Hi Michael,
yeah manually enabling it is a workaround, but to let the maintainer scrtipts do it right on install is still the preferred way to do it.
But all looks good on the way to get it into artful, regression tests, dep8 tests, ...
Might just be blocked a bit by the release week freeze, but other than that the right fix is on its way.

Title:
qemu-kvm doesnt restart after node reboot
Status in Ubuntu Cloud Archive:
New
Status in qemu package in Ubuntu:
In Progress
Status in qemu source package in Zesty:
Confirmed
Status in qemu source package in Artful:
In Progress
Bug description:
[Impact]
* Since the Zesty Merge the qemu-kvm service fails to be active by
default.
* It is a non required but rather useful helper, so it should be fixed to
be enabled as it was pre zesty due to systemd-generators taking it from
sysv scripts back then.
[Test Case]
* Install qemu-system-common
* Then check
$ systemctl status qemu-kvm
* This should be active (exited) but is currently disabled
[Regression Potential]
* If this script causes any issue for someone (not known so far) and he
was running on zesty a while it will on the SRU update be enabled and
trigger these issues. Yet this is a generic argument and if that would
be a blocker no services would be allowed to be enabled. I verified
that if masked the service stays off as it should.
[Other Info]
* IMO this issue qualified for (2) the following of the Final Freeze:
2) Bug fixes that would be suitable for post-release SRUs, which we
may choose to accept, reject, or shunt to -updates for 0-day SRUs
on a case-by-base basis.
