Performance of guest operating system

• 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.

  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!

• 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.

• The VM startup slow down, delay long before the guest operating system begins startup

  Evaluation of VMWare to set up the VM for the maintenance of the software. Set up a virtual machine, install Windows 7 SP1 32-bit, everything works well. Once started, the performance is excellent.

  The symptom is that when you start the virtual machine, either starting from cold boot or suspend, there is a significant delay before the power of VMware on / start screen is displayed. Once it appears, the operating system starts starting (or the recovery of wakefulness) quickly and performance is normal after that. During the start-up period, the whole system is insensitive, host and guest operating system.

  See the extract of newspaper below to 09:54:28.619 moment where the delay occurs followed by the entry concerning 09:55:11.625 time when start continues, a delay of 43 seconds during which nothing seems to happen and the system does not respond. After that, everything is fast.

  Any ideas or suggestions?

  Hello

  I know what you want to say as I've seen sometimes as well. But especially on older hardware or if there are problems with regard to particular resources. For example I saw this on an ESX host (yes I know product different) where there was a problem with the storage not enough providing IOPS / s.

  I saw also this on older versions of Linux (IIRC 7) workstation where the host had an Atom based CPU, there I updated to more RAM and a more recent version of the workstation and the problem disappeared.

  Then I also saw it on the 4/5 merger when my host operating system was out of memory and I tried to start another operating system to prompt anyway.

  I do not consider a normal behavior for the slow start and does not respond, it is an indication that the hypervisor is seeking some resources, but does not receive them fast enough.

  The reasons can be many. Indeed things like antivirus could be biting you if she tries to analyze all files (including virtual disks) at their opening.

  FWIW, I also understand the support response as would be expected if your host is a bit thin on the resources (for example, trying to start a VM 1 GB on a host Win7 with only 3.5 GB of RAM) and if the virtual machine runs OK after the initial startup delay, it's mostly just an annoyance.

• 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.

• 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.

• Guest operating system fails in VirtualBox

  Hello

  I installed Windows 8 teacher and it's a real pack. From now on, I have no probs for use with all other packages.
  But recently I wanted to install Oracle Virtual Box and install an OS linux as a guest operating system.
  In the VirtualBox, I could install Windows XP without no prb. But when I try to install CentoS 6.3. Right after installing all the packages and when restarted, I got the following error message.
  Oracle VM VirtualBox Manager has stopped working.

• 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:

• 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,.
