Subject RE: Error: "Unable to add host"
Date Fri, 15 Apr 2016 02:06:55 GMT
If you have resources, it is recommended to have management server and host on separate machines.
But just to troubleshoot your environment you can check the below link and see if things work.

From my understanding you are trying to setup everything ( management server and hotst) on
a single machine. The error you face is generally seen if the hypervisor host doesn't have
KVM agent installed properly (I might be wrong here). Can you please go through the below
link and make sure that you have followed all the required steps (for KVM installation ) and
confirm if KVM is properly installed (say by checking lsmod | grep kvm ) ?

Subject: Re: Error: "Unable to add host"

The managenent ip address is the same as the host ip address, and the same as the machine
that I'm using...
I've done this because I've followed the Quick Installation Guide that is focused on doing
everything in the same machine, and this guide specifies to use the same ip addresses in managenent
server and the first host.

I am interested in getting started on CloudStack doing this "trial"
installation, so I don't need lots of resources (and actually don't have them at this moment).
For this reason I think doing everything in the same machine is the best option for me.

If you could help me doing this that would be great, or if it's not possible and you think
it's better and easier separating the management server and host, I could look for another
machine to use.

Thank you very much.
