Relationship between memory of comments and the host memory usage

Hello

I noticed today that the memory usage of my cluster rose close to 90% in all of the blades. I checked and found that a number of virtual machines is everyone using over 3 GB of memory host. When I went in the performance monitor for each of these virtual machines, they used only a maximum of 400 MB.

How the memory usage of comments relate to the host memory usage, and how I can reduce the amount of memory used host so I do not have a performance hit through the cluster?

Running ESX 3.0.2, VC 2.0.2 Dell Poweredge servers with 2 processors 1.86 GHz quad core and 24 GB of RAM.

See you soon

Graeme

  • Virtual LAN with guests and the host only

    Hello

    I have a win server 2008 r2 host and a couple of virtual machines.

    I want to create a VLAN that contains the host and guest of the virtual machine. I intend to host the domain controller.

    I put the network connection from the guest to "host-only '.

    Then I tried ping between the guest and the host. Ping fails. "request time out" @host and "destination host unreachable'@guest.

    Firewall is turned off on both.

    What could be the problem? Is there another way to reach my goal?

    Kind regards

    Dembele.

    Did you stop the firewall service, or you have turned off the firewall? Stopping the service does not work.

    In any case, take a look at for example example 4 in the http://support.microsoft.com/kb/947709/en-us for how to configure ICMP (ping) settings.

  • Dedicated network adapter to the virtual machine and the host computer not let can visit his profile

    OK, here's my question, I know how to give themselves a phyiscal nic to a vmware, but I wanted to take it one step further and do not leave the host send or receive data from this network card, only the virtual machine can use this network/NIC...

    Here's my reasoning, I have to network conections, one is for my internal/field network and the second is a direct connection to the internet (Comcast) I don't want to use to separate the machines have for internet connection, I want to be on the same machine phyiscal and have just the vmware machine talking to comcast... is it possible?  I am running VMware workstation 7, last update.

    Thank you

    I assume you are using a Windows host?

    If Yes...

    -first set up networking networking with vmnetcfg.exe

    -assign vmnet0 to the network card for the internal network

    -assign vmnet2 to the network card used for direct access to the internet

    -Right-click on the map network-icon in the systray and access the properties of the network adapter for vmnet2

    -Disable all other protocols and the Protocol of vmware_bridge for this network adapter

    result: a virtual machine that uses vmnet2 can directly access the internet and the host has no IP address for this network adapter - and therefore cannot use it.

  • How to re-scan the relationship between computer ip addresses and network names

    On my SBS 2003 network with six or so field PC clients and a few extra non-domaine workgroup (a few XP, some Windows 7) PCs, computers can access each other using \\computername. When I change the IP normally assigned by dhcp to a computer on my network to a static IP address, sometimes the other computers can no longer use \\computername, but I now have to use \\ip-adress instead.

    For example, A computer can open the folder "\\mypc\shared". I change the IP address on "MyPC" to a static IP, 192.168.0.220. Now the other computer must use \\192.168.0.220\shared"to access this folder '; \\mypc\shared' returns an error that the specified computer could not be found (or something like that).

    I know that I can enter the names and the ip addresses in the Hosts file, but it is manual, and computers it does automatically the first time.

    How can I get the PC to re-scan the computer names and IP addresses and link them back to the top?

    This can be a master browser problem, look in the event viewer for clues, these browser issues usually register error event ID 8021 and 8032.

    Note that this can take up to 13 minutes for a master browser broadcast and announcement answers from computers on the network, the browse list may not be filled until the ads are complete, so everything can be good.

    Stop and restart the browser to the computer repaired (or restart) on the computer that has the functions of the master browser will force a regeneration of the browse list.

  • Remote Desktop - conflict between the remote control and the host user?

    We set up Microsoft Remote Desktop on a Mac with a remote computer that is running Windows 7 Professional.

  • Another discussion to see a comments from the host Web server

    Howdy,

    I ran into something really puzzled. I have windows 7 host machine and two VM. Ubuntu 11.04 is one the other is RHEL7. The fundamental problem is that, since my host machine, I see an Ubuntu apache server and I do not see the server apache RHEL5.8.

