mirojr Posted March 5, 2012 Posted March 5, 2012 Hiya, Am trying to setup this proof of concept Xendesktop network. I have server 2008 R2 running within vmware esxi4 running the citrix desktop studio Can i use a physical machine as my shared Desktop? ta
Abaddon Posted March 5, 2012 Posted March 5, 2012 Yes, but why not go the whole way and use a virtual desktop.. were you planning on having a pile of desktops in your server room? Or blades?
mirojr Posted March 5, 2012 Author Posted March 5, 2012 Currently my esxi server is a bit short of resources, well actually I have not really looked closely at resources so that may just be a bad guess, anyway just wanted a quick proof of concept and I have a Win 7 laptop here that I can use to demonstrate
mirojr Posted March 5, 2012 Author Posted March 5, 2012 I have almost setup this xendesktop thing, but I keep getting this error: No available resource found for user domain\myuser when accessing desktop group MyUsers Desktop. Am looking for any ideas what the cause maybe Thanks.
scifidale Posted March 5, 2012 Posted March 5, 2012 When you ran the quick deployment setup (presumably) did you specify an AD group or user (that you are using to test with) for the published desktop?
mirojr Posted March 5, 2012 Author Posted March 5, 2012 its an AD user if i remember. It appears in the Assignments window as "MYDOMAIN\Myusername" like this
mirojr Posted March 5, 2012 Author Posted March 5, 2012 I tried to send a message to the physical machine i am using: Script history: Sends a message to the session(s) This script sends a message to a session or sessions. 05/03/2012 11:40:27 Send-BrokerSessionMessage -InputObject @(3) -MessageStyle 'Critical' -Title 'test' -Text 'test' -AdminAddress '2K8server.mydomain.domain.co.uk:80' Send-BrokerSessionMessage : Session operation error - attempted:1, failed:1, succeeded:0 + CategoryInfo : InvalidOperation: ( [send-BrokerSessionMessage], SdkOperationException + FullyQualifiedErrorId : Citrix.XDPowerShell.Broker.SessionOperationFailed,Citrix.Broker.Admin.SDK.SendBrokerSessionMessageCommand
jamesfed Posted March 5, 2012 Posted March 5, 2012 You haven't mentioned your deployment size but could I suggest you take a look at Citrix VDI-in-a-box 10x as simple as full on XenDesktop with all of the key features (linked clones, Citrix HDX, CAG support ect). All you do is load up their pre setup VM and boom you have a VDI network - no mucking around with config settings and very easy to get going as a test deployment.
kevvo2000 Posted March 5, 2012 Posted March 5, 2012 I agree with jamesfed, VDI-IN-A-BOX is very easy to set up, it does have it's limits however - one of which is the inability to use dynamic memory within a Hyper-V environment (don't know about VMWare). Also the educational pricing is good.
mirojr Posted March 5, 2012 Author Posted March 5, 2012 Thanks I am gonna download this appliance for vmware. I was wondering also while I am here is it possible to have mutiple connections to a single physical machine whilst using this xendesktop trial. I dont want to bother trying if its not possible If anyone knows Ta
jamesfed Posted March 5, 2012 Posted March 5, 2012 By multiple connections do you mean multiple thin clients (or whatever endpoint you are using) to connect to a single virtual desktop? If so as far as I'm aware its not possible and isn't one of the normal uses of VDI. Again if so could you let us know what you are trying to accomplish and we can see if there is a better option for you
mirojr Posted March 5, 2012 Author Posted March 5, 2012 (edited) Multiple thin clients connecting to one physical desktop. So i could log on as 2 different users and share the physical machines resources Edited March 5, 2012 by mirojr typo
jamesfed Posted March 5, 2012 Posted March 5, 2012 That sounds a little more like Remote Desktop Services than VDI. In RDS you have a server which allows multiple users from multiple devices to login at the same time - they can't see each others 'sessions'. In a VDI setup you have a server which hosts virtual machines - each virtual machine has a single user from a single device logged into it.
