As Geoff said I am new to the complete topic CloudStack. I worked only wit= h XenServer in the past and now evaluate CloudStack which I think seems to = be the better option for XenServer as OpenStack. Of course it should be more easier to create a VM for the management serve= r as I also have different XenServer and therfore the question. When I read= the answers I think the only useful way is to install CloudStack on a dedi= cated server or VM of a host which is not also a node for CloudStack. For the evaluation I will now install a CentOS host with KVM on a single d= edicated server. One small question: I read that also Xen is an option. I can not find any information regardin= g Xen in the documentation, is it official supported by CloudStack? Thanks =C2=A0 Gesendet:=C2=A0Sonntag, 02. November 2014 um 14:32 Uhr Von:=C2=A0"Rafael Weingartner" An:=C2=A0"users@cloudstack.apache.org" Betreff:=C2=A0Re: CloudStack with XenServer on single host You are right, I am just using this deployment, because I have an environment with more than 1 server. We actually have 3 clusters, and we spread the system vms (router and etc) and CS vms (database, CS1, CS2 and apache) into different clusters. So, if I for some odd reason I need to restart a physical server, I can still migrate VMs before the restart. I just presented our work around to show that it is indeed possible. But, as a said, it can be tricky, especially if you have an environment with just one server. BTW: out of curiosity, if you use CS in an environment with just one physical server, would you call it a Cloud?
