Description of problem:
After updating the engine to 4.3 if you edit or add a host and attempt to set multiple kernel command line options it fails with 'This field can't contain spaces'.
Version-Release number of selected component (if applicable):
Worked on 4.2
Steps to Reproduce:
1. Add or Edit a host
2. Select 'Kernel'
3. Attempt set multiple kernel command line options e.g 'hugepagesz=1G hugepages=230'
Won't let you proceed. Field is red, mouse-over shows 'This field can't contain spaces'.
Can proceed. Command line options set for kernel.
This can also hinder if you already have multiple command line options set and have to edit the host for other reasons (cluster change, etc). It won't let you proceed unless you remove the additional options, but then you have no way to re-apply them through the gui.
Setting a single option without any spaces works fine.
I couldn't find any notes about a delimiter change for this field.
This is likely to be an effect of https://bugzilla.redhat.com/show_bug.cgi?id=1478854
The regular expression used is whitespace only, and shouldn't block "normal" whitespaces
