists of two parts, a pull request for the 
stx-qemu repo, and the piece in stx-integ which deals with the 
compilation.  Like last time with libvirt, we have to commit these two 
parts at the same time.

The new qemu is here, and I will push a new branch and issue a pull 
request to it once I'm done dealing with feedback.

The stx-integ part for review is here:

I also cc'ed anybody who I think is a directly interested party rather 
than just relying on the discussion list.
