• Increase the size of the virtual disk.

  I just installed Windows virtual PC on Windows 7 64 bit and I try to install a program of 6 GB.  He said that there is not enough memory.
  The size of the virtual disk in less than 2 GB and I can't find any way to increase this size.  I tried to create a second virtual disk with more memory, but the same error comes back.  Is there a way I can increase the size of the primary virtual disk?

• Unable to connect to the virtual disk Service, Virtual Disk Manager Interface not registered

  I installed Windows 7 Ultimate on this laptop as a new installation about six months ago.  Since then, I don't think I ever ran diskmgmt.  Today, I joined a new external hard drive usb, it reported the drivers installed fine, but then the installation bombed at the beginning.  I went to verity, what had happened and has run diskmgmt.msc (as an administrator), but she came back with the message "Unable to connect to the virtual disk Service" and also a small OK msgbox appeared with the title "Virtual Disk Manager" and the "Interface not registered" message

  I disconnected the USB hard drive and tried again diskmgmt, but no change.

  I restarted in safe mode, tried diskmgmt, but no change.

  I ran sfc/scannow, but it has reported that it found no errors.

  I checked that the virtual disk service has been configured as a textbook in services.msc, and event viewer showed that when I ran diskmgmt he started VDS and then stopped VDS.

  I tried again, but still not like before.

  Is there some dll I can't regsrv32?

• Could not load the virtual disk manager

  I am operating Windows 7 SP1. At one point, I lost the ability to use the virtual disk manager. I've scoured the web and many forums to find answers and none worked. I tried to repair windows, run sfc/scannow, etc stopping before you reinstall windows, which some people have suggested that I have many software loaded and am not sure that this will not happen again once I loaded the software again.

  It is a "backdoor" way to force launch disk management? My need is to change disks on some of the hardware devices, such as DVD players and card readers.

  Would appreciate any advice or suggestions... Thanks in advance.

  Hello

  Thanks for the reply.

  Glad to know that you were able to solve the problem. Your efforts to solve this problem is appreciated. Feel free to post your request here on the Forums of Windows, we would be happy to help you.

• When running Disk Management, get the error - failed to connect to the virtual disk Service.

  When I run the Snap on the local server disk management, I get an error message in the status bar: unable to connect to the virtual disk Service.

  Thanks, I have tried these things and nothing has solved the problem.  Here's what I did:

  (a) check the VDS service was manual and failures later per second are 'take no action '.
  ANSWER: Yes to manual and following, second has not changed to "restart the service" of "non-action".
   
  (b) sfc/scannow as administrator
  ANSWER: the System File Checker has found no problem (program reported no problem and findstr/c: "[SR]" on CBS.log doesn't have the list of issues)

  (c) restore to a previous system restore point
  ANSWER: I have tried restore points several more early, each of them failed

• Copy of the virtual disk for use by another virtual machine

  Hi all! How can I copy a virtual disk file to a location for future use by another virtual machine? I tried to just copy the hard, but it did not work for me - the copy is about 1 KB size and I can not add it as a hard drive on another virtual machine. Can someone help me?

  OK, so this client web vSphere that you use, in this case browse datastore doesn't show you the two files.

  Please follow the steps below

  Please go to Cluster & host inventory

  Select your ESXi host

  go to the tab 'Manage'-> settings-> Security-> Service Profile, and then click the button CHANGE

  Start the SSH service.

  If please use WinSCP to connect to your Esxi host and navigate to the folder of the virtual machine as in the screenshot to the suite, I navigated to a folder that is my VM name: Win10A

  and it has a virtual disk, if I want to take the virtual disk of this virtual machine to a different VM, I need to copy the two files that are highlighted.

  the two are to train your virtual disk.

  

  Download these two files and download them to another folder where you second VM resides, then try to tie it with this virtual machine.

• How can I change the size of the virtual disk by default?

  Hello

  At work, we decided to start to allocate more disk space for new virtual machines that we create. and every time I create a new virtual machine, and I pass by the Configuration, the name and location, storage, reviews of operating system and network options. I get to create a disc of the options and the size of the virtual disk is set to 16 GB by default. and then I would need to change before the new virtual machine to a larger number. I thought to myself whence this 16 GB by default is set and is it possible for me to change this value by default for example 30 GB, so whenever I have create a VM I wouldn't need to change this to 30 GB.

  Thank you for taking the time to read this discussion.

