• 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()

• 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.

• 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.

  8 June 14:43:27 hoth [0 x 0-0xe50e5].com.vmware.vmdkmounter [2394]: could not parse the instant string ' / Users/finchr/Documents/VirtualMachines.localized/hoth.univ.dir.wwu.edu.vmwarevm/hoth.univ.dir.wwu.edu.vmx '. 8 June 14:43:27 hoth [0 x 0-0xe50e5].com.vmware.vmdkmounter [2394]: will not be able to take an informed decision, based on partial information. 8 June 14:43:27 hoth [0 x 0-0xe50e5].com.vmware.vmdkmounter [2394]: mount the drive read-only instead. 8 June 14:43:27 hoth [0 x 0-0xe50e5].com.vmware.vmdkmounter [2394]: failed to open the disc: disc encoding error (261993021117)

  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.

• "The virtual disk parent has changed..." "after removing a few shots

  Hey!

  I'm using VMWare Workstation and deleted a few shots via the Snapshot Manager. I used a .vhd Image from the Microsoft Site (Windows Server 2003, x 86). VMWare has created a link to this image at the beginning. I was working on this virtual machine for 2 weeks.

  Now, I have deleted 2 snapshots, including the first snapshot. When I try to start all the existing snapshots the error which is entered in the subject line of this discussion. Detailed error explains that his "cannot open disk 0 - 0000004.vmdk or one of the snapshot disks it costs on.» Reason: the virtual disk parent... »

  How can I access any of the existing snapshots in the future? I read that it is necessary to open the virtual disk images and change the CID of this disk image virtual to who should be the one parent. But how do I edit these virtual disk in windows vista? I have no command line tool that extracts only the first 20 lines of a file so that it will be impossible for me to open a vhdk with 600 or 700 MB. Another problem is that (I don't know why) my virtual disks are splitet in so many parts (I said at the beginning that the virtual disk must be a file, but I think splitet VMWare Workstation it because she had to be converted to .vhd (Microsoft) .vhdk... might be?)

  Here's a screenshot of my file of VMWare this virtual machine sorted by type and sorted by size (for a better overview, I think):

• Unable to create the virtual disk: fault. RestrictedVersion.summary

  Hello

  Im trying to create a virtual disk using the CLI on ESX4i.  The script is:

  vmkfstools.pl - Server 10.190.2.51 - c 20 g d eagerzeroedthick - a free /vmfs/volumes/Internal/test.vmdk

  When the script runs I get error: unable to create the virtual disk: fault. RestrictedVersion.summary

  Can someone tell me why please.  Im trying to create a disk of 20 GB with adapter free with eagerzeroedthick on my internal called storage, (no subdirectory).

  The file system is THAT VMFS 3.33 maximum file size is 256 GB.  The block size is 1 MB.  If it is the block size that is the problem how can I easily change?

  It's in a laboratory, not a production environment.  I need the flag eagerzeroedthick like Im trying to create a passive active cluster node MSCS 2 on a single physical node with 2 machines VMS.

  Thank you.

  If you use the free version of ESXi (U4 and later versions), access to tools like the VIMA API are read-only.

• 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

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

  After a few days of research about this error, I decided that I had to ask for some evidence of your experts to help me recover from this error.

  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 '.

  hard 'server_1.

  'server' - 000001.vmdk

  "server_1" - 000001.vmdk

  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.

• The virtual disk is either corrupt or not a format supported.

  We have a 2008 R2 SP1 VM Datacenter we cannot snapshot.

  A manual snapshot of in the Client vSphere indicates the following in the tasks and events:

  The virtual disk is either corrupt or not a format supported.

  Our NetBackup software is automatic snapshots for VM backups and generates these three errors in the tasks and events:

  Cannot run a snapshot operation
  

  Operation timed out
  

  A general error occurred: VMX protocol error.

  The virtual machine has two virtual disks:

  [vmds-standard: (1) default] outhostname/ourhostname - 000001.vmdk

  [vmds-standard: (1) default] outhostname/outhostname_1 - 000001.vmdk

  Virtual disk files seem to be the usual file names. Instead, they resemble snapshot files or something similar.

  I don't know what is happening. Can anyone help?

  The file names are correct, since there is an active snapshot on the virtual computer. I found a few entries in the log file that we/you can see:

  08:01:25.543 Mar 23: vmx | DICT scsi0:2.deviceType = scsi-disk hard
  08:01:25.543 Mar 23: vmx | DICT scsi0:3.deviceType = scsi-disk hard

  There are some entries of old/orphaned for already deleted virtual disks! However, it should ask the question.

  21:13:06.212 25 March: vmx | In SUMMARY: SnapshotBranch failed: changes, followed by target file already exists (5).

  That's what I think is related to the question. For me, it looks like a problem once with block change tracking, which may have left orphans. What I would do, is first of all to delete all the .ctk files in the folder of the virtual machine on the data store (they will be recreated, only the next incremental/differential backup will take more time). If this is not enough, you can try to disable - at least temporarily - CBT for the virtual machine or remove the virtual machine to inventory, delete the .ctk files and then add it to the inventory...

