How instructions on-the-fly are caught in the trap in the VMware hypervisor?

The hypervisor translated all the operating instructions on the fly system and caches the results for future use, exactly how it catches on the instructions of fly?

This is true when you use the binary translation, which is increasingly rare.

The hypervisor has the IDT, so it gets the control every time that the guest of the vectors through the IDT.  The hypervisor also has the SYSCALL/SYSENTER MSRs, so it gets the control whenever the customer uses the syscall or sysenter instruction.  Basically, the hypervisor intercepts all transitions of comments from cycle 3-ring 0.

    You will need to access the data store of the ESX/ESXi host where the virtual machine is running, then you will be able to read the file on the run.

  • How to prevent the VMware Tools reset the size of my text on 4 k display

    Hello

    I use 12 Workstation on a Dell XPS 15 9550 with a native resolution of 3840 x 2160 (4 k).  I was able to move on virtual machines running Win 7 from another system where the virtual machines were running at a resolution of 1920 x 1080.  These virtual machines are now running at 1920 x 1080 on the Dell.  (I did it by using the VM settings > display and set a max and running full screen resolution).  The problem is that the text and icons are displayed at 150% the size. I can use the Win 7 Desktop > resolution to 100% and everything is the way I need it, but when I do this change, VMware Tools appears saying that I need to log out and back in.  If I do this the text/icons are at 150%.

    How can I get VMware Tools to stop the reset of this size from 100% to 150%?

    Thank you.

    Here is the solution:

    > Turn on the virtual machine.

    > Click VM > settings > select view.

    > Uncheck the option scale to display "automatically adjust the size of the user interface on the VM.

    > Disconnect and connect when VMware Tools invites.

    > You can now change the font size in the virtual machine to 100%.

    > Disconnect and connect.

  • Equium - how to replace the HARD drive?

    Hello

    I need to replace the hard drive on my Toshiba Equium.
    Can someone tell me the procedure? I changed it once before, and I remember having to press one of the function keys when I turned on the laptop with the new hard drive installed.
    Should I have the recovery disk when the laptop is turned on with the new hard drive installed?

    Thank you very much

    Tim.

    Hey,.

    You should take a look in your user manual. Sometimes you will find a detailed how instruction replace the HARD disk, but it according to your laptop model.

    If you swapped the HARD drive, you need to reinstall Windows. Therefore, you can take the Toshiba Recovery disk that will restore the initial setup in a few minutes with all the drivers and tools. You only have to boot from that drive and that s all! :)

  • How to launch and use the VMware tools

    After installing 2008r2 as a virtual machine and install VMware Tools, I am unable to open the tools and use them.  I did two days of searching, and I can't find an answer to my problem.    Downstairs is an action I took, but I would appreciate any help from the community.

    Purpose:

    Laboratory at home training and certification.

    Hardware environment: (based on "Chris Wahl" home Build Lab)

    SuperMicro Motherboard MBD-X10SLH-F-O

    Intel Xeon E3-1230 v3 3.30 GHz processor with 32 GB of ram

    Software environment:

    64-bit version of Windows 7 Professional, host operating system

    VMware Workstation 10 with all updates installed with administrator privileges

    VM #2: vSphere 5.1 install

    VM #1: The Windows 2008R2 VM I have a problem with VMware tools.

    I've deleted and rebuilt the two VM three times now, thinking it was my environment somehow.  ESXi 5.1 works although I have not built anything there yet.  I am able to access this part of the laboratory fine of vSphere Client.

    VMware Tools:

    Within the Services of VM 2008 I can see VMware Tools started service, the icon in the system tray notification area and see the files on the C: drive of the virtual computer, but there is no way to open it.

    I followed several links to create a virtual laboratory, but should not be this hard to run a program.  It's my first time that you try to use VMware tools, but I'm following the steps in the lab below install procedures.

    In the middle of the page of "Blog Editor" part 4 "build the ultimate vSphere Lab is where it installs the VMware tool and lowest after restarting Windows Update service I'm stuck to the next step."

    "Open VMware Tools, go to the Shrink ."  Click on the button of the prepare to shrink . »

    ?  How to "open the VMware Tools?

    Now on the path I have searched for and deleted and reinstalled the tools, but always without success.

    Here is a link where I found the following measures to be taken, but it doesn't work either.  The "NOTE" at the bottom, it's something I noticed and made sure was right when I installed the last time tools.

    I even found a link to where you can download the tools separately from the ISO files, and yet, it does not work.  A LITTLE HELP PLEASE!

    http://www.vdsyn.com/Windows-2008-R2-virtual-machine-VMware-tools-shows-not-running-current-after-vmotionsnapshot-operations-randomly/

    So next step that we did was
    1 uninstalled VMware Tools in the virtual machine
    2 restarted the VM
    3. manually deleted/renamed the C:\Program VMware Tools
    4. manually deleted/renamed C:\Programdata\VMware\VMware tools
    5 Rebooted
    6. install the VMware tools
    7 Rebooted

    The issue is not reproducible after the same


    NOTE: Make sure that the virtual computer CD player points to the correct image.  I found it always go back to the windows 7 iso image on my C: drive from physical machines to where the image 2008r2 was on drive E:

    No need to reinstall again. You're not missing something. VMware has changed the VMware Tools tray and removed options that were available in previous versions. Take a look at for example experience front of VMware: The VMware Tools GUI is gone - now what? with some information about this change and the replacement of the command line.

