Check out the VDI features of the product.

You should consider desktop virtualization with specific applications such as Citrix XenDesktop. They deliver the applications to the user's desktop while being executed on the servers.

Look into <a href="http://www.vmware.com/products/view/" rel="nofollow noreferrer">VMware View</a>. They are working on version 4 which should greatly improve performance. I am looking at this product for a small number of desktops.

Also Windows Server 2008 R2 has some new VDI features to take a look at.

That's what <a href="http://www.qumranet.com" rel="nofollow noreferrer">Qumranet</a> used to sell before being bought by Redhat.

For this, they developed KVM as open source (and quickly got included in the Linux kernel), of course, the rest of the stack was closed source, including the remote display protocol which they claim is the best there is. They also had an admin console, simple clustering of hardware and load-balancing by live-migration of VMs

The website is still up, and the product (SolidICE) seems to be available.

I haven't used the product, but would be my first stop if I wanted to virtualize desktops.

There are several layers that you need to understand and separate,

<ol>
<li>Access point (your sunray)</li>
<li>Connection broker, this is a service that the access point connects to, to retrieve either a list of desktops, or to auto launch a desktop</li>
<li>Connection protocol the protocol the client will use to intimate the connection to the VM, e.g. RDP, ICA, PCoIP.</li>
<li>Hypervisor, the host with VMs running ontop.</li>
<li>Application Virtualisation, this layer is optional, and realistically unrelated to VDI. This just allows you to make your VMs relatively stateless by allowing users to connect to any VM to run their applications without a lengthy install.</li>
<li>Profile management, another optional layer to allow user settings and preferences to roam with them.</li>
</ol>

You can generally mix and match solutions from different vendors. E.g. Hyper-V with XenDesktop for broker and protocol.

Some brokers allow you to spin up VMs on the fly, keeping a list of idle machines, rebooting / re-building on logoff etc...

Keep in mind the significant 'porting' effort you'd need to undertake to virtualise your applications (re-package everything), and profile management if you go down the stateless route.

I am looking into virtualizing desktops for a large office, and I haven't been able to figure out how I would accomplish access to a VM instance per user.

We are considering using sunrays as our point of access, from which I assume we would launch a VNC connection into a VM. At this point I'm at a bit of a loss -- how would I ensure that we either launch a VM if it is not already running, or connect to their existing VM if it is already running? Or would the solution here be to make sure that all possible instances are already running, but 'paused' until someone tries to connect to them?

We are are still considering our options in terms of virtualization -- Hyper-V, KVM, Xen, or other.. on one hand we're enthusiastic about open-source products so KVM and Xen are attractive choices, but on the other hand we want administrator training to be as painless as possible so products like Hyper-V have their allure too.

I know this is a fairly sprawling topic I've put up, but I'd appreciate any advice anybody has to offer on the topic.

Thanks!

我正在研究一个大型办公室的桌面虚拟化，我还没有弄清楚如何实现每个用户对VM实例的访问。我们正在考虑使用太阳光作为我们的接入点，从这里我假设我们将启动一个VNC连接到一个VM。在这一点上，我有点不知所措--如果VM还没有运行，我们如何确保启动它，或者如果它已经在运行，就连接到他们现有的VM？还是这里的解决方案是确保所有可能的实例都已经在运行，但“暂停”直到有人试图连接到它们？我们仍在考虑我们在虚拟化
