Prepare to use a physical disk or an unused Partition

VMWare Workstation version 8.0.4 build-744019

SE host: Windows 7 64-bit

Host HW: 8 GB, Intel Core I7-2670QM 2.2 GHz (4 cores, 8 wires)

I have a 512 GB SSD (OCZ Vertex 4) in my machine, bought specially to speed up the construction process of the cores for embedded systems.

I installed Windows 7 64 bit on this SSD and booting from it. I shrunk the drive in Windows 7 diskmanager and released a 100 GB partition to use for a virtual machine running Windows 7 32 bit.

Training VMWare this 100 GB on disk 0 partition format the easy installation. The Windows 7 installation screen displays this error in step "copying files...". ». The error is 0 x 80070057.

The States of using VMWare guide (on page 14, under the title 'Prepare to use a disc or unused physical Partition'):

On Windows Vista and Windows 7 hosts, you cannot use the system partition or physical disk that

contains, in a virtual machine.
I just read that I can't do what I'm doing? I can't use a partition on the physical disk that is used to start the host for a virtual machine operating system?
What is the technical reason for this? Is this something that will be possible in the future (or even now with a workaround) or is it something that is technically simply not possible?
The reason for me trying to create a virtual machine that has direct access to my SSD is to speed up the virtual machine. I use it to build kernels. Build a kernel 'natively', so outside of a VM, takes 5 minutes. The same core within a virtual machine of construction takes 30 minutes, and it's on a virtual machine that has files of virtual disk it's on this same (very fast) SSD.
Is there another way to speed up my built inside the virtual machine? The bottleneck is disk access. It's just terribly slow in the VM and lightning fast outside.

I hope someone can give me some advice! Thanks in advance!

You can only assign physical drives in a virtual computer with a crowd of Win7 so player set 'offline '.
Otherwise, you will encounter problems just after starting the virtual machine - the host then banned access to training and the virtual machine stops

Of course, you can NOT set the drive system 'offline' on a host with a single disc.

The performance of a physical disk and a preallouee vmdk should be almost the same.

  • Directly using a physical disk without virtual file system?

    I wonder if it is possible to directly use the physical disk with VMware vSphere Essentials Kit and will be that this increase in the performance of MS SQL database if located on this topic over on the virtual file system?

    Yes, you can use RDM with vSphere Essentials. RDM may or may not be faster, and many consider it's a wash. It would be interesting to test it for you, but don't assume that you will get performance much better with a vs the other. RDM can also complicate things like backup strategies.

  • How do you use a "physical disk" like a HDD in vmware fusion

    In the Linux Version of VMWare Workstation, you can select "use a physical disk" by example/dev/sda

    allows you to run VMware from one installation of windows on a real disk, or use this drive

    as a secondary in your vmware session drive.

    In Fusion, however, I can only choose images of floppy disks and not physical drives hard.

    Is there no workaround solution to this merger? Will be the feature that is in the Linux version of

    Workstation never attend Fusion?

    Thank you

  • Use a physical disk?

    I'll install some VMS soon to a SSD drive, the server on which the VMs will be there will be two of the most recent Intel 34nm SSDs, the size of 80 GB. I thought that I could choose the option to let the virtual machines have a direct access to the physical disk, but then I started to wonder if it would cause problems with multiple computers on a single disc. So my first question, does anyone know if there will be conflicts of two virtual computers that have "direct access to the local hard drive?

    Also, when you select the option "use physical drive", is still a single virtual disk created on this disk file? Or he writes all the individual hard disk as if it were a BONE regularly installed on the drive?

    My last question is probably a little more complicated for you all, as he considers how solid state drives works. SSD drives have a limited number of write cycles, normally, for companies, servers SLC based drives are used and life is not a problem. MLC readers become better and with lower usage, that this server will get, life expected to be good for 5-10 years on each disc. Now VMWare creates a single virtual disk file that is written to disk, when changes are made to the virtual machine to the operating system, these changes are then written to the virtual disk on the physical hard disk file. So what I was wondering is when changes are made and this virtual disk file has a change to it, how these changes get will write for the reader in solid state? Because if it rewrites the file of virtual disk to the same cells on the disk then these cells will wear very quickly while other space the disc is still brand new. If the file will be written to a new set of cells? Or will be written only the changes to the drive, and even if it's a single file changes will be written to a completely different sector on the drive?

    Joakim - I don't trust gross in anyway records when you use 'partitionedDevice' and the logical partitions / extended.

    In most cases, I have seen that this creates problems.

    But having more than one primary partition is ok

  • Can I use my physical disks in VDI deservi PCOIP?

    Hello

    in the past, it was possible to use the physical computer drives when I am connected to the VDI with additional RDP Protocol as a hard drive.

    Now, with PCOIP, intercommunication printer function works but not access to readers.

