[ale] Hypervisors and such

Yes, fair point!  I didn't mean to imply that I was looking for a hvz to 
run containers.  I simply meant that ProxMox has some value add in that 
it manages containers as well as VMs through it's GUI.

As far as virt-manager, I do recall learning to use that wwwaaaayyyy 
back in 2011 or 2012ish.  I'll give that another look.  I'm fine with 
spinning up a VM that is a docker-host.  No issues there.  I just had 
draw to proxmox, again, because it was pretty and all in one place.

If you have multiple VM host machines, does virt-manager/libvirt/KVM 
handle migrations between devices and such, or is that value add that 
another tool/product provides while utilizing KVM under the hood?  I 
don't think it did back in the day, but time flies and things change.
