• 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.

• VMWARE Newbie - installation problems with the guest operating system

  I heard a lot about the use of VMWARE for a long time so I downloaded and then installed ESXI 3.5 on a test area.  I installed the client and have been able to create a new virtual machine.  However, I run into some difficulty with installing a guest operating system.  All the pdf that I could find have suggested that simply by putting a CD in the server's drive and then turn on the virtual machine would start the my guest operating system installation process.  Unfortunately, my VM doesn't seem to see my CDRom and tent drive a start-up network, followed by a brief wait for the message 'Operating system not found' timeout.

  Can someone please help me find a way to create a new guest OS on my VM so that I can.

  1. understand the process

  2 start testing.

  Thank you in advance.

  If you have installed of course the VI Client to create the VM, and you insert the CD into the ESXi host? You can go to change settings on the virtual machine, click the CD/DVD and select the option use the host device. Also ensure the connection to turn on is checked.  When you turn on the virtual machine, it should see the CD that you inserted in your ESXi host. Once you get the operating system to load, you can configure to allow remote desktop connections and access the VM as a traditional physical machine, rather than relying on the console of the VI Client view.

• How to activate the RS232 and USB communication on the guest operating system in vmware ESXi 4.0

  I installed a software in the OS (redhat 5.0) invited to vmware, it must communicate with the device via RS232 or USB

  but not to communicate.

  Vmware tools is installed.

  I try to change the attribute of vmware, add the com port and USB, but still, it does not take effect

  What is the RS232 or USB available on the operating system called?

  How to activate RS232 and USB?

  USB and series are not available in a prompt. There are IP network series and usb IP devices that can be used.

• Interact with the guest operating system without providing a password of the host

  Whenever I try to use the copy-VMGuestFile or Invoke-VMScript I'm prompted for a name of username/password for the host, I am already connected to vCenter Server I should not need to provide a name of user and password for the host? As many users in vCenter Server accounts do not exist on the host and would need to be configured individually for each host?

  AFAIK not with the current construction of PowerCLI.

  But if I remember correctly it intends to simplify this in a future generation.

  Maybe can someone of VMW confirm?

• How to connect to _old_ Sync one and only device with the new operating system

  Howdy,

  I own a "device" (laptop) and have used Sync to store my bookmarks and passwords online as a way of not having to worry about backups for these courses of frequent relocations due to the OS-experiences etc.

  Yesterday, my HARD drive crashed hard, so I set up another and a new OS installed (Qubes R2).

  Now costs 32 FireFox that accompanies the installation won't let me not reconnect to my old data synchronization.

  No other devices available (or systems USB - life) with recently synchronized data locally.

  It seems to me strange _VERY_ that due to certain policies to force people to start using an account of FireFox, I must now be deprived of my current Favorites and passwords, even if I _DO_ toxic Apple bite and create an account.

  WTF is the logic here?

  See you soon,.
  Pudsy

  The 'logic' is that Sync has always intended to be used to synchronize several installations of Firefox, never to be used as a 'backup service' as you did. Plus the fact that the transition to the new version of sync with Firefox accounts, started 5 months ago (for users of the Release - version and about a year for pre-release nightly testers).

  You can try to install a version of Firefox 28 [or an earlier version] of Firefox and see if you can connect to synchronize to recover your data.

  I do you, you can upgrade to Firefox 32 and then update your sync account.
  Synchronize your bookmarks Firefox, history, passwords, etc.

• Blue screen on the guest operating system with code BUGCODE_USB_DRIVER when I connect an iPod

  Hello

  I use VMware server 2.0 (build 122589) on Windows VISTA 32 bit. The guest operating system is Windows XP SP3.

  When I connect an iPod Touch on the guest computer, after a few seconds, there is any time a blue screen Windows with code BUGCODE_USB_DRIVER. I have connected 2 different digital cameras and the crash does not add.

• 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.

• VMPlayer newbie - switch back and forth between the host and the guest operating system

  I am newbie to VMPlayer. I just installed VMPlayer 3.0.0 build-203739 on Red Hat Linux 5 (host). Then I created a VM comments Kubuntu (8.10). So far so good. In the VMPlayer window, I selected 'play Virtual Machine '. After this, the host operating system controls disappeared and I could see a taskbar on the top of my screen and I could also see Kubuntu startup (in an area of the small window in the center of the screen). The problem I'm running is that I'm not able to navigate outside of this area of the small window. I'm not even able to click/Select the taskbar of VMPlayer top of the screen. The mouse movement is limited to the area of the small window. How to and fro my host and the guest operating system? Is there a key combination? I finally had to stop my VM guest to return to the control of my host system. I guess it's a problem quite newbie that I am running. Any help would be greatly appreciated.

  Hello, welcome to the forum

  Host Windows to switch between comments and the OS (when you are in the guest operating system), you must use ctrl + alt.

  According to this link , it's the same thing in Linux host too.

