Adds a separate field to the node memory, "provisioned", which totals
the amount of memory provisioned to all VMs on the node, regardless of
state, and in contrast to "allocated" which only counts running VMs.
Allows for the detection of potential overprovisioned states when
factoring in non-running VMs.
Includes the supporting code to get this data, since the original
implementation of VM memory selection was dependent on the VM being
running and getting this from libvirt. Now, if the VM is not active, it
gets this from the domain XML instead.
Makes this output a little more realistic and allows proper monitoring
of the Ceph cluster status (separate from the PVC status which is
tracking only OSD up/in state).
Make the provisioner a bit more robust. This way, even if a provisioning
step fails, cleanup is still performed this preventing the system from
being left in an undefined state requiring manual correction.
Addresses #91
Allow the specifying of arbitrary provisioner script install() args on
the provisioner create CLI, either overriding or adding additional
per-VM arguments to those found in the profile. Reference example is
setting a "vm_fqdn" on a per-run basis.
Closes#100
Provides a CLI and API argument to force live migration, which triggers
a new VM state "migrate-live". The node daemon VMInstance during migrate
will read this flag from the state and, if enforced, will not trigger a
shutdown migration.
Closes#95
Doing so can create an image that is 1 sector (512 bytes) too large,
which will then break qemu-img because it's stupid (or, VMDK is stupid,
I haven't decided which is).. Current Ceph rbd commands seem to accept
--size in bytes so this is fine.
Ensure all API return messages are formated the same: no "error", a
final period except when displaying Exception text, and a regular spaced
out format.
Finishes a basic form of OVA provisioning within the existing create_vm
function. Future plans should include separating out the functions and
cleaning them up a bit more, but this is sufficient for basic operation.
Closes#71
Add functions for uploading, listing, and removing OVA images to the API
and CLI interfaces. Includes improved parsing of the OVF and creation of
a system_template and profile for each OVA.
Also modifies some behaviour around profiles, making most components
option at creation to support both profile types (and incomplete
profiles generally).
Implementation part 2/3 - remaining: OVA VM creation
References #71
Add management of the pvcprov database with SQLAlchemy, to allow
seamless management of the database. Add automatic tasks to the postinst
of the API to execute these migrations.
