You can edit vmx file while the virtual machine is running? And is it safe?

You can edit vmx file while the virtual machine is running? And is it safe?

Hello

Moved to the forum of the Virtual Machine and the guest operating system.

If you edit the VMX while the virtual machine is powered on change is not levied until the power off then power on (not reboot) and there is a good chance that the change will be deleted when turn you off the system. So it is not safe to do so.

  • You can synchronize a file to the virtual machine on two macbook pro

    I have 2 macbook pro I synchronize files with every night. I want to keep the file of the virtual machine the same on both machines. If I run VMWare Fusion with this file to the virtual machine on a single machine, quit VMWare Fusion and then synchronize the file tonight, the other machine will be able to open it without additional configuration steps? Thanks for any help you can give me.

  • Path to the file on the virtual machine

    Hi people

    I am aware of VMRUN and would use call programs on the virtual computer and move files between the host and the guest.  I don't know exactly what it does good, nor how these virtual machines are actually structured, so I would like someone to clarify for me if it is even possible to have a host path to a file on the client VM.

    For example, I use scripts from my Mac that do a lot of editing on the side of the virtual Windows machine - is there is a way, I can use to refer to and modify a file on the virtual machine without using VMRUN.

    Thank you very much!

    Mirroing is a little difficult, I don't think that anything that is either duplicated with shared folders.  What happens is the Windows to the Documents, music, path is set to a UNC path (vmware-host\), which is served by the VMware HGFS file system, a mechanism for sharing private with OS X.  In OS X, just the files live in any directory is shared.  But that's what you say, a place with several shared paths.

    For SMB sharing, sharing so once mounted on your Mac, OS X uses a SMB client to Yes go on the network to access files in your guest VM files standard Windows.  All traffic is host only, unless the virtual machine is filled and you use the Wifi connection, in which case the traffic can "bounce" the point of wireless as a jump.  There are ways to optimize the network path, so all traffic is strictly host only.

    I have not benchmarked HGFS v. SMB, but there is a "tax" anyway compared to the opening of the VM file on its file system local.  For your use case, it is probably useful to check the two options.

  • Is it necessary that the guest OS to support SSD if the file of the virtual machine is placed on an SSD?

    Dear,

    I have a plan to set up a file of the virtual machine on an SSD. The host system is windows 10 (on an other SSD, I'll use 2 SSD), it should support the SSD very well.  Then comes the question: should I also install an OS that needs support also guest SSD?

    My opinion is it does not matter since the disk i/o operation is made by host operating system, it is the host operating system which finally determin whick block data will be published (optimization of the disk).

    Am I wrong? Thank you.

    Sorry for the enigmatic answer...

    In your case, the answer is Yes: he cares about the type of media, while the virtual disk is a vmdk (virtual material treaty) and placed in an SSD.

    There are a few cases where you might use a physical disk directly to the virtual machine (called peripheral raw disk or RDM in vSphere environment).

  • Not able to add the snapshot file to the virtual machine

    We have Win 2003 virtual machine running on ESXi 4.0.0 261974. The virtual machine has two vmdk files. We had taken the snapshot a few days back and today by mistake, we have removed one of the vmdk (DB - srv - 000001.vmdk - snapshot file). Now, we are not able to add the snapshot file to the virtual machine. When tried to add the existing vmdk, it displays only the source disk (DB - srv.vmdk). Please, help us to solve this problem.

    The GUI allows only adding the base vmdk. To add the Flash disk, you must manually change the vmx file. Registrations for the formerly removed virtual disk could still exist in the vmx file with... .present = "FALSE". After changing the vmx file you must reload the configuration. To do this, remove the VM of the inventory and add it back again (right-click on the vmx file).

  • Need help updated the VMX file on several Virtual Machine

    All,

    Can anyone help with a problem I'm having?  Here is a brief explanation of what is happening and what we need to solve.

    Recently we found out that we need to add a line in the file VMX of several virtual machines.  In the past, I was able to do this, but would have cold start the virtual machine for the changes to take effect.  Starts cold won't be a problem, because we can program it.

    However, no one knows a way to add this line in the file VMX virtual machines in a cluster.

    Here's the line I need added:

    Devices.hotplug = "false".

    Here is a script that was used earlier (esx 3.0 days) to keep the VM tools updated on reboot.  At this point, if the virtual machine has been turned on, this change could not do through the UI.  However, this script worked to update the .vmx file and then we have cold reboots for the changes to take effect.

