Description of problem:
I have encountered an issue with Operating System dropdown in VM Wizard (in the basic settings tab).
The issue is that sometimes when the dropdown is opened, it contains only few options, as if common templates were not installed. However, after some time, the content of the dropdown is reloaded and all options are displayed appropriately.
All the OS types should be loaded at the time the VM Wizard is opened.
See attached video sample, especially the attempt after 0:20, in which the loading takes significant amount of time.
Version-Release number of selected component (if applicable):
around 50%, maybe less
Steps to Reproduce:
1. Open VM Wizard
2. set provision method
3. open OS dropdown
Sometimes the content of the dropdown is reloaded quite long after the dropdown is opened
The dropdown should have defined up to date content at the time VM Wizard is opened and loaded.
Not an issue from automation perspective, but it doesn't look good from user point of view

Verified that OS dropdown is now disabled until content is preloaded.
