Distribution of the RAID in a guest virtual machine in Windows Server

Hello

Before I try this 'new', is it a performance advantage, or any particular configuration that would make any advantage of net return for a vm of comments Windows Server running on VM Workstation if I add a bunch of virtual drives and raid stripe them together via the Guest Windows Disk Manager. I would do that on a single disk physical host so I would venture to guess that the stress of the e/s on a disc single physical host can be a bottleneck in any scenario like that. I wonder if the VM Workstation has a way to compensate for the stress of IO because it presents me with a very impressive interface SCSI virtual (the one that allows a large number of virtual SCSI disks) and multiple SCSI channels. I have to admit that I already tried this scenario in a RAID Configuration 5 with eight (0-7) virtual disks on SCSI Channel 1 (a separate channel from the customer 'boot' virtual disk on SCSI channel 0 virtual machine.) In fact, it worked but was extremely slow. I hope that it is only because RAID 5 is a very demanding configuration on disk IO anyway so it is demanding a lot of physical i/o to the single disc physical host accordingly. However, I also hope that maybe a simpler configuration as striping RAID 1 could make a net profit of performance. The reason that I'm in any medium Green is because I observer that a guest running Windows 7 computer gets better scores to Performance Aero it's Windows 7 host (but that's another debate). Someone at - it here never geeked with scenarios of striping raid like that on VM Workstation 7.x configuration?

Go ahead, say it. You know I'm a total geek

See you soon,.

Hello

If you do this on a single drive host I would expect horrible performance - just the opposite of what you want to acchieve.

As Wil mentioned already... only several axes you can get best performance from disk

    How the Virtual Machine has been backed up and restored?  If Time Machine then...

    It is a known fact that Time Machine is not 100% reliable backing up/restoring VMS in all circumstances/conditions.  Also back up Virtual Machines via Time Machine of disk/time intensive and wastes a lot of space for something that may be corrupted and worthless time to restore it.  At least I would exclude the Virtual Machines with virtual machines and Time Machine shutdown, not suspended and VMware Fusion closed and then manually copy the VMS to another location, preferably on a different physical hard drive.  So keep the user data stored in the virtual machine saved out of the Virtual Machine on a regular basis in order to always have a backup of the current user data.  If you need to restore a properly saved by VM is not as common at least you will have a virtual working Machine and data user to go forward with when you find out your Time Machine backup of the virtual machine fails.  Also take a look at: best practices for backup of virtual machine (programs and data) in VMware Fusion (1013628)

    That said, if you don't have a copy of the file "Windows 7 - f004.vmdk" and then to try to retrieve the data from the user, you can try the following:

    Download then unzip it (double-click on) the joint "Windows_7 - f004.vmdk.zip" file that contains the file "Windows 7 - f004.vmdk ' an empty logical binary measure that has been created on the metric of the existing drive and add to the Package of the Virtual Machine.  This should allow the VHD to be considered as a virtual hard drive, assuming that there is no damage to the extent of the binary left headers.  Take a look on: work with Virtual Machine packages

    At this point, that the VHD has the scope necessary to show as a full disk, assuming that it is not corrupt the header in other binary extensions and can now attempt to access for the recovery of user data.

    There are several ways to try to retrieve user data.  The easy, although not necessarily work properly according to what now lack us due to replace the missing binary extensions with a logical empty measure, is trying to start the VM normally.  If the virtual machine starts up on the desk and VMware Tools load properly you should be able to copy your data to user off on a USB or slip and fall on the side of Mac or if you have a configured VMware folder then copy the files through it.

    Other methods involve starting the Virtual Machine with a Live OS ISO Image and copy files from a USB key or temporarily assemble the VHD to another Virtual Machine work.

    With the right tools installed the virtual hard disk could also be mounted as another accessible Volume through Finder.

    that will depend entirely on the Organization of the underlying hardware and the OS and app loading on these drives.  Having said that, generally, is not a big deal provided that machines have anyway enough RAM.

  • Deleting the same files of many virtual machines remotely

    Hi all

    I tried to delete the same file several virtual machines remotely using the following script PowerCLI:

    $a = Get - VM | %{

    foreach ($nic as $_.) Guest.Nics) {}
    Write-output $nic. IPAddress
    }
    }
    foreach ($i in $a)
    {$b = get-WmiOBJECT-query "SELECT * from CIM_DataFile where Name='C:\\test\\deleteme.exe'"-computername $i}
    $b.delete)

    }

    It works perfectly when I run the script on the host virtual machines while I am running the script PowerCLI. When I Connect-viserver to another host however and try to run the script, I get the dreaded "RPC server is unavailable error (HRESULT: 0x800706BA)" for Get-WmiObject.  Virtual machines don't have Windows Firewall and have all TCP/IP, RPC and WMI services started, so who could eliminate any possibility.

