No.  Data centers would not survive today without consolidation, and 
consolidation without virtualization is a big security concern.

The issue here is one of hardware access.  Unless you're using a network 
attached tuner like a HDHomeRun, mythbackend is going to need hardware 
access.  This is something that is of zero concern to data center users. 
  If hardware access were simple, we wouldn't have people repeatedly 
asking in here if it could be done, they would just do it.  So, you have 
a bunch of people who are asking to do something virtual machines are 
ill suited for, for reasons other than what virtual machines are 
intended for.

If you don't need the security that comes with virtual machines, and 
your application has needs that cause problems with virtual machines, 
don't use use them.  If you still want the ease of management you get 
with isolation, you can still do that without the virtual machine. 
Build your applications with different prefixes, and play games with the 
environment and LD_LIBRARY_PATH.  Chroot your applications into their 
own system install.  Use FreeBSD Jails or Linux Containers for memory 
and network isolation.