• cannot resize the virtual disk (vmdk) after successful hyper-v conversion

  Hello

  We are experiencing an environment vSphere 4.1. I have a problem on the Ramdisk resizing.

  We had managed to convert a hyper v VM. Virtual machine operating system is Windows 2008.

  After that, I can't resize the virtual disk (GB in disk options was gray-ed out, even when the virtual machine is power down)

  It's strange

  I have attached several screenshot of the virtual machine.

  Need your advice.

  Thank you

  His grace is on the IDE interface and you can not resize. the only way is to reclone using vmware converter and resize in the wizard. For more information: http://www.yellow-bricks.com/2010/05/28/resizing-your-ide-virtual-harddisk/

• What is the right way to expand the virtual disk and then the OS partition?

  I have a Windows XP operating system in a virtual machine VMware.  I have

  you want to increase the size of the hard drive.  It currently has a 50 GB

  partition on a 50 GB VHD.  I increase the size of the

  50 GB to 100 GB in VMware virtual hard drive.  Then, can I use

  Windows disk management to increase the size of my partition of the

  side OS to use all the 100GB he sees now?  Or will

  corrupt my data or cause a problem as I really need to

  use a third party tool like EAUSUS inside Windows to extend Windows

  on the size of the virtual hard disk?

  In fact the way you describe, resize the virtual disk and then developing the partition are the way to go. But there are some things that you should be

  aware of.

  -If the VHD is on an IDE controller, you may not be able to resize the virtual disk. In this case use the converter. With the converter, you can resize the disk including the partition and - if desired - replace the IDE controller by a SCSI controller.

  -If you have only one partition under XP (that is, drive c :)) you cannot extend the partition with the diskmanager/diskpart. In this case, start your virtual machine from a CD/DVD Vista/Windows 7 in Repair Mode, open a command line and use "diskpart" from there to "extend" your partition.

• the virtual disk parent changed

  I just did something really stupid and hope someone here could help me...

  I have a virtual host named dev4, that has a snapshot created a year ago.  It has several virtual disks, one of them is dev4 - 000001.vmdk, who has a parent disk dev4.vmdk.

  Today I come to create a new virtual machine named dev5.   My intention was to disparage dev4 and use dev5 moving forward, so I want all my data in the virtual disks of dev4 is available in dev5.

  Now, it's the stupid part.  I added two dev4 - 000001.vmdk and dev4.vmdk (one at a time) to the new machine virtual (dev5) and mounted to them (I was running Fedora in two virtual machines).    It's really successful, but then I can't repeat this process and dev4 won't boot either.  "I got the error message was.

  Details: Cannot open the disc "C:\Virtual Machines\dev4\dev4-000001.vmdk" or one of the snapshot disks it depends on.

  Reason: The virtual disk parent has changed since the child was created.

  "

  Apparently the action to add the dev4.vmdk drive to dev5 or mount in dev5 led her to change.  I have a lot of data in dev4 - 000001.vmdk which are not saved.  Is it possible I could get these restored data?  Right now I can not open this vmdk due the above error.    Any help would be much appreciated!

  Sorry Peter - I guess I was kinda hard...

  It's just that in so many cases users who have encountered a problem with the snapshots do themselves more damage by acting in quick.

• VMware Workstation is unable to open one of the virtual disks required by this virtual machine because it is larger than the maximum file size supported by the host file system.

  I'm transitioning from Windows XP (64-bit) on a new computer with Windows 7 installed.  I undertook to VMWare Workstation 6 7.0.1 in the process.  The problem is with a very large RAID 5 volume on the new system.  It's a score of 5.45 TB (TPG and NTFS).

  When I try to start a virtual machine on this volume, I get the message "VMware Workstation cannot open one of the virtual disks required by this virtual machine because it is larger than the maximum size of the files supported by the host file system.".  This is obviously not true.  If I copy the virtual machine to another drive on the system, it starts without a problem.

  Anyone have any ideas on how to work around this problem?

  try to add this line in the vmx file:

  diskLib.sparseMaxFileSizeCheck = "false".

  Maybe it helps.

  VMDK-type do you use?

  monolithicSparse? -C' is the only part type more?

• VMware Tools: Shrinkage of the virtual disks - what is - this intended?

  Hello

  Maybe I'm missing something, but what is the "Reduction of the virtual disks' in VMware Tools used for?  It seems to me that 'reduce the virtual disks' is the only thing that it does not.

  I have a virtual disk in a virtual machine with Windows 2003 Std x 64.  A 'volume' (a partition on a dynamic disk) disk occupies 10 GB on a virtual disk.  The rest of the space on the virtual disk is not assigned.  I want to "shrink" the virtual disk to recover the unallocated space.  But the function "reduce virtual disks" VMware Tools seems to allow me only to "shrink" the disk volume or partition.  I want to reduce the virtual disk.

  What Miss me?

  Thank you.

  Your best best for shrink disk is to use VMware vCenter Converter.  The fret is more than one optimization tool, a bit like a Defrag tool, but will not reduce the size of the disk of the virtual computer.

  Here is a good article