  >Default VMware Player uses key combination Ctrl + Alt to jump out of the guest. Then CTRLAltdel is accessible via theAltInsert command. If you find this annoying, you can change the jump shortcut to CtrlAltshift by adding the following lines to your ~/.vmware/preferences:

  > pref.hotkey.shift = "true".

  > pref.hotkey.control = "true".

  > pref.hotkey.alt = "true".

  After your installation OS in the virtual machine, install "VMware Tools" on it so you will get better performance and some improvements (like moving your mouse out of guest to your host operating system operating system and Vice Versa, or be able to copy beyond host/guest, better resolution on reviews and...)

  I hope it helps a bit.

• 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.

• CPU has been disabled by the guest operating system error

  When I try to install some VMs based on Linux of ISOs, in a few seconds, I get the error:

  "The CPU has been disabled by the guest operating system. You must turn off or reset the virtual machine at this point. »

  (See also the screenshot attached)

  This happens on other ISOs based on Linux/Windows. I googled the web & VMTN, but have not found relevant

  The issue I'm having is on the slopes significantly slower than #2 #1 VM.  #2 works pretty decently.  #1... well over this long last week I started it after being unused for awhile.  I got the prompt to install VMTools so I did this. He took over 36 hours to install VMTools!  ;-((.  I want to update the operating system with updates from MS since several months, but I did not "months (or more!" to run through the update.

  What are the options (performance etc.) would you suggest for #1?  Apparently, the two #1 and #2 are the same, as far as I KNOW, in all other aspects of the guest operating system and settings.  Is there a setting/performance video or paper about this game and how build/debugging etc. for optimal performance?

  TIA!

  Hello.

  How did they build each of these virtual machines out there?

  #1 is slow if #2 is also well off?

  Good luck!

• CPU pegged at 100% in the guest operating system

  Hi all

  New to this forum, so I hope I'm posting in the right place. Note that I'm not our VMware admin, but rather, I have a server I have to admin that has been converted to VM via the P V. apparently process, our group has converted nearly 50 PMs successfully and of course one of mine is the only one who has a problem now. We have a custom application that has been developed to synchronize data between ESRI GIS and databases SAP. The code is about 7 years old and runs on a version of Oracle (9.2) and is Java based, both on the same vintage. It is not possible to upgrade by the creator going out of business and not having is not the source code. I ask this to understand that the problem is probably with the programming, but thought it was worth it.

  Anyway, one of our guard batch process fail with a Java out of memory error on the virtual machine. It works well on the PM. A consultant ran the diagnosis with a Profiler memory on the virtual machine and concluded that the program never went beyond 256 MB and we have 1 GB allocated to the guest. We now consider the CPU issues. The only other thing we know is different is a matter of hyperthreading (HT). The PM is certainly HT'd (1 physical CPU showing that 2) and it does not appear that this setting met on the virtual machine. When you run the package on the PM, we see 2 CPUs in the Task Manager, and neither hits 100% for more than a few seconds for the whole process. On the virtual machine, we see a flatlined CPU and it is 100% most of the time until it fails about 15 min in.

  The sysinfo on the virtual machine shows a 2400 MHz CPU, while the PM shows (2) 3400 MHz CPU (due to HT). I checked all my other virtual machines, and they are all 'show' 2400 MHz, so this must be a virtual standard machine type? I think that the virtual computer guest has access to the CPU ramp according to the needs, but then I'm not clear why the task manager would show that he attached the entire lot? It is likely that task manager prompt indicates whether flatlined to 100% of a 2400 Mhz CPU, even if she isn't really the most? If this is really the most, our admin should not be able to increase the dedicated CPU (I looked at the console with him and did not see an obvious option for this)? Is it possible to enable hyperthreading on the * comments * OS to mimic what has had on the PM? We cannot add another CPU to the guest due to licensing issues. Oh yes, the guest operating system is windows server 2003 and VMware ESXI 4.1 server. Thank you very much!

  G

  The speed of the CPU that you see is the speed of the physical processor in ESXi hosts. You cannot increase this speed, however - licensing - usually, you can assign two vCPUs, virtual machine as a dual CPU core instead of 2 processors. This option has been added to ESXi 4.1. See http://kb.vmware.com/kb/1010184 for more details.

  What you need to do is to set the number of processors to 2 and add the advanced parameter cpuid.coresPerSocket = 2.

• How should be written the script for the use of the maximum memory of the guest operating system ever?

  How should be written the script for the use of the maximum memory of the guest operating system ever?

  Please teach the name of the object and the type and order, etc.

  You should be able to do it with the cmdlet Get-Stat .

  Something like that

  Get-Stat -Entity (Get-VM $vmName) -Stat mem.usage.maximum -Start (Get-Date).AddDays(-7) | Measure-Object -Property value -Maximum | Select Maximum
  

  This will return the maximum percentage in the last 7 days for the guests, whose name is stored in the variable $vmName.
