Allow a VM to specify its migration type as a default choice. The valid
options are "default" (i.e. behave as now), "live" which forces a live
migration only, and "shutdown" which forces a shutdown migration only.
The new option is treated as a VM meta option and is set to default if
not found.
Since these will almost always connect to an IP rather than a "real"
hostname, don't verify the SSL cert (if applicable). Also allow the
overriding of SSL verification via an environment variable.
As a consequence, to reduce spam, SSL warnings are disabled for urllib3.
Instead, we warn in the "Using cluster" output whenever verification is
disabled.
Don't try to chmod every time, instead only chmod when first creating
the file. Also allow loading the default permission from an envvar
rather than hardcoding it.
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
Instead of using group-based validation, which breaks the help context
for subcommands, use a decorator to validate the cluster status for each
command. The eager help option will then override this decorator for
help commands, while enforcing it for others.
Use a different wait method of querying the node status every
half-second during the transition, in order to wait on the transition to
complete if desired.
Closes#72
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

Rename "pvcd" to "pvcnoded", and "pvc-api" to "pvcapid" so names for the
daemons are fully consistent. Update the names of the configuration
files as well to match this new formatting.
References #79
Warn the administrator if there are active provisioning jobs while
adjusting the current primary node. This is the simplest, cleanest
solution to #69 without trying to implement any hacks or blocking
operations. The administrator can then decide to revert the action
if needed, or will at least know how many jobs are running/queued and
may need to be cancelled.
Move everything from under "storage ceph" to "storage" to simplify the
CLI; additional subclasses can be re-added at a future time if and when
additional storage classes are supported.
Implements a "maintenance mode" for PVC clusters. For now, the only
thing this mode does is disable node fencing while the state is true.
This allows the administrator to tell PVC that network connectivity,
etc. might be interrupted and to avoid fencing nodes.
Closes#70
Implements the storing of three VM metadata attributes:
1. Node limits - allows specifying a list of hosts on which the VM must
run. This limit influences the migration behaviour of VMs.
2. Per-VM node selectors - allows each VM to have its migration
autoselection method specified, to automatically allow different methods
per VM based on the administrator's preferences.
3. VM autorestart - allows a VM to be automatically restarted from a
stopped state, presumably due to a failure to find a target node (either
due to limits or otherwise) during a flush/fence recovery, on the next
node unflush/ready state of its home hypervisor. Useful mostly in
conjunction with limits to ensure that VMs which were shut down due to
there being no valid migration targets are started back up when their
node becomes ready again.
Includes the full client interaction with these metadata options,
including printing, as well as defining a new function to modify this
metadata. For the CLI it is set/modified either on `vm define` or via the
`vm meta` command. For the API it is set/modified either on a POST to
the `/vm` endpoint (during VM definition) or on POST to the `/vm/<vm>`
endpoint. For the API this replaces the previous reserved word for VM
creation from scratch as this will no longer be implemented in-daemon
(see #22).
Closes#52
This is likely not going to be used with the planned implementation of
the automatic provisioning daemon, which will be either an API client or
direct Python binding client.
