• problems to receive a guest operating system

  Hello

  I have to be able to do a query on Windows 2003 virtual machines that use the BusLogic SCSI card.  However, I am having a problem just get the operating system of each guest.  Many guests (seems to be about 800 out of our 1200 guests) return a null value (I'd say less than 10 of them are turned off).  I tried with both the 1.0 version of the VI and also just upgraded to 1.5 to check that it has not been fixed.  Here again, I'm not 100% sure it's a problem with the Toolbox.  Anyway, that's what I've tried so far.

  First of all, I found a good virtual machine (vm1) and a bad VM (vm2).  I created two variables:

  $vm1 = Get-VM vm1name
  $vm2 = Get-VM vm2name
  

  Then I tried simply to list the property Guest.OSFullName of each virtual machine:

  $vm1.Guest.OSFullName <-- returned Microsoft Windows Server 2003, Standard Edition (32-bit)
  $vm2.Guest.OSFullName <-- returned nothing
  

  Other "guest" properties seem well as evidenced by the following output:

  "$vm2.Guest" returns:
  
  State          IPAddress            OSFullName
  -----          ---------            ----------
  Running        {1.2.3.4}
  

  The only other thing that I noticed (and I'm going to file a SR for the same problem when I am back in the office on Wednesday) is that if you view all virtual machines in the VI Client and guest OS type, there are a lot of things that just say 'unknown '.  I've noticed this on 2.0/3.0 and now I'm under U3 2.5 and 3.5 U3 everywhere.  If you simply to change the settings of the virtual machine and click OK (without making any changes to anything) it will fix the guest operating system 'unknown '.  If you click on the 'Options' of the section of edit VM settings tab, it shows the correct guest OS it.  However, after click on this tab by clicking OK causes an error message something to not be able to change this setting in the current state (power on).  Nevertheless, at the beginning I thought all the unknowns explained my missing Microsoft VMs, but there are more than 100 virtual machines or so that are listed as unknown, so I am always short way.

  Finally, I searched this topic on the forums and learned about the Get-VMGuest cmdlet, which I managed for ever noticed before.  So, I tried the following:

  $vm2 | Get-VMGuest
  

  And got the same results as above (shows its power status and the IP address, but any type of OS).  VM1 works very well with the above code.

  Does anyone have ideas on this?  I even buried down and use Get-View and pulls the. Property Guest.GuestFullName out and it is also empty.

  Hi Allen,.

  I've never known tools that are so far out of date that you do not get a guest operating system, but I wouldn't be surprised it. You should always be able to get out the Tools version number in any case (even if not Get-VMGuest in this version).

  There is a significant difference between these people that the prompt that signals the VMware Tools is the real guest OS. The comments you get Get - VM or Config.GuestFullName is the value that is set when creating the virtual machine. This value cannot be identical to the real host. For example, I could create a virtual machine, select Windows 2003, and then install Redhat on it. In this case, Get - VM would net the VM as a machine virtual Windows while the tools would (correctly) reported as Redhat.

  In general, use tools when you can. If you don't get given tools, it can be wrong.

• Performance problem with the guest operating system

  Hello gurus - I have one of the most unusual questions, I ran into a few time.   Here it is:

  I have a guest w2008R2 OS - installed in a 5.1 version of VM 7 vSpherer - which has an Emulex LPe 12002-E 8 GB dual HBA port is assigned to the as 2 PCI (1 device per port) via DirectPath devices

  The guest operating system has an application that performs backup tests.   WWPN of the HBA is zoned in the fabric and declared in the interface of Compellent Storage Center and everything is good here. the application creates a replay of a volume, mount it as a drive, read all the blocks, then dismantles and moves then repeat the process with what ever additional volumes should be safeguarded.   It is so cool I have do this with a VM right and not a physical host?  (would be cool if I had work NPIV but that's another story, not with technology HBA vendor support...)

  So, what's the problem?   Well, the bed the mounted disk backup will work extremely slow as slow as 5MB\sec flow, then during any other activity takes place on the system the flow jumps up to 150MB\sec all of a sudden and will continue to run fast for a long time and finish jobs on time with each work taking a little more than an hour.  But when the slow going the same work (all jobs are the same, they are simply by reading all the blocks of a bunch of 200 GB volumes and wrote a set of NULL value, do not forget this is just test) takes up to 10 hours to complete.

  I think that what is the culprit?   POWER MANAGEMENT.

  I have just about each performance counter and the journal of events known to man and I don't see anything abnormal on the table, ESXi virtual machine, nothing.  But what I see in the newspapers is any kind of activity that could happen in a transparent manner to save energy.

