is it possible to run more than one XP Mode Virtual Machine RRS feed

  • Question

  • Hi there!

    I wonder if it is possible to define more than one virutal machine on a Windows 7 environment.

    There's anyone who knows about this issue?

    Thanks

  • XP Mode is enabled by a technology called RAIL (Remote Applications Integrated Locally). XP Mode also includes a prebuilt and licensed XP virtual machine. You can create a virtual machine using your own XP or Vista media and install a RAIL QFE for those operating systems. As of the date of this post, these downloads are not currently available.

    If you aren't interested in publishing applications to your desktop, you can create a virtual machine without installing a RAIL QFE. Because the underlying Windows 7 Virtualization engine is based on Virtual Server 2005 R2 SP1, it is multithreaded and can support multiple virtual machines running simultaneously. The number of virtual machines you have running simultanesouly is limited in practice by your available hardware resources (and as Tom pointed out, legally limited to yor available licenses). Each virtual machine competes for hardware resources. If you have a quad core machine, you can easily run three virtual machines - each vm has a processor core with one left over for the host system. If you have a single core machine, running more than one virtual machine will most likely cause sluggish response.

    When you allocate ram to virtual machines, it's very important not to allocate so much ram to the virtual machines that your host system is starved for ram.

    I regularly run 2-3 virtual machines on my quad core Windows 7 machine with 8 GB of ram.

    Hi,

     

    From the VXPEULA.txt file (you can find it in the folder which created by installing XP Mode), we can find the following content:

     

    1.1 Installation and use.  You may install and use one copy of the Software in a single virtual machine on a single computer, such as a workstation, terminal or other device (“Workstation Computer”) that contains a licensed pre-release copy of Windows 7 Ultimate edition, to design, develop and test your programs for use with the Software.

     

    Note: Please understand that current XP Mode is still an RC version. Thus the " END-USER LICENSE AGREEMENT" may be changed when the retail version is released.

     

    From the EULA, we are not allowed to use several "XP Mode" on the same computer.

     

    Of course, as "tgoodson" mentioned, we can create a second virtual machine by using a regular Windows XP installation disk with the license on the disk. But please understand that it will be a new system and we will need to manually configure it. For example, we may need to manually install drivers, setup share permission (with the host system) etc.

    For detail & latest information about licensing, it is recommended to contact our Product Sales and Licensing.

  • It is if you have an extra XP license to use.  Create a new virtual machine, install Windows XP, upgrade to SP3 and install the integration components.  Next you'll need to download an addin for the virtual machine to allow you to publish applications to Windows 7.  I don't recall right now where I found that at, but it is available as a download from Microsoft.

    Lookup KB961742-v3 to get the software for published applications.
