Re: çå: [Xen-users] XEN large scale cluster

Hi Dika,

The XenServer client seems can't connect to XEN server.

Xenserver client (XenCenter) connects to XenServer (closed source, but with version that are free), so yes it cannot connect to standard Xen.

However you should have a look to XCP (http://www.xen.org/products/cloudxen.html , the FOSS version of XenServer). It currently does not provide transparent migration of storage from one physical server to another, but it should mostly offer what you want. Currently you cannot use XenCenter to connect to XCP, but there are some other tools to do so. There is also a python API so it would be rather easy for you to build up a simple custom front end for your customer.



Best wishes,

Dika Ye

Dear All,

We are preparing amount 400 servers to deploy a large scale XEN
cluster; I am looking for the best solution for that, these are some
things I need to resolve:

1)       400 servers use raid-1, each server will have more than 100GB
free disk space, I want to combine all of these for the cluster's
storage, so, it need to install the distribute file system;

2)       How to deploy the high availability of XEN server?

3)       How to assign the resources pool for each customer?

4)       We provide virtualization service for our customers, the
customers would use a GUI tool to connect for managing the virtual
server, they can install they own VM, adjust the VM's memory, CPU or
hard ware resource, what tool can support these features?

Thanks in advance for any advice or opinions on this.

Best wishes,


You could have a look at openQRM.

im the Community-Manager @openQRM and it does absolutely not fit in this


Im just pointing out my notes in form of a wiki, which i hope is
tomorrow online. i would fill it with some more content, dcescriboing
such a setup.

stay tuned,

Why not? It was my understanding it is meant to provision VMs for clients
while they can pick their own specifications and that the created guests are
offered in a HA way.

For this kind of setup you would rather look at CloudMin or Cirtrix XenServer