  FACTS on this case:

  -Reservation of memory is defined (it must be for directpath otherwise, you can't power on the virtual machine)

  -Booking CPU - has not been defined before an hour ago, I gave her just a small reserve for this rule, so I do not know if this will help alleviate the slow flow, or have an effect on what I think is a question of power (unit linked) management

  -windows power management is set to high performance never-ever - but not until an hour there doesn't I changed advanced settings for USB Disabled------turned off.  PCI peripheral energy saving setting was already off.  Which is in contradiction with my theory.  But maybe, just maybe, something is broken somewhere, or could be a bug... blah blah blah

  -the HBA, Emulex, as it appears in Device Manager in the guest OS doesn't have a power management tab to disable the feature, I don't see that the adapter VMXNET3 had this tab, and I turn off the power save setting to be conservative, do not think that it was the culprit, but as there is no real data running through the NIC.  The data is simply to be read from the disk mounted, not copied on any wire Ethernet.  never the less, in the Emulex properties is a Details tab and a selection of power data, and performance data indicate you what power mode, the device is, as well as feeding supported systems.  D0: full power, but D3, which shows as supported by the device, is an energy saving mode.   I could not yet attend the setting at the time of slow activity, my good intention as soon as possible. He is currently shooting in D0, full power.

  This is so what I have to offer on this, I hope that its just...   If I'm missing something, or if others have experienced this massive loss of unknown flow without reason and have resolutions, please share.

  If there is a way for me to disable power on the Emulex HBA management inform you please, I don't mind if I stop to enter the firmware, if that was even possible.  But if possible I would disable it immediately before any new tests are executed.

  The root cause of this issue has never been identified by VMware support which for me is a question of ugly.  Reservation of CPU for the VM using directpath IO with HBA installed in it corrected the problem.  I'd be leary with direct path IO.

• Is it possible to install multiple copies of Windows 7 in Virtualbox as guest operating system

  Hello

  My laptop runs on Linux OS, I installed VirtualBox. Now, I would like to install multiple copies of Windows 7 on VirtualBox as a guest operating system.

  Is this possible?

  My activation will expire after 3 installations?

  What are the limits in this situation?

  Microsoft treats several facilities in VirtualBox (as guest operating system) as a single installation instance? I think that the hardware (motherboard) is used as a fingerprint to detect changes in the systems, but as the material is going to be the same custom installation will be treated as a single instance?

  Help, please...

  Thank you

  Hello

  There are not 3 installs with 1 license

  A Windows license is for a single installation, and this includes in Virtual Machines.

  See you soon.

• Avoid checking "the guest operating system has locked the door of CD-ROM. disconnect anyway and replace the lock?

  Using PowerCLI, I'm trying to create a script that logs off the CD player and affects the client machine and Passthrough IDE using the command:

  Get-cddrive - VM SRVVM616 - netscan02.kb.se | game-cddrive - nomedia - confirm: $false

  * (where SRVVM616 - netscan02.kb.se is the VM name in this case)

  But I can't get rid of an audit question that arises in vSphere Client:

  'The guest operating system has locked the door of CD-ROM...

  Unplug anyway and replace the lock? »

  The script hangs until I answered the question, and who does the idea of a useless script?

  How can I avoid this issue?

  Maybe the method I described in answer to the question! could help.

• Cannot run the program in the guest operating system

  Hello

  I'm trying to run a program file (an .exe) in a virtual machine via vCO using executeCommandInGuest.

  The thing is that the .exe file starts a user interface to display the status (do not ask for entry) when it runs locally. When I call the script of vCO, I get the following error:

  Error while executing command (can not run the command: InternalError: a general error occurred: a program could not run on the guest operating system (name of the dynamic Script Module: executeCommandInGuest #40) (name of the dynamic Script Module: executeCommandInGuest #46))

  
  

  If I try to call a .bat file in the VM that starts the program of the WF works but the .exe file is never started in the virtual machine.

  If I specify to run another .exe for example ping.exe only complete control of WF and if I specify a .bat file that call ping.exe he also successfully complete.

  There is no silent mode for the .exe I need performed.
  

  Any help would be appreciated.
  

  Thank you

  Magnus

  The problem was caused by the user access control. Put forever does not resolve the problem, disable it through the user interface, restart the virtual machine, and then continue with my script.

• Surface Pro 3 - errors when you try to start a guest operating system 64-bit

  I get the following errors setting up an Ubuntu guest operating system.

  This virtual machine is configured for 64-bit operating systems. However, the 64-bit mode is not possible.

  This host supports Intel VT - x, but Intel VT - x is disabled.

  Intel VT - x can be disabled if it has been disabled in the BIOS/firmware settings or host was not powered by bicycle since changing this setting.

  (1) check that the settings BIOS/firmware activate Intel VT - x and disable "trust execution."

