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.
Prevents a rare edge case where a node can end up "migrating" to itself.
Quick hack to fix this, though like most of the VM management should
probably be rethought/rewritten later.
Fixes#92
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.
Make sure the stopping of the keepalive timer and final keepalive update
are done as the last step before complete shutdown. The previous setup
could conceivably result in a node being fenced should the cleanup
operations take longer than ~45 seconds, for instance if primary node
switchover took too long or blocked, or log watchers failed to stop
quickly enough. Ensures that keepalives will continue to be run during
the shutdown process until the last possible moment.
