  • How do I run my application while a UAC dialog window is showing?

    - by Ray
    I have an application that I wrote in .NET. It needs to remain running and have access the desktop that the UAC dialog windows open on and interact with that desktop using keyboard and mouse events. It's sort of like a VNC program. Imagine you are running a VNC program and a UAC window pops up, you want your VNC program to still be able to control the desktop with the UAC window in it so that the user can move the mouse and click the OK button on the UAC dialog. Can anyone tell me how I would go about doing that? Thanks

  • New virtualization project and old SAN

    - by Chris
    Hi, We'll start shortly a partial virtualization of our infrastructure and consolidate a dozen servers into virtuals instances. We'll also add some client application virtualization into the mix for good measure. Two HP DL 380 with the new xeons 56xx and 96 GB of memory each running xenserver + xenapp will then take charge of most of our IT needs. So far, so good. One element that is missing from the picture is the storage part. We need some sort of shared storage to enable live motion and other HA features. We have an IBM DS 4300 SAN that we can use for that. But since it's in production since 2005, I'm not sure about such a critical role for a 5yr old part. So my question is: What is the reliability of this kind of equipment after 5 yr ? Can it last 10 yr with no or few problems ? Since our budjet is tight, not buying another SAN will be a big plus. This lead me to another question: FC disks cost an arm and a leg from IBM. When I type the replacement # in google (for example IBM 300GB 15K 4GBPS FC HDD 42D0410), I can find it at a fraction of the price at various sites. So am I stupid to buy from IBM or naive to trust 3rd party reseller ?? Thanks, Chris

  • Wastage of resources in Virtualization

    - by Sabeen Malik
    I have asked this question on SO, but was suggested that i ask it here on SF, so here it goes. http://stackoverflow.com/questions/3010753/wastage-of-resources-in-virtualization I am not sure if this is the right place to ask the question. However i hope it is. When looking for a VPS earlier today, I was trying to understand how each container would work in the background. Keeping in mind the fact that the operating system uses most of the memory and power on a system, wouldn't having multiple operating systems in the same machine mean more wastage of resources. For instance if i was running centOS on a dedicated box and it was running lets say 20 background OS level processes. Then i go and install a virtualization platform and install 5 more centOS virtual machines in the same system which are exactly the same as the host operating system. Doesn't this mean duplication of those 20 processes 6 times? So internally the context switching is happening between 120 processes instead of 20? Further Notes: Here is an example of what i am thinking: I have a master-slave configuration for a long running, cpu + memory intensive process, which can be distributed to 4 machines. Lets say when the process runs on these 4 machines with lets say 1 Gh CPU and 1 Gig RAM, i get 400 results per hour from the cluster (assuming 100 results from one machine) . Now i get a bigger machine ( lets say 4Gh and 4 Gig RAM), have 4 virtual hosts on it with 1 Gz CPU and 1 Gig RAM. Will this configuration give me the same 4 results per hour from these 4 virtual hosts?

  • Install virtualization software on a remote linux machine as a non-root user

    - by Cetin Sert
    Hi, 1) Is there a way for me to install VirtualBox as a non root user? I compiled it from the sources but cannot find a way to load the kernel modules it requires? Is there anyway to make it run? 2) Is there any other virtualization software you have ever installed on linux successfully as a non root user, VMWare, Parallels, etc.? The aim is to run Windows as a virtual machine with more than 16GB RAM. Bests, Cetin

  • Best virtualization solution for running Windows 7 as a guest?

    - by gkt.pro
    I depend upon Ubuntu for most of my work but I still need Windows 7 for some applications such as Office 2010 Casual Gaming Adobe CS4 and other windows softwares that are not available on Ubuntu yet. I checked Wine but as of now it provides no support for Office 2010 and most of my games and softwares. So, I decided to go for Virtualizing Windows 7 inside Ubuntu, but I am confused about which virtualization software should I use on Ubuntu for virtualization.

  • How can virtualization be efficient?

