Joshua Boniface e984f315f1 Correct bug in finding system template list 2020-10-29 12:14:10 -04:00
Joshua Boniface ec0b8acf90 Support per-VM migration type selectors
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.

Joshua Boniface d63e757c32 Ensure args are checked against form body
Required for XML definitions but erroneously removed during file parsing
reworking.

Joshua Boniface f85c2c2a75 Remove PyWSGI and move to Flask server
Gevent was completely failure. The API would block during large file
uploads with no obvious solutions beyond "use gunicorn", which is not
suited to this. I originally had this working with the Flask "debug"
server, so just move to using that all the time. SSL is added using a
custom context with the OpenSSL library, so include that as a
dependency.

Joshua Boniface ffaa4c033f Improve handling of large file uploads
By default, Werkzeug would require the entire file (be it an OVA or
image file) to be uploaded and saved to a temporary, fake file under
`/tmp`, before any further processing could occur. This blocked most of
the execution of these functions until the upload was completed.

This entirely defeated the purpose of what I was trying to do, which was
to save the uploads directly to the temporary blockdev in each case,
thus avoiding any sort of memory or (host) disk usage.

The solution is two-fold:

  1. First, ensure that the `location='args'` value is set in
  RequestParser; without this, the `files` portion would be parsed
  during the argument parsing, which was the original source of this
  blocking behaviour.

  2. Instead of the convoluted request handling that was being done
  originally here, instead entirely defer the parsing of the `files`
  arguments until the point in the code where they are ready to be
  saved. Then, using an override stream_factory that simply opens the
  temporary blockdev, the upload can commence while being written
  directly out to it, rather than using `/tmp` space.

This does alter the error handling slightly; it is impossible to check
if the argument was passed until this point in the code, so it may take
longer to fail if the API consumer does not specify a file as they
should. This is a minor trade-off and I would expect my API consumers to
be sane here.

Joshua Boniface a4b80be5ed Add provisioned memory to node info
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.

Joshua Boniface 973c78b8e0 Use monkeypatch to allow multithreaded prod flask
Without this tasks were blocking when other task were active (for
instance, any task with --wait). Using the moneypatch, these no longer
block.

shutdown migration.

Joshua Boniface 34c4690d49 Don't convert bytes into KB in OVA import
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.

Joshua Boniface db558ec91f Complete implementation of OVA handling
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
