Bug ID: 44705
           Summary: Let users pick their favorite VMs
           Product: Wine-Testbot
           Version: unspecified
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: unknown
          Assignee: [e-mail]

Now that it's possible to have multiple snapshots per VM there will be a lot
more test configurations. When a user submits a job he may only be interested
in some of them but currently he will have to systematically unselect those he
does not want (or select the extra ones he's interested in).

For instance one may not be interested in the various locale VMs when working
on a mutex test for instance; or on the contrary only be interested in the
locale VMs and not in the other Windows versions when working on a locale
related test.

When going through a few iterations of a test this can quickly become
bothersome. So it would be nice to provide a way for a user to pick the VMs to
be selected by default.

* This could be a user setting dialog.

* Or the TestBot could automatically remember that user's last VM selection and
reuse it for the next job.

* Or there could be a 'Use the same VMs as for the last job' button. This could
either go to the next step, or remain on the page and adjust the VM selection
using a bit of JavaScript.

On the backend side this information could be stored in the form of a UserVMs
table with the following columns:
  UserName
  VMName

Then the Submit.pl script would read from this table to initialize the VM
selection table for step 2 of the submission process.