    - by pestaa
    As I understand, the virtual machine and the guest OS doubles the amount of abstraction layers (that are computationally relevant) between the user interface and the pure power of the hardware. Some of the said abstraction layers are (emulated) hardware, drivers, IO interfaces, etc. Top-notch virtualization solutions like Xen probably eliminate a few of these complexities, but I still wonder how efficiency is achieved in these environments; and whether manageable cloud servers are really worth the performance price.

  • Help desk cannot respond to UAC prompts over Remote Assistance

    - by blsub6
    I'm trying to use the in-built Remote Assistance (RA) software in Windows 7 to support my users. I initiate a RA session with the user and ask to remotely control their desktop. They tick a little check box that says something to the effect of 'allow helper to respond to UAC prompts' and it pops up with a UAC prompt. The user cannot respond to the UAC prompt because they're not a local administrator - I am. Isn't that what that little check box is for??? I've found this on TechNet from back in '07 on Vista. From what I've found, I could disable UAC (terrible idea) or make all my users local administrators on their computers (yet another terrible idea). I'm hoping that MS has fixed this little oversight in Windows 7. Remote Assistance is completely useless to me if I can't respond to UAC prompts with my username and password

  • Windows 7 sharing data between users via the registry

    - by r99
    Where can I create/modify/delete registry keys to share data between users in the Windows 7 registry? Both of the users are non administrators and it shouldn't require admin privileges. The application I'm working on uses the registry to write a key from userA and then userB can read/modify/delete it. Neither user has admin privileges and it won't be possible to change this. Is there an official MSDN guide to how to use the registry in Windows 7? Any links describing proper use of the registry would be useful.

  • A tale of UAC on a Windows 7 Development Machine

    - by TATWORTH
    This week I faced an interesting problem on a Windows 7 Development PC. I have run MakeLog (http://commondata.codeplex.com/releases/view/13206) sucessfully on my PC but my colleague could not run it sucessfully. Both of us are local administrators, so what I could do on my PC, he should have been able to do. The cure was to turn UAC completely off and re-boot. Once re-booted, the installation ran without incident. While I would never suggest turning off UAC normally, on development PCs, it is a liability as it stops many normal operations and occasionaly without giving a prompt.

  • Enable hardware virtualization in BIOS?

    - by rhon
    I am running a FOXCONN AM2+ M61PMV with an AMD Athlon II X2 240 Windows 7 ultimate 64 bit. From startup I have hit the del key and the options for enabling the hardware virtualization are not there. I have checked the Microsoft tool that says I can run virtual and i have checked SecurAble, that says yes. But I have an open case w/microsoft (they've been trying for a week [7 tech support people later]) and they're saying that I need to ensure that the hardware is enabled. Where do I go to see? Is there another way besides from the startup?

  • Using WebSphere CloudBurst with PowerVM to AIX virtualization over a cloud

    - by ADD Geek
    hi there we are studying the virtualization option to reduce our datacenter cost, and this research was assigned to me. we looked into alternatives and we almost reached a conclusion that PowerVM is the only option to virtualize pSeries servers. we found no signs of cloud support explicitly mentioned in any document, however there was the mention of CloudBurst. from the videos we watched and the documents we read, it seems that CloudBurst is more oriented towards Application Servers (WebSphere Software). but our environment is not relying only on WebSphere. we have some banking applications, Oracle Databases and MQ/Broaker. the question is: 1- can we virtualize the existing applications (all running AIX) on a cloud running on top of some of the existing servers? (given that we do the sizing properly) 2- is PowerVM to run on top of CloudBurst? 3- if the above solution is applicable, is this some sort of HA solution (since the VM will run on top of multiple physical boxes, while the same physical box will run multiple live images) thanks for your help

  • Set up a root server using Ubuntu and Virtualization

    - by Daniel Völkerts
    Hello, I'd like to setup a fresh root server and install a linux based virtualization on it. My thoughts are on: Intel VTs Hardware Ubuntu 9.10 KVM based virt. The access to the root server will only be SSH for Administration. Has anybody done this before, what was your glues discovered in the daily use? My requirements are: very secure, so the root server only has ssh to the dom-0 and minimalistic ports for the guest (e.g. http/s). good monitoring of host/guest (my idea is to using zabbix for it) easy and fast administration (how are the command line tools working for you? cryptiv? high learning curve?) I'm pleased to learn from your suggestions. Regards, Daniel Völkerts

