Use of the virtual machine / machine is safe?

I have windows 8.1 pro I want to use operating systems diferrent/test I use virtual box to install the OS on my laptop, it will be useful for me to install os without data lost, but I noticed that when I run the VM my system's struggle

can I use the virtual machine on my laptop without care or stop using it please help



It is very good for the material.

But follow the steps above, then you don't take too much of your main operating system resources when you install virtualbox.

  • Alarms / opinion on the use of the virtual machine JAVA Perm Gen

    Hi team,

    I need to configure alarms / Notification each time that the use of the virtual machine JAVA Perm Gen is greater than a threshold value. I don't see all the default rules / corresponding to Perm Gen registry variables.

    Could you please enlighten us in how I can achieve... ?

    A screenshot is attached for your reference.

    Kind regards


    I tested it after the previous message which was released indicating that you have an error, the nice thing about Foglight is that it allows to see the measures that exist (as you noted the names are a bit different in this case as the example of the JVM) and it also gives you a test button to validate the expression) , don't forget to make sure that she only appliese to the things that have names like Perm if you want it calculated only for generations of perm.

  • Disk space used by the Virtual Machine

    I'm under VMWare Fusion worm / 3.1.4 on a MacBookPro 2010 with Windows XP Pro installed.  In My Documents, there is a folder called "Virtual Machines".  It has a file in it, "Windows XP Pro 2.vmwarevm".

    The problem is that this file is 121,95 gigabytes!  Nearly half of the size of my hard drive.

    Question 1.  Does this make any sense?

    Question 2.  This file size can be reduced to something reasonable?

    Thank you!


    According to the information of the beam support Virtual Machine has 8, not 7, Snapshots.

    Without a support package for now present the only other suggestion is to delete all the snapshots, and then reduce the virtual hard disk of the applet of control panel of VMware Tools in Windows, and then Clean Up drive from the drives Panel in the settings of the Virtual Machine.

  • Generate the CSV file to the virtual machine by using get-stat statistics

    Hi all

    I put my VC for taking samples every 5 minutes for 3 days.

    I would create a PowerCLI script that I can then run on an ad hoc basis to connect to my VC and to get the details for ALL of the virtual machines that are managed by this CR and fill in a CSV (c:\foo.csv):

    • Name of the virtual machine

    • The ESX VM host is currently sitting

    • total number of virtual processors assigned to VM

    • total memory allocated to the VM

    • memory active average used by the virtual machine in the 3 days using samples of 5 minutes

    • average mhz CPU used by VM spent 3 days using samples of 5 minutes

    I have attached a sample file XLS of CSV output should look like.

    If anyone can give me a code to achieve or get on well on my way, I would appreciate it a lot.

    Kind regards


    OK, so what you want is something like this then?

    Get-VM | Where {$_.PowerState -eq "PoweredOn"} |
     Select Name, Host, NumCpu, MemoryMB,
               @{N="Cpu.UsageMhz.Average";E={[Math]::Round((($_ | Get-Stat -Stat cpu.usagemhz.average -Start (Get-Date).AddHours(-72) -IntervalMins 5 -MaxSamples (12) | Measure-Object Value -Average).Average),2)}},
               @{N="Mem.Usage.Average";E={[Math]::Round((($_ | Get-Stat -Stat mem.usage.average -Start (Get-Date).AddHours(-72) -IntervalMins 5 -MaxSamples (12) | Measure-Object Value -Average).Average),2)}}

    I think that the issue that you have with the missing stat might be to do with your logging levels in VC, if these are not set correctly it will not save these stats for this period of time.

    What do you get if you do a simple:

    get-vm "SingleVM" | Get-Stat -Stat cpu.usagemhz.average

    If you found this information useful, please consider the allocation of points for correct or helpful.

  • How the snapshot of the virtual machine?

    Hi all

    We use the VDI in our Organization. We use Linked clones.

    I have to recompose all pools each week. And to recompose some users will be connected to the virtual machine. So, generally, I select wait for logof users recompose. But some of the virtual machine are not getting laid, even though the disconnection of users due to the task request has expired error. And we manually recomposing machines.

    Is it possible to know the snapshot, used by the virtual machine to the pool in the blink of an eye (i.e. What snapshot it uses if a new or old)

    Otherwise, I have to check with each virtual computer and details of the snap of this virtual machine manually. We have 900 such VMS in my environment.

    Thanks in advance.

    Go to the inventory pool, - 'See composer details' and sort on the column "last image".

  • Evacuation of the virtual machines before maintenance mode

    When ESX is placed in maintenance mode - it should give you a vmotion option functioning of the virtual machines on the other hosts in the same cluster?  Or it only move down vms to other hosts?

    Thank you

    DRS is your friend here, ensuring that VMS are evacuated.

    If you are unable to vMotion VMs manually from the host, the y is unable to escape during operations in Maintenance mode. The host will therefore go not in maintenance mode before having been involved and sort the vMotion.

    Most often, CD-ROM etc are involved here, but validation of vMotion also includes such things as the availability of resources and port groups (that is, if a group of ports corresponding to that used by the virtual machine is not available on another host in the cluster that has the resources available, the vMotion will not pass validfation and the virtual machine will remain on the host of 'Maintenance Mode').

  • IP not set to start the virtual machine

    Environment: ESX 4 server, hosting VMware Studio 2.0 (final version), will deploy device created in the same ESX host.


