Yes, that's impression I was getting, too, but it is a bit of a bizzare 
limitation.

I suspect this is to do with Java on the client side. The KVM/media 
client is Java based and it complains at startup that it couldn't find 
various native libraries. Googling around the subject indicates that the 
management app only comes with 32-bit support, and CentOS 7 only comes 
with 64-bit icedtea-web. :-(
