[libvirt-users] RAID1 over IP?

[David Ehle]

That makes a lot of sense... I don't know that I really needed the full 
suite, as I don't think I'm aiming for that level of  HA for the hosted 
systems.

I'll look into it. Can you provide me any better links than what a google 
search would provide?

Thanks!

David.