    I was not yet able to determine if my wait will not, but I expected that my VM would be marketing it would have an assigned IP address already if I finish the network settings section in the build settings. But when I start my VM, it starts with IP =

    I'm going to network Type = static and by filling in all the details for the IP, mask subnet, gateway, DNS 1 and 2. It seems that they are used when the virtual machine is in 'construction' on the host, but I'm not entirely sure about this.

    In the OVF IP assignment settings, I tried selecting OVF environment, but have not set of OVF properties (I don't think that this should be mandatory if I am already addressing in the build settings).

    After construction, into my vSphere Client (ESX4), I chose the file & gt; Deploy the template OVF... & gt; Deploy from URL and paste the URL of the virtual machine built recently. I start the virtual machine and watch the console screen boot and load the operating system. IP address is never assigned and the console device is displayed with IP =

    I then have to connect with the image, manually assign the IP settings and then everything works. I expect this happen at boot time so that my firstbootscript can take advantage of the assigned IP address.


    Maybe I go about it the wrong way, but my usecase is as follows:

    Build a VM & gt; Distribute the VM on end user & gt;  end user deploys on ESX and chooses address IP & gt; end user boots VM for the first time & gt; firstbootscript runs automatically

    Am I missing something? Can I have different expectations about how IP assignment is supposed to work? I read about IP Pools, but this isn't an option in my vSphere Client.

    Property of the FVO is the best option to set an IP address.

    Long back for Linux OS, I have written a shell script to set the IP address and the hostname in firstboot Virginia you can try this for your going here is the link for the same thing.

    In the OS from VMware Studio tab you can paste this script in the script firstboot.

    First of all, please run this script manually and then use it in VMware Studio firstboot.

  • Size of the virtual machines on the local data store

    What is the best way to determne the (total) disk space using a virtual machine? We have several virtual machines on local data warehouses and would like to estimate roughly how much disk space to the total number of virtual machines use to caculate how much storage SAN, they will consume. Is there an 'easy' way to socket this information?

    The most accurate way would be to calculate the total space used by the virtual machine files in the data store.

    Connect to the service console

    Navigate to the vmfs volume

    Navigate to the vm folder


    This will give you files for this particular virtual machine related to the amount of disk space used by all the vm


  • Could not power on VM: no space is available on the device: cannot power on the virtual machine.

    VMware esx ei, 3.5.0 123629

    compared to the virtual memory?

    Thank you



    Memory reservations are defined based on VM by VM.

    You can allocate more memory to the virtual machines you have in your host (it's not really a good idea to go crazy with the overcommitment of memory, but some level of excessive pressure is used in general).  Memory applied to your VM resources are shares, bookings and VMkernel Swap limits.

    Just to illustrate:

    You allocate 8 GB memory to a virtual computer.  If you take all the parameters by default, ESX will allot a 8 GB VMkernel Swap file in the base directory of your VM (it will have the extension ".vswp") this VMkernel Swap file is a safety net.  Your virtual machine, at this stage, can consume up to 8 GB of memory If physics is available from the host.  If the memory of your host is overcommitted, some of the available memory 8 GB could be allocated on 8 GB VMkernel Swap file.

    If you set a reserve of memory - 2 GB - this means that the vmkernel will still award the first 2 GB of memory used by the virtual machine to the physical memory.  This is not means that the 2 GB of memory reserved is carved off the coast and completely dedicated to the virtual machine.  This means that the vmkernel offers up to 2 GB of RAM to the VM when and if she needs to use it.  It is a guarantee that the memory will be available upon request.  Because of this guarantee of the VMkernel, VMkernel swap file only has to make sure that the 6 GB memory is satisfied (4 GB total less the 2 GB reserved), so the VMkernel Swap file is only 6 GB in size.

    Actions are a mechanism for prioritization and limits are a cap on physical memory ever allocated to the VM.

    You can set up any number of memory for the virtual machines that you want - frankly, overcommitment of memory for ESX is a very good thing, but you must be vigilant about watching your systems if approve you.  If you have 64 GB of RAM, and you only configure your virtual machines to use total 32G, then you lose 32 GB of RAM.  If you allocate, say, 96 GB of RAM (total) to your virtual machines, then you look at a 50% overcommitment.  What to watch in overcommitting memory is application performance (and more importantly - perception of the user of this performance) and also the memory ballooning and VMkernel Swapping activity.  Those who can both will be in graphics performance in VirtualCenter.  I would recommend reading the Guide to management resources for more details.

    Hope that provides an overview.

    Thank you

    VMware Fusion: Professional Version 8.1.1 (3771013)

    When you run a VM guest in headless mode I can't use vmrun to get IP clients. If I eventually bring to the top/start the merger GUI, the command returns the IP address as planned. It is always reproducible.

    $ vmrun -T fusion start "path/to/MyVMs.vmx" nogui

    ... Start the VMware GUI and ensure the VM's console window is open

    My requirement is after power, smart card reader can stay connected to the virtual computer with the already installed driver and the smart card.

    Kindly help with this problem.

    Thank you!!

    Dear all,

    I had a work around for this problem. By adding "usb.autoConnect.device0 ="0xVID:0xPID"" this statement to the VMX file, solves this problem, that is, whenever the VM is wake-up by clicking on the link CV or using vmrun commands, it connects the unit in question automatically and it is charging correctly with his driver. Obtaining smart card detected after sleep\hibernate with no problems.

    VID & PID is respective ID of the device that can be seen in the properties of the Device Manager "Device Instance path".

  • 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.
