• How to activate HV in guest operating system

  I use VMworkstation 6.5 on windows vista ultimate 64. I installed Windows 7 RC1 64 bit on a virtual machine. Virtualized in Windows 7 windows xp mode requires hardware virtualiztion to run. I HV activate in my host bios and Windows 7 in my VM correctly identifies my CPU but there is no setting in the bios of comments to turn the HV. I read tne VMX settings file to the sanbarrow but have not seen all the settings to activate the HV within a guest operating system. Can anyone help? The feature of Windows 7 that I was more interested in checking out is how they well intigrated XP virtualization and legacy 16-bit app support for their new OS.

  No case - you can not move the CPU features required to a VM guest.

• VMDK size differs from that indicated by the guest operating system

  Hi, my said guest operating system disk hard is full to 30 GB, but the parameters of the virtual machine, it is said the vmdk is currently only 2.4 GB.  Anyone know what could be going on here?

  Configure you the VM to expand on the use and create NOT entirely the disk, it saves space.

  The VM disk is being created in 2 GB increments up to full capacity. And the OS disk is not full, it's (potential) CAPACITY of the disc, the drive was full the VMDK more would certainly be 31.5 GB as well.

• no storage device found more by guest operating system installation on a virtual machine

  Hello

  I'm trying to install a guest on a new virtual machine operating system, but I can't go forward.

  I use a Dell PowerEdge 2850 , the hypervisor Server VMware ESXi 3.5 update 3 and the VMware Infrastructure Client on my computer with operating system Windows XP host.

  I am able to create a new virtual machine, but also to start on a cd for installing a guest operating system, which is (still) of Windows XP. During the installation-Setup asks me to press on enter for a new installation, the next thing is a screen with the message that Setup cannot find any storage device! It's weird, because I use the same as other data store created vm is imposed and other virtual machines always work. I created the new virtual machine several times and deleted, this is no problem. I restarted the server, but that did not help.

  Any ideas? Thanks in advance.

  I also met this problem with a fresh install of XP VM.  Windows XP does not have a driver for the BusLogic or free storage controller... without that driver, only the virtual controller is not

  recognized and drives are not found.

• 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 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.

• 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.

• What iso (HR) Centos to use when installing on VM guest operating system?

  When you install a guest operating system Centos 5.5 on a VSphere VM, I'm a bit puzzled by this what iso i386 to download & install.

  • DVD: seems to be the right choice for me, although large

  • CD 1 of 7: will probably ask me to mount other CD.

  • the netinstall CD: should work if the virtual machine has network connectivity good to contribute to the installation

  Thanks in advance for all advice here... Lyle

  I always use DVD iso file (download via bittorrent client). Not only that you get everything you need in a single iso file, but it is easier to manage on the data store (where you keep the iso files OS). Locate a mirror which seems to be more close to where you are (in the world/country) and allows to start with. Of course, your connection speed will dictate how long it takes to download the file. I also usually download files iso of OS at home, so that I don't have to worry about sucking to the top of the bandwidth in the office, and I have no need to worry about a firewall rule prevents me to get the files.

  Once the installer has spent three or four cd iso files, I opted to enter the DVD ISO... It's simply more light and to download the iso DVD because it does not worry about change iso files during installation, or have several virtual cd/dvd drives connected to a single virtual machine. It is also faster set-up, because that's what reading the single iso file, not seven.

• Trouble installing the guest operating system

  All,

  Having trouble installing the guest operating system - Windows XP SP3. I followed the directions of the booklet that I try to boot from a local image and a CD. I can't able to get into the setup of the BIOS to start the virtual machine when you press F8. I am currently on a decentralized network that starts his BONES from a PXE server. When I turn on my VM, its shows the boot process than my actual desktop. I tried many configurations, but still problems. All instight would be useful. Thank you.

  Welcome to the forums!

  To enter the VMWare guest BIOS press F2, no F8.

  You can also add 'bios. BootDelay = 10000 "in the prompt .vmx file. This gives you more time to press F2.

  The virtual guest has a CD-ROM attached to it?

  Is it "connect to turn on?

  Is it connected to the physical machine (where the OS CD is inserted)?

• 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.
