Bug Description
=======
Impact: hugepages not available for use by kvm
Fix: systemd uses the sysvinit qemu-kvm job rather than the more uptodate upstart job. To keep those in sync, the fix switches to a single common script which is run by both the upstart and sysvinit (and therefore systemd) scripts.
Test case: ls /run/hugepages
Regression potential: since init scripts are being moved around, there is a potential for this to go wrong.
=======
As stated by Dadio (dominique-
On 15.04 upstart isn't standard anymore...
Now the qemu-kvm.conf upstart script isn't run.
Shouldn't the upstart script be converted to a regular systemd script?
Right now, the hugepages functionality isn't working anymore on Ubuntu 15.04...
Additionnaly, I saw that systemd launch the LSB job /etc/init.
dg@pc-david:
juin 02 10:49:50 pc-david systemd[1]: Starting LSB: QEMU KVM module loading script...
juin 02 10:49:50 pc-david systemd[1]: Started LSB: QEMU KVM module loading script.
So, old LSB script should be removed (or disabled) when new qemy-kvm.service will be added for systemd.
