Using Xen Server and KVM together
Hi..
I have been using cloudstack using KVM for some time and would now like to
add a new cluster with Xenserver Hosts..
I wished to know is that possible for a single cloudstack management server
to handle both Xen and KVM? If yes can anybody tell me how to proceed to do
the same?
Its because the templates for system VM for Xen are different than that of
KVM and I read that adding support for Xen has to be done before setting up
the Management Server. I would not like any changes to my current
cloudstack management server as currently some VMs are running on it.
Also I wished to know is Intel VT necessary to be enabled for Xen too like
it is for KVM. I browsed a few links and they said that Xen can also work
without Intel VT enabled from the BIOS given extensive GUI based processing
is not required on the VMs. So does Cloudstack accept Xen Hosts with Intel
VT enabled?
Regards

Hi Tilak,
CloudStack can most certainly manage kvm and XenServer at the same time.
Firstly download the latest XenServer system VM Template in line with the install docs for your version.
You then need to setup the Xenserver Traffic Labels on each network in CloudStack, setting them the same as the actual names of the networks or bonds you have setup on your XenServer hosts.
Regarding lack of Intel VT support you need to run the following to update the database BEFORE you try adding the hosts
mysql -p<password> cloud -e \ "INSERT INTO cloud.configuration (category, instance, component, name, value, description) VALUES ('Advanced', 'DEFAULT', 'management-server', 'xen.check.hvm', 'false', 'Shoud we allow only the XenServers support HVM');"
Finally take a look at http://shapeblue.com/cloudstack/xenserver-native-ha-with-cloudstack/ to help you setup XenServer Management HA.

If you terribly want XenServer where you are not in a position to run XenServer on host machine, with some cost to performance - you ran run XenServer as a VM on ACS+KVM+CentOS setup.

I'm assume, the documentation here doesn't reflect the real
capabitilies. I've tried Xen/libvirt on Ubuntu to no success. For
gettings things simply done, I moved over to XenServer.
Anyway, this is speculative. If someone knows if (and how) Xen with
libvirt can be used with ACS, I would highly appreciate any hints!
Cheers,

Hi Lucian,
I believe thats not true. Because I was just going through installation
docs of cloudstack 4.0.2 here
https://cloudstack.apache.org/docs/en-US/Apache_CloudStack/4.0.0-incubating/html-single/Installation_Guide/
and it clearly lists that " *The current release of CloudStack supports
pre-packaged enterprise solutions like Citrix XenServer and VMware vSphere,
as well as KVM or Xen running on Ubuntu or CentOS.*" in the first para of
section 1.2.
I am using cloudstack 4.4.1. Is the support for Xen running on CentOS taken
out of the version I am using i.e. 4.4.1?

Hello Tilak,
I believe ACS does not support Xen/libvirt, only Xenserver.

Re: Using Xen Server and KVM together
Posted by Tilak Raj Singh <ti...@gmail.com>.
Thanx Geoff and Tim for your quick replies..
I cant use Xen Server as I wish to use Xen within centos. I needed some
more help as to how to setup Xen Hosts for cloudstack. I installed Xen on
my CentOS 6.5 x86_64 version using this link
http://wiki.centos.org/HowTos/Xen/Xen4QuickStart
Can somebody provide me official cloudstack links for systemvm templates
for Xen? I am using cloudstack 4.4.1 as my management server.
I wanted to know what else will I have to do except for downloading the
systemVm templates for Xen on my management host except for adding that
entry into my cloud.configuration table as Geoff told in the same thread.
Also I would like to enquire do I have to switch to manual networking and
close the network manager and create a cloudbr0 bridge for Xen host too
like we do for KVM?

Tilak,
You can definately do this. Take a look at my multiple hypervisor preso
for 4.4 for some tips:
http://www.slideshare.net/TimMackey/hypervisor-selection-in-apache-cloudstack-44
XenServer does need Intel VT, and that's a good thing all around.