    I am also able to run other scripts that use the Get-wmiobject across all virtual machines such as scripts to change the DNS or Netbios name across many machines on different hosts.

    Any comments would be greatly appreciated and please feel free to comment if you know maybe other ways which can delete files on multiple virtual machines in any other way.  Installation PowerCLI to run the script locally on each host would be a laborious process to do.

    Thank you very much!

    To solve the problem with the quotes, you can use double quotes inside the string. Like this:

    «del "«c:\documents and settings\text.exe»»»

    Or you can use for the string single quotes and double quotes inside:

    "del"c:\documents and settings\text.exe"

  • Is it possible under the EULA to have several virtual machines on a single physical hard disk while using the same OS license or do I need a separate license for each virtual computer?

    I have several programs that are not compatible with my 64 bit Windows 7 operating system.  I would like to run each different software under another virtual machine of VMWare (5 packs of different software programs and 5 different virtual machines of Windows XP).  These would all be installed on your laptop.  I can use the same license of Windows XP for each virtual machine, or do I need a separate XP license for each (different XP in case 5 licenses)?

    It is lifted directly from my EULA:

    1. GRANT OF LICENSE.
    The manufacturer that you grant the following rights, provided that
    comply you with all terms and conditions of this EULA:
    1.1 installation and use.  You may install, use, access,
    display and run one copy of the SOFTWARE on
    THE COMPUTER.  The SOFTWARE may not be used
    by more than two 2-processor both on the
    COMPUTER, unless a greater number is
    indicated on the certificate of authenticity.
    Then...
    This means that as long as you are running two or more instances of XP at the same TIME, you agree? Or does this mean that, after you install once, you have reached your limit?
    I imagine that most people (including those who are running Microsoft!) will say that the second interpretation is correct.
    However...
    If this is the case, anyone their hard drive as a backup to clone strategy would violate the EULA!
  • Not possible to export a list of virtual machines that are created in the past 7, 30, 120 and 180 days since an imported csv file containing the date of creation of virtual machine

    Not possible to export a list of virtual machines that are created in the past 7, 30, 120 and 180 days since an imported csv file containing the date of creation of virtual machine. My questions is the correct statement to the variable: $VmCreated7DaysAgo: $_CreatedOn "-lt" $CDate7.

    # #SCRIPT_START

    $file = "C:\Users\Admin\Documents\WindowsPowerShell\08-18-2014\VM-Repo.csv".

    $Import = import-csv $file

    $VMCreatedLast7RDayRepoFile = "C:\Users\Admin\Documents\WindowsPowerShell\08-18-2014\Last7Days.csv".

    $start7 = (get-Date). AddMonths(-1)

    $CDate7 = $start7. ToString('MM/dd/yyyy')

    $VmCreated7DaysAgo = $Import | Select-object - property name, Powerstate, vCenter, VMHost, Cluster, file, Application, CreatedBy, CreatedOn, NumCpu, MemoryGB | Where-Object {$_.} CreatedOn - lt $CDate7} | Sort-Object CreatedOn

    $TotalVmCreated7DaysAgo = $VmCreated7DaysAgo.count

    $VmCreated7DaysAgo | Export-Csv-path $VMCreatedLast7RDayRepoFile - NoTypeInformation - UseCulture

    Write-Host "$TotalVmCreated7DaysAgo VMs created in 7 days" - BackgroundColor Magenta

    Invoke-Item $VMCreatedLast7RDayRepoFile

    # #SCRIPT_END

    You can use the New-Timespan cmdlet in the Where clause, it returns the time difference between 2 DateTime objects.

    An example of this cmdley

    New-TimeSpan-start (Get-Date). AddDays(-7)-end (Get-Date). Select days - ExpandProperty

    In your case, you could do

    Where {(New Timespan-démarrer ([DateTime] $_.))} CreatedOn) - end $start7). {7 days - gt}

    But beware of negative numbers.

  • Set the priority of restarting a virtual machine

    Hello

    I'm trying to set the priority of restarting a virtual machine in a cluster. I worked along THIS DISCUSSION to create this script:

    Where Cluster and VM are objects of the WF input.

    Executions of thoughts scripts, however, in the CR, I get the error «the parameter of {entry.@enum.» InvalidDasConfigArgument.EntryForInvalidArgument} is not valid for the cluster.

  • How to connect the physical monitor in a virtual machine?

    I connected a monitor of my laptop, I want to use this screen for my virtual machine running Windows 7, so the virtual machine runs in fullscreen display them on the monitor and not on my laptop. Is this possible? I'm using Vmware workstation.

    WS = Vmware Workstation

    Your laptop must be supported using the second monitor as an extension on the desktop, only not in mirror as it does now. This is done from your video settings, has nothing to do with VMWare.

