Subject Re: mgmt node on kvm host

In short,

Never, EVER, do such thing (especially in production of any kind).

Mgmt server (any auxiliary components like standalone DB server, billing
software, monitoring software, load balancers etc - all things that are
needed for production...) can be on KVM nodes, but a standalone KVM nodes,
which are NOT managed by CloudStack. Whether you use VMM from Linux
Desktop, plain/manual management via libvirt and "nano" etc...all good as
long as not managed by ACS - you want to avoid cyclic dependency and mgmt
server issues due to high host usage/overload, etc, etc, etc.