    It s very important for us to share data between computers in our field crew and the virtual machine that is hosted at Headquarters.

    The setting of 'file sharing' in the VMware tools is enabled.

    Does anyone have an experience about it?

    PCOIP not drive remapping as RDP has done.   An alternative would be to use a computer connection USB storage device and use the USB view redirection functionality.

  • 12.04.01 Ubuntu x 86-putting in place a virtual Windows XP machine to access the physical disk

    Dear community,

    I'm new to VMware Workstation, but progressed in computer science.

    At first, I want to give you a brief introduction of my system and my goal.

    HP ProBook 6550 b (System with Intel Core i5 processor Intel-based)

    The HARD drive access mode: S - ATA AHCI

    Operating systems: Windows 7, Ubuntu 12.04 x 86, Ubuntu 12.04 x 64

    Boot Manager: GRUB2

    VMware Workstation (trial period) to 9.01 Linux x 86

    Goal: install MS Windows XP Professional with physical disk access several partitions on the hard drive local

    The installation of VMware Workstation 9.01 on my system Ubuntu 12.04 x 86 worked perfectly, without any error. Large.

    I was able to set up and run a Windows XP VM standard by creating a new virtual disk , following the Nice Wizard.

    It was just to test, but just after I tried to configure the same OS as a virtual machine using a physical disk (for advanced users) to directly access a local hard drive.

    Also, I selected "BusLogic (recommended)" on the choice of type of I/O controller.

    As a device, I chose the HARD internal laptop drive and used two individual partitions (the real partitions on my HARD drive I wanted access within the virtual machine).

    These partitions have been preformatted with NTFS (and not have been mounted in my Ubuntu).

    However, I was not sure if Windows XP has been will be installed on one of these partitions.

    The turn on/off the virtual machine to install the OS, I got the message following (msg1):

    "You are using a SCSI drive. Performance of dual-boot SCSI physical drives are poor. The installed operating system could not start correctly in the virtual machine. However, the physical SCSI disks work normally so exclusively in the virtual machine. »

    Just after the message following (msg2):

    "If you dual-boot a native Windows installation, problems can occur when attempting to start your system in VMware Workstation." For more information, see "http://vmware.com/info?id=128". "
    Click OK to continue, Cancel to power off.

    And finally this (msg3):

    «An error has occurred causing a virtual CPU go into the stop State.» If this anomaly had occurred outside of a virtual machine, it would have caused the physical machine restart. The stop State are accessible by properly configuring the virtual machine, a bug in the guest operating system or a problem in VMware Workstation.
    Click OK to restart the virtual machine or Cancel to turn off the virtual machine. »

    I cannot explain the last error message and don't know what to do.

    After specifying msg2, I found information about possible problems in dual-boot environments, caused by different drivers for the IDE controller.

    So I tried to change the access mode to S - ATA AHCI HARD drive to S - ATA IDE in the BIOS to solve the problem.

    Unfortunately, I have had no success on this operation, because the error message appeared again, once I restarted the VM.

    Sorry, but I have no idea what goes wrong.

    In fact, I don't know what VMware workstation wants to do, when you install the system on a disc/physical partition to have direct access to the local hard disk.

    Because I don't see even the first screen of Windows Setup, there must be something wrong.

    Underlying product system issues and if it's a primary or logical partition?

    Need a complete unformated HDD?

    Only selected partitions are accessible within the virtual machine?

    Is the system installed itself on the selected partitions?

    Maybe some experienced users can help.

    Your help is welcome!

    Thank you.

    stanni

    First I use a raw disk to install Windows XP from a virtual machine, but if I had an existing installation, I would add the partition as a raw to be executed with a VM disk.

    Here's what I'd do...  Install Windows XP to a normal file based virtual machine, and then add a second disk as a raw disk with the partitions you want to join.  That's assuming that you really need not where what to start Windows XP natively and the physical partitions that access are used for data.  Also if need be add the raw disk as IDE.

  • Physical disk with VMPlayer?

    I just downloaded and installed VM Player on a Windows 7 computer.

    I'm trying to get him a physical disk that has Windows XP on it, but I don't see a setting in the drive of the VM to do this.

    Did I miss something or I need to upgrade to the full version?

    Thanks in advance.

    Am I missing something

    When you add a hard drive of the virtual machine, you must select "Use a physical disk (for advanced users)" and note the last part "(pour les utilisateurs expérimentés) '!"

    You must also at least remove the drive letter for drive in Windows 7, before she mounts to VMware Player.

    or I have to upgrade to the full version?

    VMware Player, either for Windows or Linux, is a full version of himself he and does not come in versions of function of different type in itself.

  • The available physical disks is not refreshed.

