We observed that some threads can reach deadlock-ish state after they have Invoked into a control's UI thread. When it happens they are all in a waiting for join or in sleep state for very long time, although there should not be any deadlock situations.
It seems this has something to do with multiple parent controls and with which control we invoked on. This should not make a difference, because we have got one UI thread (for MainWindow) they should wait for, but we have seen it does.
The solution that fixed this issue was to invoke on the MainWindow instead of various controls (see a4fe507adf ).
This changeset is changing all our Invokes to invoke into MainWindow
instead of a control itself. (MainWindow's UI thread is the only UI thread
all Control is using in XenCenter)
This changeset should be in place until we have found the root cause or the exact reason for the above.
- this applies to the Cloud-config page on the New VM Wizard and VM properties dialog.
- same for the container enlightenment page on the VM properties dialog.

- The cloud config parameters page is only visible on a VM that already has a config drive.
- The cloud config parameters can only be changed when the VM is halted.
- In the New VM wizard, if a template is selected that already has a config drive, them the wizard will display the existing configuration, not the default one.

- Added check for Clearwater SP1 or greater to the gpu capability on the New VM wizard
- On the GPU tab, draw the grid on the shiny bar only if the capacity is greater than one

Changes following code review:
- Added VM.CanHaveVGpu function (at the moment just returns CanHaveGpu, but it will change in the future)
- Added vGPU_type.IsPassthrough function and used it everywhere we needed to test for passthrough (max-heads==0)
- Simplified code in Helpers.GpuCapability, Helpers.VGpuCapability, NewVMWizard (gpuCapability), MainWindow and GpuRow

New properties:
- Pool.HasGpu = Pool has at least one PGPU
- Pool.HasVGpu = Pool has at least one PGPU that HasVGpu
- PGPU.HasVGpu = PGPU has at least one supported_VGPU_type that is not pass-through
New or modified helper functions:
- Helpers.GpuCapability = GPU feature not restricted (by licensing) and Pool.HasGpu
- Helpers.VGpuCapability = vGPU feature not restricted (by licensing) and Pool.HasVGpu
- Helpers.ClearwaterSp1OrGreater = API version is 2.1 or greater
The GPU dialogs are displayed as follows:
- GPU page on VM properties dialog: Visible only if VM.CanHaveGpu and the GPU feature not restricted (by licensing)
- GPU page on New VM Wizard: Visible only if VM.CanHaveGpu and the pool has GPU capability (Helpers.GpuCapability)
- GPU page on Pool properties dialog: Visible only if the pool has vGPU capability (Helpers.VGpuCapability)
- GPU tab: Visible only if the pool has GPU capability (Helpers.GpuCapability) and is Clearwater SP1 or greater
- On the GPU tab, the "Placement policy" panel: Visible only if the pool has vGPU capability (Helpers.VGpuCapability)
- On the GPU tab, the "Edit" button on the "vGPU types" panel: Visible only if the PGPU.HasVGpu and vGPU feature not restricted (by licensing)
Also:
- VM.CanHaveVGpu function renamed to CanHaveGpu
- On the GPU tab, renamed "Allowed vGPU types" to "vGPU types
- Show the page and grey out the irrelevant options (i.e. the installation media if the template has no CD drive).
- Only disable the Installation media step if the template has no installation media and we don't show the boot options (because is HVM).

Also GPU page on Pool properties dialogs should not be shown for non vGPU pools.
