Why would you want to?  Mythcommflag and mythtranscode can be 'niced' so 
they don't impede other processes.  If you artificially govern the 
database and backend, MythTV will just become slow to respond as it is 
waiting on the database or scheduler to finish.  The database and 
backend will use however much memory they want, and nothing you do 
externally can reduce that.  If you limit them to less memory than they 
want, something will be randomly terminated by the kernel, and you won't 
like the results.

Virtualization will only serve to increase memory usage, as you lose the 
ability to use shared libraries, and you are going to duplicate 
everything in the disk cache.

So what? Even a basic 'chroot' will allow you to do that.