    I very often use the physical disk option when creating a new virtual machine. The list of available devices will not refresh and I have to manually go to the command line and to find the corret device and then manually enter the device. (Linux Xubuntu 11.0)

  • 3 physical disks in 1 TB in RAID 5 with only its 1 TB usable space incorrectly? Using a Dell PERC 6 / i controller.

    We have a server Dell PowerEdge with a PERC 6 / i controller. There are three physical disks for 1 TB. I created a RAID 5 array, but it seems that there is only 1 TB of usable space after you initialize the virtual disk RAID 5.

    What is wrong? I Googled what should be the size, and I think we should not 1 TB, 2 TB of usable space?

    Too bad. It looks like the physical disks are 500 GB in size, which makes sense.

  • Use of the disk Windows 8 Pro Hyper-V host to 100%

    Hi all

    I'm puzzled. I have a Windows 7 Pro VM a Windows 8 Pro Hyper-V host. When I start the virtual machine, the use of the disc on the drive that it is installed on goes to 100% (on the host). The entire disk, RAM & CPU usage seems normal on the host. The only symptom on the host is extreme latency when I click on things (!).

    As I said earlier, the host is running Windows 8 Pro. He has three physical disks - an SSD that the operating system is installed, and RAID two arrays totaling 18 to each. He has a physical processor, 6 hearts w/hyper-threading. 32 GB of RAM.

    The virtual machine is the only VM I allocated 16 GB of RAM w/dynamic RAM active I allocated 8 cores to it. The OS is installed on a virtual drive of 500 GB. I hung a second virtual disk of 4 TB (TPG), but it is currently offline. I thought maybe it was the problem, but the use of the disc is always maxed out at present. The only other thing I've tried, it is true that as a long-shot, had to change the location of paging on the other empty disk (on the host). That had no effect, either, and I will probably put it when I can. As I type this, the VM is restarted after installing Hyper-V integration services and an update of Windows (including SP1). This will probably take a while...

    Any thoughts are appreciated!

  • Fusion Pro 8 still requires the administrator password to log raw physical disks at startup

    I'm 10.11.3 El Capitan server running in an instance of VM Fusion 8 running on a 10.11.3 host El Capitan.

    For performance reasons, I connect Raw / partitions of physical disk using the links generated with the vmware-rawdiskCreator command line tool and added to the .vmx file.

    My question is, since it is a server, I want it to load VMWare Fusion and start the virtual machine automatically at startup, but each time the virtual machine is started, a message appears stating "VMware Fusion requires administrator privileges to access Boot Camp disks.  Type your password for this purpose".

    Some research that it used to be far to say merge to "never ask" passwords, but this feature doesn't seem to be an option of Fusion Pro 8.

    Is there a work around to bypass the manual password entry requirement?

    OK, I found an answer to my own question...

    Although it doesn't seem to be an option to disable the prompt of the graphical interface of Fusion Pro 8, there IS one on the command line.

    First, find the UID of the user account that you launch VMware Fusion with the help of.

    ID

    (Often this will be 501 as the UID of the first user created on any mac).

    The official version said that WS allows only virtual up to 8 TB of disk.

    According to my own tests, it only limits the size of the VMDK for 'New - VM' Assistant.
    Once you have a greater vmdk - just tried a vmdk 10TB - WS won't complain about the size.
    I don't expect that WS will prevent the physical disks to use inside a virtual machine that is already configured.
    So in your case I think you started WS with a normal user account.
    Try to start as administrator WS - maybe even using the administrator account.
    I think that then it will work.
    Unfortunately, the error messages produced by vmware.exe are not really accurate-, so there is no way to know if you really have a bad super block.
    To test if this is really the problem and not just an error message - poor try to mount the drive directly.
    Please post the vmdk - want to know if there is something unusual about 5.5 TB in the disk.

  • Expand a virtual disk with new physical disks?

    Hello people,

    Pleas in law not to shoot me to ask what I fear it may have already answered somewhere and my research is poor and as still not turned up the answer.

    I'm relatively new to VMware, previous job was especially MS Hyper-V and is always to some extent.

    Hower to the point in question, I have a single host (VMware ESXi 5.0.0) with a single server VMware 2008R2 on her guest and the C: drive is quickly running out of space. The existing, aligned hard disk virtual hard disk has 10 GB free to extend the ramdisk with.

    Therefore, my thoughts are I might add an another one or two new physical disks and add them to the data store that is aligned with the virtual C:\drive to the comment server, I would then be able to extend the exisitng C:\ virtual hard disk with the new ability to drive two new physical drives added?

    Hope this sense makses, hoing it's okay and I get out of jail!

    Thank you very much

    Graeme

    Hello

    Please see this link because it deals with the procedure to enlarge a vmdk and extend partition in comments

    First enlarge the data store after the addition of physical drives. Select the data store, properties, increase and the LUN detected.
