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. Regards, Andrija On Thu, Jun 20, 2019, 20:48 wrote: > How are most of you running your management node?
