Re: [Kimchi-devel] [PATCH][Kimchi 3/6] Fix checking duplicate template before creating it
Nice catch to check if the template already exists a little bit early
than current code. But I guess would be better if you do the check in
the beginning of the method, preventing the execution of all unnecessary
process the method does and will not be used.
What do you think?

Template was being check if duplicated after calling for VMTemplate,
which can make unecessary work. Check it before creating the class.