  2 turn on the host if either of these BIOS/firmware settings have been changed.

  (3) turn on the host if you have not done since the installation of VMware Workstation.

  (4) update of the BIOS/firmware from the host to the latest version.

  I've been Googling this problem since yesterday and so far, I have not come to any possible solution. Certainly, I can install the 32-bit linux flavor, but that doesn't help me when I run the installation to other 64-bit operating systems.

  I was able to resolve the issue, after most googleing. I'm always a little surprised that it works, but hey, Ubuntu is installing.

  I installed Microsoft Visual Studio, including phone windows SDK (must be included).  I disabled and then Hyper-V by issued this command in a shell of administrator command:

  bcdedit/set hypervisorlaunchtype

  If you want to reactivate it, you then type this command

  bcdedit/set auto hypervisorlaunchtype

  Once I rebooted and restarted Vmware, I could start Ubuntu and start the installation process.

• T of what guest operating systems will start the VMware Support for EFI?

  Is there a list of support guest OS for the EFI firmware?  Mianly supported by VMware - do not try, fail, call support technique etc etc.   My experiences on the TP forums, I guess that there is not.  Some OS (such as Windows Server) come with a screen to choose BIOS/EFI firmware.  If not, you need to go to setting > Hard Drive OPtions-> advanced _ > boot using EFI.  In particular there at - it versions of Linux that you give you option of BIOS/EFI firmware before the confutation of VM is complete, so the hard drive then be custom.

  We will officially support the EFI firmware for any guest operating system to which all the following conditions are met:

  • We list this guest operating system, supported in the VMware Compatibility Guide for operating systems and your virtualization product.
  • The guest operating system supports EFI in the operating system installation media.
  • Support the guest OS EFI has no catastrophic flaws (for example Fedora 12 x 64, FreeBSD 11, Centos 6.0 through all the 6.2 have catastrophic flaws).

  New computer virtual assistant of 11 workstation has only the option of EFI firmware for Windows clients.  Special mention, do not yet support us Easy Install for non EFI customers in 11 workstations.  For all other customer support EFI OSes, you can do a manual installation after choosing the EFI firmware in the virtual machine settings > Options > Advanced > Boot with EFI instead of the BIOS.

  I don't understand your concern about the personalization of the hard drive... Could you elaborate?

  See you soon,.

• Guest operating system installation

  I have Vmware workstation 7 and try to install the guest operating system, but it gives me the error message like, no operating system. Can someone help me please?

  In the .log files, I noticed that the name of the file you linked at the end of CD/DVD in the DAA and DAA (Direct Access Archive) files are not ISO Image files, and are not directly usable with VMware Workstation!  You must use a valid Image ISO Bootable file!

• Help. The CPU has been disabled by the guest operating system. Power off or reset the virtual machine. WHY?

  Greetings.

Power off or reset the virtual machine. I Don t know why my server displays the error if my environment was OK. Could be a kernel problem? operating system problem?

  Ideas?

  Thanks for the help.

  Did you recently patch your VM? Looks like when the guest operating system runs the incorrect commands that it can have a deactivated processor.

• VM does not start after the crash of the guest operating system

  VM Workstation 10.03

  Host OS Ubuntu 12.04

  Guest OS Windows XP SP3

  VM normally works well under VM for over a year.

  While I was updating a mp3 Player XP is crushed, and even power off the virtual machine does not work.

  After a Resart of the host operating system, the guest could not start.

  I deleted the directory .lck file.

  When I start the VM OS prompt written

  Loading... - VMware Workstatiion

  and nothing else happens.

  Another guest operating system will work very well.

  How can I restart my XP?

  After a day down from the host (a very cold reboot) and deleting all .lck files.

  VM aloowed me to dispose of the session.

  After that cold booted XP as it was before.

  Thanks to a.p. to put me on the right forum.

• Guest operating system compatibility

  Dear team,

  We have mix U1 ESX5.1 and ESXi5.5U2 environment. We are palnning to deploy Windows 2012 R2 on U1 ESXi5.1 host, I want just to cofirm will, I was able to migrate 2012 SMV of ESXi5.1U1 to ESXi5.5U2 I found that there are a few incompatibity with mixed version as shown below KB. I would also like to confirm that they said that this applies to 5.0.x and 5.1.x.

  

  need your urgent help on the same.

  concerning

  Mr. VMwrae

  Ko 2033723, the affected guest operating system is Windows Server 2012 (not R2) and hosts ESXi 5.0 Update 1 or ESXi 5.0 P03... then I think you should just avoid using this version of the build host, given that the VMware compatibility shows that Windows Server R2 2012 is compatible only with ESXi 5.0 Update 2 and later versions.

  On the other KBs, make sure to read workaround, and everything will be OK.
