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
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.
