I use thin provisioning, so the space for the VM drive file isn't allocated
until it's needed. I also have scripts to monitor free space on the
physical drives so I can take action if they're in danger of running out of
space.

I`ll chime in, I`m running a centos 7 kvm setup, should do it in a
container but ive been lazy. The mythtv is a kvm vm with a whole disk
passed through for storage, that way I can mount my disk outside of myth if
needed etc.  You can do that with a vm disk but just easier for me if i
need to do it in the future etc.
