[chef-dev] Re: Knife-vsphere vs powetCLI

[Anna Redding < >]

Thank you for the DNS info. 
 
Based on the RFC, my hostnames are compliant so this does appear to be a bug 
I'm experiencing. 

Actually, I believe I have three valid bugs I've encountered but want to try 
and make sure it's not something weird on the vcenter side of the house 
before I blame knife-vsphere!!!