    Go into your video settings and see if the monitor shows up as Monitor #2, then look for a setting to put it right (or left) of your laptop monitor. My Thinkpad supports this mode.

    Check with the manufacturer of your laptop if necessary. Lou

  • URGENT! After installing 6 Fusion and creation of new virtual machine with Windows 7, I get a message "VMware Fusion cannot enter the unit". WHAT SHOULD DO?

    After purchase, installation and activation Fusion 6 with the license key, I had a library of VMS showing 2 Boot Camp partitions. It's strange that I only have 1.
    I tried to activate them but received a message that it is out of date in 2 cases. (see annex 1)

    I started a new virtual machine with a Windows 7 installation disc directly on my HD. I have provided a way to do this and followed the instructions of Fusion to the screen.

    Apparently, everything went well and after several restarts, the installation appears to be over (see annex 2) I tried to open and run the installed Windows 7. I had however a window with the following message:

    "Pending the unit.

    "VMware Fusion cannot enter the unit. Please wait until the unit starts automatically, or interact with the virtual machine below. ' (see annex 3)

    Here Windows 7 seems to start but after a while with the home screen and of the Øresund finishing this window closed and open a new window called library Virtual Machine on the left showing the partitions of Bootcamp and the Virtual Machine Windows 7 x 64 and in the middle gray a representation of what is supposed to be the Windows 7 desktop. (see Exhibit 4). When I opened the settings button a window with different setting options pops up. This mark means to me that Windows is installed but the final opening isn't the case

    When you quit Vmware Fusion indeed Windows seems to be close (see part 5)

    What is going on? What has gone wrong? What should I do? I don't know how to solve the problem.

    I should f.i. remove the virtual machine from Windows 7 and is free automatically made partition on my HD as the reboot with the Windows installation disc? or y at - it another way to enter the UNIT?

    Help, please!

    Thanks in advance

    Your virtual machine is running. It is in the unit - which each windows gets its own window of Mac - and you have no application Windows running, there is no visible windows. You can start a Windows application in the start of Fusion menu in the menu bar at the top right, or turn on the Windows task bar on the view menu and start applications from there. Or use the view menu to switch to the Single mode or full-screen, which puts all of your Windows desktop in a window separate from Mac.

    You do not have two partitions to Boot Camp on your Mac, you have two virtual machines named "Boot Camp partition".

    The message about it being unable to enter the unit arrives while the merger is pending for the tools begin to run, because the tool is necessary for the unit.

  • What is the advantage to affect multiple virtual machines in a data store?

    Hello

    Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.

    Thank you

    By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

    As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

    In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

    Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.

  • Lion running as a virtual machine under Windows (in front of the normal).

    Long story short, I'll install Windows (natively) on my MBA (lots of reasons - application compatibility, management files, etc.) but would like to have OS X on the side to play with. Anyone have any experience using OS X Lion in a virtual machine under Windows? Since it IS an Apple computer brand, I think it would be legal Yes? I'm guessing there will be VM Tools, but again, since it is an MBA, the drivers should be built anyway?

    Thank you

    First VMware does not support Mac OS x (and version) running under Windows!

    Mac OS X Lion, which is preinstalled cannot be legally virtualized and to virtualize Mac OS X Lion, you need to have a copy that was purchase on the App Store or on USB and then can only be virtualized on Mac OS X Lion!

  • Cannot save the virtual machine in VMWare Server 2

    BTW: what is ESX, ESXi and what version of ESXi is included in VMWare Server 2?

    Thank you very much

    Luis

    I can't tell you exactly what are the causes of the problem. What I would try (a solution) is to create a new virtual machine in VMware Server with the same specifications as the original one, then copy the two files hard in the new virtual machine folder and edit the .vmx file for the new VM 'OpenSuSE - 12.1 - cl1 - 000001.vmdk' use as its virtual drive.

  • Dual boot MacBook running Win as host, not to run the Mac partition as a virtual machine?

    I have a MacBook which double - start by training camp.  I generally run Windows but do have occasional need to pop in Mac.

    Is there a way to get my Mac running as a virtual machine in Windows partition?  I've seen a lot of discussion of the scenario opposed using Mac and Fusion, but not found on my installation.

    Thanks in advance for any help, especially if it's the ten thousandth time it was requested.

    Within the limits of your question, it is not supported by VMware.  That means that the only product from VMware that supports the legal vitualization of legally virtualisables versions of Mac OS X is VMware Fusion when run under Mac OS X on a Mac to processor Intel.

    In addition, if it's not Mac OS X Server 10.5, 10.6. 10.7 or Client Mac OS X 10.7, so he is not allowed by the Apple ALS and cannot therefore be discussed in these forums without violating the terms of use of the VMware community.