  Best regards

  S.A

  It would be a feature "nice to have", if we could set up by default to different operating systems. However, I am not aware of a way to do it. The only thing you can do in a cluster is to create a VM template and clone the new virtual machines from the model.

• VMWare Player installation and Installation of the software in the virtual disk

  Hi people,

  I installed VMWare game in the free Version. I want to use the virtual disk for a Windows XP operating system. I have the following question for my main system (8.1 Windows 64 bit system stand-alone system).

  1.

  I installed a Windows XP 64-bit with SP 2 system. In this virtual disk, I installed a software that needs several software components. I managed to install all the components, but one. This component is WindowsInstaller-KB893803-package x 86 lot. If Intry to install the following error notice appears: "Ce KB893803v2 is for a different hardware platform." How can I make this software to obtain the virtual hardware information (i.e. not information of the current build-in components for Windows 8.1).

  2.

  While I did all the settings in Windows XP SP2 in the virtual disk on 'German' keyboard assignment is American. How can I change this?

  3.

  I have a 64-bit Windows 8.1 system on my computer (I think it said 'Host system'). Can I install a Windows XP 32-bit system in the Ramdisk anyway?

  Please answer in detail. I thank in advance for your answers.

  Kind regards. Mainze

  
  

  Don't worry too much on the OS host and/or physical hardware like handles of VMware Player, which is required to run Supportepar OSes as guests, for the most part, a layer of virtualized hardware.  Windows XP 32-bit should work fine in VMware Player on your 64-bit Windows 8.1 host.

• Consolidation of many to one of the virtual disks?

  Hello world

  I use a XP client inside a Windows 7 host (using 8 workstations).

  In the configuration of my XP virtual machine I previously assigned (of 50 gigabytes) of disk space into separate virtual folders, about 2 GB each, as shown below.

  

  I now want to have a single vmdk file, with the pre-allocated 50 GB of capacity.

  Is it possible that I can achieve this goal, while keeping my VM in tact? For example can I create a second virtual disk, and then use a cloning tool (from the client) BONE to make a copy to the new virtual drive?

  Here, any help will be greatly appreciated.

  Kind regards

  Hello world

  This can indeed be done! Because I started with a scalable, split, virtual disk, there were several steps; Here's the gist of these measures-

  (1) using the vmware-vdiskmanager merge files into a single.

  http://hostilecoding.blogspot.com.au/2013/06/VMware-merge-multiple-VMDKs-into-single.html

  Note: when running this utility do not forget to include the '2' parameter, which refers to the creation of a virtual disk prealloue, otherwise the following steps (use the shrinkvd program will NOT work!).

  Here is a screenshot of the order that worked for me-

  

  (2) add the newly created virtual disk, 'merged.vmdk' to the existing virtual machine, using these installation instructions.

  https://www.VMware.com/support/WS5/doc/ws_disk_add_virtual.html

  (3) remove the existing virtual machine virtual drive

  (4) to start the Virtual Machine (you will probably be asked if you have moved or copied the VM, I responded with "Proposed").

  (Optionally)-rename the virtual disk of "merged" into something else by renaming the files in the ".vmx" and "hard" files.

  (5) using the shrinkvd resize the virtual disk

  http://www.Softpedia.com/get/system/system-miscellaneous/shrinkvd.shtml

  

  Above, note that the first time, I ran the command it failed with the message "ddb.deletable" is the crux of the problem. I just deleted this line in the relevant file "hard" and the command is represented.

  Now, when I boot on my virtual XP I use only 24 GB of space, and I am able to transfer the Virtual Machine to a smaller drive. in this case a 30 Gig old SSD.

  I hope this helps others.

  Kind regards

• How to read the data written to the virtual disk

  I use the following VDDK function to read the Flash disk from VMware

  http://bigchainring.kicks-ass.NET/functions/VixDiskLib_Read.html

  But areas of complete disc playback, including empty spaces. I need to back up only the data written to the Flash disk. It is to save the backup disk space (for example if 126 instant KB is written in 40 GB of disk snapshot, then we read only 126 KB and not 40 GB drive). Please suggest the correct way to read the data written to the Flash disk as well as to reproduce the same virtual disk with the data.

  VMware vSphere API queryChangedDiskAreas() can be used to obtain the data blocks in the virtual disk.

  Steps to follow:

  1. get the beaches of block of data (numbers) using queryChangedDiskAreas() API with '*' as argument.