  • What virtualization solution should I try next, after hitting problems w/ VMWare Player in dual-netw

    - by Alex R
    I have been using VMWare Player 2.5 for a while (Ubuntu guest on Vista host, 32-bit). VMWare had worked great until now but then I hit a brick wall: Due to some reorganization of my home network, the host machine now has to use a wireless connection to reach the Internet, while the printer, fileserver, and other important stuff are attached to a local gigabit hub. I have tried several tricks, such as editing the .vmx file, changing settings in vmnetcfg, etc, but I'm still unable to get the virtual Ubuntu box to connect each of the two virtual NICs to different networks (I did get it to recognize two NICs, but both DHCP'd onto the gigabit LAN). So, I'm ready to dump vmware for something with a little more low-level control of network settings. Virtualization is such a crowded space, I could spend months evaluating every product out there. I'm hoping for a shortcut... Can anyone recommend the best VM for my situation described above? Thanks

  • How (much) is virtualization used today?

    - by BLAKE
    I know that where I have worked, I have pushed alot for virtualizing our servers. I think that it is much easier to implement and maintain than physical servers. I have been using Microsoft's Virtual Server 2005 R2 since it was released. Right now at my workplace we have 12 VMHosts that hold about 55 VMs. We have 6 other servers that we have been unable to convert to VMs. I want to know how other people in our field view virtualization. I know that I have had developers dislike the notion of VMs claiming major performance hits. What do other Sys Admins think about virtualized servers?

  • Which simple server virtualization solution to use?

    - by vvanscherpenseel
    For one part of our hosting platform we are currently using VMware Server 2 to create two virtual machines on one physical machine. One VM is used for hosting of small websites, the other VM is used as a staging environment. Both the host OS and guest OSes run CentOS Linux. Support for VMWare Server 2 has been discontinued and we are currently looking for a replacement. We only use basic functionality (we don't use snapshots, moving around VMs to different physical machines, or other 'advanced' functionality'). Just a box, with two VMs. We are looking for a virtualization solution that has long-term support, is stable and allows configuration/management from Mac OSx (I understood that Xen only has a Windows client). What would be the right solution for us?

  • Multiple workstation setups using virtualization - best solution

    - by Vazgen
    I'm looking to set up a server for my small startup. I have a few employees and would like to use my computer at home to provide them all with workstations. Each workstation should have the same collection of software installed but each user's workstation should be completely separate from the others. I need each user to be able to remotely log in to their workstation (using TeamViewer or something like it) and I want to be able to monitor their workflow from my screen. I suppose I need a virtualization solution. Can anybody recommend one with easy set up, I'm not a server administrator.

  • Hardware Virtualization no longer required for Windows 7 XP Mode

    - by Jonathan Kehayias
    One of my frustrations in upgrading to Windows 7 last year was that Virtual PC no longer worked since I didn’t have Hardware Virtualization on my CPU.  This really drove my transition entirely to VMware Workstation on my personal laptop.  I recently reinstalled my work laptop (with permission) on Windows 7 Enterprise and figured I’d give XP Mode a look since this machine has Hardware Virtualization enabled.  I was surprised to find that Hardware Virtualization was no longer required,...(read more)

  • Virtualization in Ubuntu 9.10

    - by Jeff Dege
    I have an existing Centos 5 installation. I would like to upgrade to Ubuntu. Thing is, I don't want to be down for as long as it will take to get my entire environment moved over - software installed, connectivity configured, etc. I'd like to take it one step at a time. But I don't really want to keep rebooting back and forth from the new OS to the old OS. That's what I did last time I upgraded to a new OS, and it got old real fast. So, since my new MB is virtualization-ready (AMD Phenom II 945 quad-core), I figured I could create a virtual machine, under the new OS installation, that ran the old OS installation. The problem is that the documentation I've been able to find has been pretty sparse. I've found a lot of possibilities, and little info on which would be capable of doing what I want. I have a new Ubuntu 9.10 installation, and a second disk containing the Centos 5 installation. And I don't know where to go next. Any help would be appreciated.
