Add support for the 'cpu_models' option in nova.conf
Since OpenStack Train release the 'cpu_models' config option
has superseded the 'cpu_model' config option in the nova.conf.
This patch adds support for the new 'cpu_models' allowing a user
to provide a comma separated list of supported, named CPU models.
This patch also includes a unit test for the cpu_mode='custom'.
These updates, on the master branch, are to support testing the caracal
packages and support of the charms for caracal. They do NOT lock the charms
down, and don't change the testing branches to stable branches.
[v2] Fix migration across nova-compute apps using ceph
This change reworks previous changes [1] and [2] that had
been respectively reverted and abandoned.
When using the config libvirt-image-backend=rbd, VMs
created from image have their disk data stored in ceph
instead of the compute node itself.
When performing live-migrations, both nodes need to
access the same ceph credentials to access the VM's
disk in ceph, but this is currently not possible
if the nodes involved pertain to different
nova-compute charm apps.
This patch changes app name sent to ceph to
'nova-compute-ceph-auth-c91ce26f', a unique name common to
all nova-compute apps, allowing all nova-compute apps to
use the same ceph auth.
This change also ensures newly deployed nodes install
the old credentials first on ceph-joined hook,
and then supercedes it with the new credentials
on ceph-changed hook, therefore also retaining
the old credentials.
This patch also includes the charmhelpers sync
from PR: #840
When using NVMeoF feature with nova-compute apparmor in enforce
mode, nova-compute is denied from running /usr/sbin/nvme and
/usr/sbin/blkid, and reading /etc/nvme/hostnqn.
Nova-compute uses ssh and scp commands extensively and this
patch allows the process to read the configuration too in
/etc/ssh/ssh_config.d/ directory.
Patch out charmhelpers.osplatform.get_platform() and
charmhelpers.core.host.lsb_release() globally in the unit tests to
insulate the unit tests from the platform that the unit tests are being
run on.
