As I keep saying over and over and over again, power savings are _not_ a
feature of virtualization. Power savings is a feature of
consolidation. Virtualization is for absolute isolation. MythTV,
MySQL, Samba, Postfix, Dovecot, Apache, Cacti, and any number of other
applications will all live happily right next to each other on the same
system. In fact, since you're likely sharing the same data in Samba as
you are using in MythTV, it in fact makes far less sense to run those in
a virtual machine, considering one or both of them is going to have to
access those local disks through a network share.
The only thing mentioned there that would necessitate a virtual machine
would be Windows Server. However, that questions the need for Server
2k3. It's sitting in a cupboard, so you're not using it as a desktop.
Were you using it for development work, you likely would have upgraded
to 2k8. You're running Postfix/Dovecot, so it's not hosting Exchange.
Is there no Linux alternative to whatever you're running on there?
