Bug Description
[Impact]
* qemu Upstream maintains stable branches to collect considered
to be safe patches - we are at 2.11.1 atm and requested to consider
the most recent 2.11.2
[Test Case]
* Being a stable but full minor release means there is no single good
test to verify. Instead we will pass plenty of regression checks on it
before calling it good.
* The biggest single change is on intel-iommu which we will test
explicitly using manual passthrough tests
[Regression Potential]
* Due to the nature of the change (more than a single fix, affecting
multiple areas of qemu) the chances are higher to hit a regression.
To avoid hitting any in the field I'll run the full qemu regression
suite we have but also would want to leave it longer in proposed and
e.g. ask the Openstack Team to give it a test before releasing.
* In regard to "327d4645 spapr: make pseries-2.11 the default machine
type" and its siblings as well as VSMT which caused trouble in the past
we will need IBM to re-check for PPC if the resulting build is ok
according to their testing as well.
[Other Info]
* Lets make sure we catched all pre-checks:
#1 DONE - Openstack to test the PPA
#2 TBD - IBM to confirm no new issues on ppc/s390x platforms
#3 DONE - Canonical migration and general Virt regression checks
Only once those are all confirmed we will put it into SRU review and
there retest #3 and the passthrough cases.

Since June 2018 QEMU has a more recent stable version (2.11.2) than the one provided in Ubuntu 18.04.1 (2.11.1). This new version comes with a number of bug fixes, which should be incorporated to Ubuntu 18.04.1.

Hi Leonardo,
I'm generally for that, but we are still in a freeze for 18.04.2 being released and even then there is a qemu in the SRU queue that has to clear first.
I'll work on that once these blockers are removed, if there is any extra urgency behind it let me know.