    Details. I'm running 8.04 vmware and have reinstalled vmware-tools on every machine after the upgrade. I'm running an internal NAT. The host IP is 192.168.2.1. The Ubuntu IP is 192.168.2.128. RHEL 192.168.2.129. The problem is between the host and the 192.168.2.129 box of RHEL. What's weird, is that I do not see my server apache RHEL host, but of the terminals on both boxes, I can ping another machine by IP address and since I edit/etc/hosts(buried in c:\windows\system32\drivers) I can ping between host and guest by the url "myapp.local" as well. The period of INVESTIGATION were determined by ipconfig and ifconfig on the host and the guest respectively. I watched netstat on the client and do not seem to have anything httpd listens on port 80 on the guest. I'm really at a loss. The Ubuntu box configured the same way works, but the RHEL box fails.

    I don't know if I listed everything that could be of use here, but if someone could chime in with ideas I would appreciate it. In brief

    (1) ifconfig shows URL

    (2) pings may be

    (3) dns is defined in/etc/hosts

    (4) proxy ignore is set in firefox on the host and the proxy reviews configuration to avoid transmission by proxy problems

    (5) web page expires, the server is invisible

    (6) newspapers on the comment server don't watch not demand of the host being considered.

    Thank you

    Danny

    Based on what you said in the OP I would say that you need to properly configure your firewall on the client to allow WWW (HTTP).  If not that something is still not set up correctly and very probably not really a question of VMware.

  • Problem with Virtual PC: can automatically log on to the comments because the host name is added comments user name after you have entered identifying information.

    When activate the integration in Virtual PC features, then the dialog box "Enter your credentials" appears. After entering the username and password of the system cannot connect because the host name is added in front of the user name that I entered. Example: Guest user name is "Admin". The host name is "XYZ". Vrtual PC try to connect as a user "XYZ/Admin" on the comment system. After getting the error message I can manually correct the user name in the normal windows login screen on the client and open a session. However, no saved credentials, to be asked to log on again whenever I have resize the Virtual PC window. Any ideas how to solve this problem? Thank you!

    Hello

    What is the error message?

    Please try following the steps for the computer to remember the credentials and do not ask the password to open each programs:

    1. when it asks for a password, click Cancel . Without integration feature, you are allowed to log on with an account that do not have a password.
    2. set a password for your current user.
    3. click on Tools , Windows Virtual PC, choose the integration features allow.
    a. type the password, check the box ' remember my references of "and click OK to open a session.»
    b. after joining the domain, logon in XP mode with the local administrator account.

  • vMotion works between HP DL380 G7 and the Gen9

    Hi all

    VMotion I would like to know how working with HP DL380 G7 HP DL380 Gen9?

    Can someone help me?

    vMotion between this two servers:

    HP DL380 G7:

    Intel Xeon E5649

    Embedded NIC 4x1GbE

    + NC364T PCI Express Gigabit QuadPort

    HP DL380 Gen9:

    Intel Xeon E5-2650v3

    Embedded NIC 4x1GbE

    + 10 GB 2-port 10GBASE-T 533FLR-t HP FlexFabric

    Can someone help me?

    I would be very grateful

    Ralf

    The G7 has a CPU of generation Westmere, the Gen9 has a generation of Haswell CPU.

    vMotion requires that you have the same subset of games of CPU instructions and common on the source and destination of the CPU and active features in the server BIOS.

    This means that in your case:

    You will be able to vMotion virtual machine that has been powered on the host of the G7 (VM runs with Westmere instructions) for the Gen9 and so (but only if you don't re - power cycled the VM on the host G9).

    But you will not be able to vMotion virtual machine that has been powered - we on the Gen9 host (VM runs with Haswell instructions) to the host of the G7 most old car is missing these more recent CPU instruction sets.

    VCA comes here. By activating EVC on the common cluster with the generation of CPU down (in your case Westmere), all guests will present only these instruction sets to virtual machines when they are powered - on, which makes possible dynamic migration through the different physical CPU generations.

    See the following articles for more information about CVS:

    VMware KB: Enhanced vMotion compatibility (EVC) support processor

    VMware KB: EVC and CPU compatibility FAQ

    Alternatively you could manually hide CPU instructions by VM - with advanced options if you don't have a source host and destination in the same cluster, but it is a tedious task and I would not recommend it.

