On the host create/edit form, the 'Operating System' tab contains a few grammar mistakes and styling issues:

• The description for the Custom Partition Table field should be changed. It contains missing/poor punctuation, missing spaces, and misspellings (ex. 'what ever'). I personally don't find it very helpful as is.
• In certain scenarios, the description for the root password field gets bumped from right of the password entry to below the password entry (screenshot below). In this state, it does not conform to the left margin that other form elements follow. It should probably always be below the root password box like other descriptions.
• The Custom Partition Table text box can be resized freely. It should probably be locked on the horizontal axis like the comment box on the 'Additional Information' tab.