  2 read the data of the specific blocks by using VixDiskLib_Read()

  3. write to another drive using VixDiskLib_Write()

• Script to export the virtual disk information in a specific format

  Hi all

  First too all the Scripting Guys who I borrowed the code here, thank you!

  Now, I was able to get all the information I want vcenter but I have problems with two of the scripts I wrote.  It is with regard to obtaining information on the virtual disks associated with all virtual machines in the environment.

  I was able to export the data, but I get a line by VM that does not work for the way in which we want to use the data.

  What I am looking for is a csv export with one line per virtual machine that looks like:

  VM number 1, hard disk number 1 name number 1 datastore, path of vmdk number 1 hd, hd number 1 capactity, number 1 hd, hard drive controller number 2 name,... up to 7

• Please help: the virtual disk parent has changed...

  Thank you!

  It is a small desktop application:

  -Dell T410 esxi Server 5

  -a virtual machine, Windows Server 2003 with 2 discs, no fixed size

  I was help this office by managing services and updates on this Server 2003.  I ran updates on Friday and restarted.  When he came I open vSphere and found the virtual machine does not.  I tried to start it and got the error.  So, it seems I may have the CID issue that needs to be corrected.

  I don't have a direct access to this server so I'm remoting with RDS on 2003 VM server and vSphere on the esxi.  Did I make the right diagnosis and is it possible for me to make the necessary corrections to distance or I need direct access to the server?  Everything I've read has files of people editing CID numbers and it seems that they directly access the esxi server.

  Shows the data store:

  hard 'server '.

  The parentCID of the snapshot must match the CID from its parent, as shown in the log file

  "... The content ID mismatch (parentCID f72e60c7! = f05537b3)... »

  Server.VMDK

  CID = f05537b3
  parentCID = ffffffff

  Server - 000001.vmdk

  CID = a2b9ba8b
  parentCID = f72e60c7---> f05537b3

  Make sure you change the file on the host using the vi editor or - if you want to change the file in Windows - use an editor who is aware of the line breaks Unix (do not use Notepad!)

  Once this is done, I highly recommend that you take another cliché before you on the virtual computer. This prevents existing virtual disk files to be modified, so that you can return to this State where you need. After that everything works as expected, consider deleting all snapshots.

  Is there a chance to run ls-lisa from the command line (SSH) in the virtual machine folder and provide the output!

  I ask because I'm a little worried about the timestamp of the hard (May 2011). Depending on the size of the files in the snapshot, it seems that the second virtual disk is not really used by the guest operating system and we could come back manually (by editing the .vmx file) on the resized basic disk (100 GB compared to 75 GB for snapshots) without losing important data!

  If you want to revert manually,

  • delete the virtual machine of the inventory
  • backup and then edit the .vmx file (replace "WEBPDMAPPD_1 - 000003.vmdk" with "WEBPDMAPPD_1.vmdk")
  • Move 3 snapshots in a directory temporary sub
  • Add the virtual machine to inventory
  • create a new snapshot to prevent the current hard files to be modified
  • Turn on the virtual machine

  If everything works as expected, you can delete the snapshot files moved and remove the snapshot created in the Snapshot Manager again.

• VMDKMounter gets error "could not open the virtual disk.

  I have two Win7 x 64 virtual machines running fine with VMware Fusion 4.1.2.  I installed VMDKMounter from VMware 3.1.3 and OSXFuse 2.3.9.  I can ride one of the files hard with VMDKMounter very well, but others told "Cannot open the virtual disk" when I try to mount it.

  The virtual machine that VMDKMounter fails to mount was created by VMware vCenter Converter 5.0 of a physical machine.  The virtual machine that works was created in VMware Fusion 4.

  Of course, the hard I really want to ride with VMDKMounter is he who fails.  No idea how to make so that he can get?

  Well, I see nothing in the disc DescriptorFile which prevents the hard mounted.

  So right now, you can mount other hard files, but not this one, then I have two suggestions...

  It would be to use vmware-vdiskmanager to create a new hard that will not go up and the other would create a new empty hard, then add it to a virtual machine, as well as one that will not go up and then start with appropriate optical disk or an ISO Image containing the appropriate tools/utilities in order to image the drive to the new empty.  I usually use Symantec Norton Ghost for operations like this.  Then maybe a new mounts with VMDKMounter.