    Get-viserver - < Server > - < user > - < password >

    $viview = get-Cluster-name NOMCLUSTER | Get - VM | foreach-object {get-view ($_.ID)}
    $viview | {foreach-object
    $vmConfigSpec = new-Object VMware.Vim.VirtualMachineConfigSpec
    $vmConfigSpec.Tools = new-Object VMware.Vim.ToolsConfigInfo
    $vmConfigSpec.Tools.afterPowerOn = 'True '.
    $vmConfigSpec.Tools.afterResume = 'True '.
    $vmConfigSpec.Tools.beforeGuestStandby = 'True '.
    $vmConfigSpec.Tools.beforeGuestShutdown = 'True '.
    $vmConfigSpec.Tools.ToolsUpgradePolicy = "UpgradeAtPowerCycle".
    $_. ReconfigVM ($vmConfigSpec)
    }

    The exact script can be found in Disable HotPlug

  • Loading file to the Virtual Machine by using an external USB drive... Please help

    We have an environment that we would like to import and create a virtual machine. The files are on the external 1 TB external hard drive USB puppy with NTFS. The files are approximately 430 GB. I tried almost all the options to get the files to the HOST that is running the server ESXI 4.0.

    Whenever we tried to get the files using the USB drive and Vsphere client connected to a local computer running windows on the ESXI 4.0 Server somehow transfer stops after a while. Some time around after ro possibly around 250 GB 200 GB. So far, we are not able to get the hard master file that occupies about 430 GB in the ESXI data store.  We also tried the third "Fastscp" software to transfer files to the ESXI host, but we had the same problem that the transfer stops at some point.

    Another option that we tired was to start a machine with Linux live CD and USB directly attached to this machine. As the Linux version was newer USB NTFS partition hard drive has been detected without installing any NTFS disks. We have mounted the drive USB on this machine and exported the mount point. In the ESXI server using CLI not supported (Alt - F1) we were able to ride the point of editing exported and tried to copy the files to the folder main datastore but same problem the transfer stops after a few hours sometimes even near 300 GB.

    Y at - it somehow I can bypass the file transfer by using not not the network, which means that if we reach directly the USB key to the ESXI server machine does not recognize it (using Alt - F1 not CLI) because it is partitioned into NTFS. I read that ESXI only supports FAT partition.

    We also tried to start the machine running ESXI server with the latest versions of Linux, in this case, we were able to mount the USB drive directly, but because ESXI stores files with VMFS partition we couldn't mount this partition in linux.

    Could you please recommend any solution to get the files the server ESXI 4.0?  Is there a way to allow us to start the EXSI with Linux server and can mount the partition VMFS use third-party drivers? OR what you would do. Advice would be nice.

    Welcome to the forums - using the vSphere client should work - block of what size did you use to create your VMFS data store? If you left it at the default of 1 MB, then the bigger file, you can copy that VMFS datastore is 256 GB - you'll need to create the data store with a block size of 2 MB which will allow you to create a file upto 4 MB or 512 GB keast and a size of 1024 GB.

  • Script to change the name of the file to the virtual machine and its associated files

    Hello

    I'm looking for a script to change the name of the virtual machine in virtual center and also change it has associated file names in the data store to match file name of virtual machine. But the vmdk file will contain a descriptor which maps the - flat.vmdk file. So not sure that we can achieve this through a script.

    Thanks in advance!

    Not really as much as I know.

    The advantage of the svMotion is renamed it the files (.) VMX, VMDK,...) For you.

    The only alternative would be the command line. See Duncan Howto: renaming a virtual computer.

    With the help of the plink.exe tool which could possibly be scripted.

    or do I have to stop the Virtual Machine first and then download?

    Chris

    If you want to have a consistent state, Yes.

    If you just need a consistent state to the accident, you can create a snapshot, download the base vmdk files and then validate once again the snapshot operation.

    You cannot download files in use (except the read-only).

  • Cannot download the files of the virtual machine for the data store

    Hello

    I get an error message "connection to the server timed out" while I'm trying to download the files from the virtual computer from the data store.

    Although the ESX and my laptop are on the same network, I get this error message.

    Please let me know if I need to take care of something.

    Thank you.

    I think that hard & .vsmp be used & locked is why you are unable to download it. Try to download the file, whereas the VMs system is turned off
