Totally agree... Experiences with Solaris Containers PROOVES, that 
Container Technology has very specific use cases, and typically fails 
due to OPERATIONAL incapabilities of the organisations...

So, Docker as well as containers will not be the solution to all things 
"virtualization" as well as "management"...

Still, Docker is an important part, but it will definitively NOT replace 
hypervisors (Type 1!). With Type 1 hypervisors standard operations can 
still be applied (on top of RHEV or VMware!), and that's the simply 
reason, why they've been so successful!