  • How to refine the configuration of Vmware server on windows host

    Hello

    can someone explain how to refine the Vmware host windows server edition?

    Hello

    First, you decide what you want to use the VMWARE server.

    If you want to use vmware server for only to keep the plane comments at end of test system administartion, during the installation of VMware server you will need to customize your installation.

    In the Customize installation disable the Modules Perl script which are used for development purposes, after installing the server, go to services & disable services unwanted, assume that you use no DHCP & NAT, then disable these services. In doing so, it will save the memory & performance increase of you host mechine.

    When you create your mechine comments try to reduce unwanted devices, how to remove the floppy drive if you don't want to use in the mechine comments. like this, try to reduce the additional devices you use rarely, if you're runnin server edition comments mechines, then try to reduce you is display resolution, which will give a good performance.

    Kind regards

  • SCSI driver is missing in the virtual machine. Driver is missing in the provided website. Instructions on how to install the driver (once you find) are missing.

    I get the text following error encrypted every time that I boot Windows XP in VMWare Fusion, since I've upgraded to version 4.02 a few months ago.  So I upgraded to version 5.02 hoping the error would go, but he didn't.

    When I try to start it, it says "he has at least a virtual SCSI device installed on this virtual Windows XP computer.

    Windows XP does not include the drivers for the card SCSI BusLogic VMware Fusion uses virtual SCSI devices.
    To use these virtual SCSI devices, install the VMware driver in the virtual machine. "Download the driver of"http://vmware.com/info?id=43"."
    Once I have to dismiss the message, everything seems to work properly.  How can I make this message disappear?

    I tried to go to the useless link that is provided (http://vmware.com/info?id=43), but it takes me just for a general download for all VMWare products page.  Then I tried searching for "SCSI" but it does not have the driver, I'm supposedly dedicated research

    After doing a bit of searching around, I finally found a driver called "vmscsi - 1.2.0.4.flp ', I connect to my virtual floppy drive.  Once I did, my virtual machine wouldn't boot (I get the error "NTDLR is missing.)  I then unplugged the virtual floppy drive, and now my virtual machine starts again.  I then re-connected the drive floppy and discovered the following content:
    Disk.Tag
    Txtsetup.OEM
    vmscsi.cat
    vmscsi.inf
    smscsi.sys
    OK... Now what?  No installer?  What the hell am I supposed to do with it?  I tried a double click on all of these files and have no significant results.  When the pilot is supposed to go?  No instructions? -What VMware calls "support"?

    The VMware Tools GUI has been removed because it has now integrated with the Virtual Machine settings, however you can still use the command line.

    C:\Program Files\VMware\VMware Tools>vmwaretoolboxcmd help
    Usage: vmwaretoolboxcmd  [options] [subcommand]
    Type 'vmwaretoolboxcmd help ' for help on a specific command.
    Type 'vmwaretoolboxcmd -v' to see the VMware Tools version.

    iCloud does not delete your files even if you lack storage. She stops just to download new files to update your existing backups. You can delete files by yourself if necessary.

  • Why I can not connect on the accounts of Firefox to put in place the synchronization? FF30 + keeps telling me how please enable cookies; cookies ARE enabled, already tried Safe Mode.

    Exactly what it says on the Tin.

    Why can't I connect to Firefox accounts to set up sync to my laptop? FF30 + keeps telling me how please enable cookies; cookies ARE enabled, and I already tried Safe Mode. This has happened since the new Sync has been set up, so I think that nearly 30 FF. I'm now up to 34 FF version and it still does not work. I was not able to sync from the "update".

    Problem #1: Going to about: accounts and clicking the Get Started button Blue opens a blank screen. It's not even a prompt on the cookies. It's just empty. Screen attached.
    It comes from before the modules are disabled. If they are disabled in Mode safe, we go to the #2 problem.

    #2 problem: I've skimmed a thread (https://github.com/mozilla/fxa-content-server/issues/1017) and I tried connecting to sync through accounts.mozilla.com instead, but if the screen does not turn white while the modules are always enabled, "Enable cookies" warning are as far as I can get. Go to about: accounts in Mode safe mode gives the same result. I deleted all my cookies and my cache, FF restarted several times with and without active modules and still nothing. I browsed this forum of support for similar issues, and while other people have the same problem, no other threads have been solved yet. Several later versions of FF, it is far too long for this question still unresolved... Screen attached.

    I know where the Firefox Cookie Manager, and I have enabled all settings. I was even able to third party cookies (even though I shouldn't really because they are unnecessary). No difference. Screen attached.

    I looked into: config and looked up the word 'cookie' in names, but even this is useless to me since I am not a programmer and so ignorant of what mean really all of these parameters. Screen attached.

    I'm at the end of my rope here, guys. It has been for months. A year. Maybe more than a year. I don't even remember. I just got a new camera and I don't want to add all my Firefox information one by one. It doesn't seem to be a way to contact Mozilla directly, so... Someone help please...

    Ensure that you allow cookies for the domain of the accounts.firefox.com if you are not allowing cookies generally or use the cookie setting 'Ask Me '.
