    Un buen gesto:Virtual Hard Disk format released under Open Specification Promise

    Virtual Hard Disk format released under Open Specification Promise

    A while ago we announced that we were making the VHD format available, royalty free, to people who were interested in using it in their products.  Today we have announced that we are releasing this format under the Open Specification Promise (OSP).  If you are not familiar with the OSP - checkout: http://www.microsoft.com/interop/osp/default.mspx.  In layman’s terms it means - go for it.  Use it for free - it is fine by us.

    For more details about the VHD specification - checkout: http://www.microsoft.com/windowsserversystem/virtualserver/techinfo/vhdspec.mspx

    Cheers,

    Ya puedes descargar la beta de Virtual PC 2007

    Recuerda que si tu procesador soporta virtualización asistida por hardware tus maquinas virtuales iran mas rapidas.
     
     
     

    VMware Infrastructure 3: Leading the Transition to 64-bit Computing

    Me gusta Virtual Server, pero por desgracia y segun para que, vmware esta por delante.

    VMware Infrastructure 3: Leading the Transition to 64-bit Computing

    The latest release of the award-winning VMware ESX Server and VirtualCenter furthers your ability to pervasively deploy virtualization with full 64-bit OS support, non-disruptive upgrades and product localization.

    VMware Infrastructure 3 delivers systems infrastructure capabilities for entire farms of servers and storage, independent of the application/operating system workloads and of the underlying hardware.

    New features in VMware Infrastructure 3 include:

    * Full support for 64-bit guest operating systems facilitates the adoption of high-performance 64-bit applications such as Oracle, IBM DB2, and MySQL, SAP R/3 and MS Exchange. This allows for simultaneous 64-bit and 32-bit operating system and application environments.

    * Support for less expensive storage options like iSCSI SAN and NAS makes it easier and more cost effective to deploy VMware Infrastructure

    * VMware DRS dynamically provisions, migrates and manages computing capacity across resource pools to changing business requirements

    * VMware HA increases availability by automatically restarting virtual machines on live production servers in the event of server failure

    * Support for enterprise workloads with virtual machines with up to 4 processors and 16 GB of physical memory

    Hotfix for VS2005R2SP1 on AMD hardware virtualization systems

    Hotfix for VS2005R2SP1 on AMD hardware virtualization systems

    I have heard from a couple of people who have hit this issue - so I thought I should make a post about it.  If you attempt to run Virtual Server 2005 R2 SP1 on an AMD system with hardware virtualization - you are likely to see a large number of blue screens.  The reason for this is that the x64 versions of Windows guard a number of privileged system registers that have been used maliciously in the past - and cause a system crash if someone tries to fiddle with them.  As it turns out they are guarding a register that we need to modify for completely legitimate reasons.

    To get around this there is a hotfix that you need to install on Windows first.  This hotfix is available from the Virtual Server beta download page at: https://connect.microsoft.com/Downloads/DownloadDetails.aspx?SiteID=151&DownloadID=3045

    This hotfix applies to both the 64-bit versions of Windows Server 2003 and Windows XP.

    IDE vs SCSI under Virtual Server

    There has been some confusion over when users should use SCSI or IDE virtual hard disk inside of their virtual machines.  The first thing to note is that it does not matter what sort of physical hard disk you have in your computer when you are making this decision.

    There are a number of factors to consider:

    • Our emulated IDE can only support 4 disks, while our emulated SCSI supports up to 28 disks
    • Our emulated IDE can only support up to 128GB disks, while our emulated SCSI can support up to 2TB disks
    • Our emulated IDE controller has a higher level of driver support for various operating systems than our emulated SCSI controller

    The final thing to consider is performance - and this is a bit tricky.  Contrary to common sense, the performance of our emulated SCSI controller is slower than that of our emulated IDE controller.  The reason for this is that the SCSI controller is a lot more complicated to emulate than the IDE controller.  Now - this changes once you have Virtual Machine Additions installed.  As part of Virtual Machine Additions we install an accelerated SCSI driver.  Once this driver is installed the performance of our emulated SCSI controller is significantly faster than our emulated IDE controller.

    So with all of this in mind, my recommendation is this:

    • If you are running Windows NT, 2000, XP, 2003 with Virtual Machine Additions installed; use SCSI.
    • If you are running any other configuration; use IDE unless you specifically use more than 4 disks, or larger than 128gb disks

    Windows Server Virtualisation has the following system requirements:

    • Longhorn Server x64 Edition AND
    • System with hardware assisted virtualisation (either Intel VT or AMDV (formerly Pacifica))

    To be explicit, Windows Server Virtualisation will NOT run on:

    • Windows Vista
    • Longhorn Server 32-bit (x86) or Itanium (IA-64) versions
    • Systems that don’t have Intel VT or AMD-V (Pacifica)

    Otra de SCVMM

    Creando una maquina virtual.

    Fijaos en como el SCVMM te propone en que servidor host poner el guest y como cualifica las alternativas.

    Me encanta este producto.
