Subject Re: CloudStack with XenServer on single host
Date Sun, 02 Nov 2014 13:14:18 GMT
Hi Rafael.

That's certainly a clever way of getting it to work, however if you were to put the Host into
maintenance mode, or reboot it, all the VMS would stop and you would have no way of restarting
them.

The original poster is new to CloudStack and needs to learn how it works.  I don't think we
should encourage the use of complex 'hacked' deployments which could give them problems in
the event the Host is restarted etc.

Actually, you can have CS running on a Xen server host that it is running;
however it is a little bit tricky, because when you add a xen server, the
CS does not load any VM configuration that it already has running.

I did that myself in the Cloud that we have in our networking and
management lab.

I first installed CS in a temp machine and added the hosts I wanted to
manage to CS.

Then, I created 4 instances (you most certainly do not need that much) one
for the CS-database, CS1 and CS2 and an Apache Webserver working as a load
balancer.

After that, I stopped the CS that was in the temp machine, migrated the
database for the cs-database VM, configured CS1 and CS2 to use that
database that is in the VM. Configured the Apache web server, and that is
it. You now have a CS environment that runs on physical machines and VMs
that it manages.

Unfortunately you cannot run CloudStack Management Server on a XenServer
(or ESXi) Host it is managing.

It works for KVM because CloudStack and KVM are running as services on
CentOS, CloudStack is not running as a VM on KVM.

You do have a couple of options however:

Install Virtualbox and then create a VM for CloudStack and a separate VM
for XenServer - take a look at this recent presentation I have at the
European User Group


http://www.slideshare.net/ShapeBlue/building-virtualised-cloudstack-test-environments

This is really aimed at testing on a Laptop, if you have a physical box a
better option is to install the free version of ESXi then add a CentOS VM
for CloudStack and a XenServer VM as your Hypervisor.  If you configure
ESXi for nested virtualisation your XenServer will support HVM VMs, unlike
on Virtualbox which will only support PV VMs

Hello,

is there any way to install the CloudStack management server as VM on
XenServer 6.2.0 which will also added as host for instances?

It is possible to install it on CentOS host with KVM but I do not find any
information regarding XenServer VM. In the documentation it is stated, that
there should be no running VM on XenServer but I am not sure, if there is
no possibility. I evaluate to create an environment with a single server in
the first step.

Thanks