mirojr Posted March 5, 2012 Author Posted March 5, 2012 Ye the 2 technologies are kinda the same in respect to clients logging into a server to receive a desktop, whether these desktops are virtual machines or one server with TS running. The multiple VM sounds great but it sounds like it would be a major load on any server? Would it not be better to have a server that allowed multiple connections, cause i presume these VMs would have to all be on all the time even when not in use? All new to me really thin computing TS etc Thanks for your input
localzuk Posted March 5, 2012 Posted March 5, 2012 (edited) Multiple thin clients connecting to one physical desktop. So i could log on as 2 different users and share the physical machines resources That is confusing. What do you mean 'physical desktop'? XenDesktop uses a single physical machine, and creates multiple virtual machines on that hardware, each user connecting gets one of those individual desktops. This uses more resources, but offers a more seamless and 'normal' desktop experience to the end user, as it prevents any possible interference between instances of software. XenApp or RDS is a single physical machine, with a single operating system where multiple users connect to that single instance as concurrent users. Which are you trying to achieve? The resources needed for VDI are not *massively* different, as they are instead based upon a mix of individual resources and a dynamic use of memory, where only 1 copy of something will get loaded into RAM and shared across the different machines. The biggest bottleneck in VDI is usually the hard disks - as it requires a lot of IOPS to handle any decent amount of load. Edited March 5, 2012 by localzuk
jamesfed Posted March 5, 2012 Posted March 5, 2012 Just to reiterate I think we are going to need to know a little more about what you want to accomplish before suggesting anything further. Is this for a IT room PC refresh or something?
mirojr Posted March 5, 2012 Author Posted March 5, 2012 That is confusing. What do you mean 'physical desktop'? Physical desktop, i mean physical machine. Currently this is a demo for my boss, I am using a laptop as a desktop rather than a VM
mirojr Posted March 5, 2012 Author Posted March 5, 2012 The end product would prob be having maybe 10 thin clients in class rooms. Also ipads being able to use windows desktop
localzuk Posted March 5, 2012 Posted March 5, 2012 (edited) That is confusing. What do you mean 'physical desktop'? Physical desktop, i mean physical machine. Currently this is a demo for my boss, I am using a laptop as a desktop rather than a VM In which case, either solution does what you want - the difference is the multiple virtual machines or a single terminal services setup. The prior will be able to host less clients than the latter, but a normal desktop machine running this sort of thing would be able to handle a hand full of VDI machines without much issue. The question is more one of what exactly the larger picture is though - a demo is fine set up either way, but what is the larger project likely to be used for, if it were? EDIT: Replied before I clicked reply... In which case, I'd say for that sort of volume of machines, either solution will work on a single server host quite easily. The cost comes when you start scaling upwards. Edited March 5, 2012 by localzuk
mirojr Posted March 5, 2012 Author Posted March 5, 2012 Ta The end product would prob be having maybe 10 thin clients in class rooms. Also ipads being able to use windows desktop . Currently with the demo I seem to be only able to log on with one user at a time, would be nice to show the boss multiple users utilizing the same physical machine (without having to have xenserver and VMs) but I maybe unable to have more than 1 connection to the laptop that I am using to show demo.
jamesfed Posted March 5, 2012 Posted March 5, 2012 Making more sense now Personaly I will opt for VDI in most uses these days as it gives a bit more flexiablity than traditional RDS and also the Citrix HDX protocal in VDI-in-a-box is great for video playback ect (send me a PM and I can send you some YouTube links). Mix it in with something like App-V and you will have a rock solid thin client network for years to come. There is a aditional cost in VDI compared to RDS though in the fact it needs more CPU cycles, more RAM and more IOPS but with things like SSDs and Windows Server 8 Hyper-V with memory de dup on the way it could be the thing for you.
mirojr Posted March 5, 2012 Author Posted March 5, 2012 Cant try out the VDI demo as it does not support my free esxi. Woe is me