  • Update comments before the host tools

    Hello

    Our backup software (TSM for EV) checks if the VMWare Guest tools are 'in progress', before you perform the backup of the application.

    This means that when we improve a host for the new version, the backup of the application of all the virtual machines on the host will fail, until the tools are upgraded.


    However, the cheque will go through if the comment tools version is newer than the version of the host.

    Then...

    Is it possible to orchestrate the tools update to a newer version than the tools on the host?

    (In addition to using a single host 'host jump' update for updates, and migration of virtual machines on that host one).

    Best regards

    Martin



    Is it possible to orchestrate the tools update to a newer version than the tools on the host?

    Yes, it's possible and fully supported to run versions of VMware Tools in the guests who are more recent than the ESXi host versions. For example, you can use the latest tools of U1 6.0 even on the hosts 5.x. see: product VMware interoperability matrices

    To obtain and deploy the latest tools, you have a couple of different options available; you don't need to bother with a "host of jump' or whatever it is.

    1. just update the package tools-light of your guests, for example with MUV. This beautiful thing is this can be done online and requires no maintenance mode or a reboot of the host. Make sure that no virtual machine currently has VMware Tools mounted ISOs.

    2 extract the ISOs tools the bundle version (patch) of target offline or installing ESXi ISO.

    3 download https://packages.vmware.com/tools/esx/index.htmlTools packages. These correspond exactly to those of the packages included in the packages offline (patch) or installation ISOs. (Just get the .exe files big, no need to enter an ISO.)

    4 download the new standalone version 10.x of the tools of:

    https://my.VMware.com/group/VMware/details?downloadGroup=VMTOOLS1005&ProductID=491

    http://pubs.VMware.com/Release_Notes/en/VMwareTools/1005/VMware-tools-1005-release-notes.html

    Personally, I prefer not to bother with the ISOs editing or updating through the vSphere Client interfaces, but using an automated custom installation with the package of relevant tools like this:

    C:\VMware-tools-9.4.12-2627939-x86_64.exe/v number! REINSTALLMODE = vomus ADDLOCAL = DELETE all the Audio, BootCamp, FileIntrospection, Hgfs, NetworkIntrospection, Unity REBOOT = ReallySuppress

    This also some unnecessary components like unity, which are available on the position of work/Fusion/player, and eliminates a forced reboot.

  • Exadata - any changes in functionality between V2 / X 3 and the ESS/RDBMS?

    All,

    We are running a quarter V2-rack on 11.2.0.2 BP7 and 11.2.2.3.2 ESS. We're heading to a quarter-rack 3 X little which runs to regardless of recent older versions and the RDBMS/GI/ESS.

    We use on our current Production environment, of hepatocellular carcinoma and discovered that with bitmap indexes (which we have a lot), it was necessary to disable the index, perform the HCC compression on the table and then rebuild the index later.


    Obviously, an operation very intense when we have HUGE clues.


    Anyone know if this same behavior in 11.2.0.3 ESS RDBMS/more later? We are always forced to disable the index before run us HCC on the table or have the relationship between the index bitmap and HCC cooled a bit?

  • How to create a relationship between a Bock DB and not block DB

    Hi all

    I work with form of oracle 10g.

    I created a custom form. I have two blocks. One is a DB block and another block of control (that is to say multi record blk).

    I tried to create a relationship master detail between these two blocks.

    The Master block: LC_Master_BLK (DB Block).

    Detail block: LC_Detail_blk (no DB Block).

    Form object browser I click on the link in the block of master and a pop-up window opens and form there I select details of the block.

    And I give the join as condition

    LC_Master_BLK. PO_HEADER_ID = LC_Detail_blk. PO_HEADER_ID.

    I did po_header_id as primary key in my custom table, refred in my main block.

    But it shows the error
    FRM-15004: error while parsing the condtion of join.

    Can someone tell me how to solve this problem.

    Thanks and greetings
    Srikkanth

    Name of query data Source The block property is required to establish a relationship between the two blocs.
    Without that you cannot set up a relationship between the two blocs.

    In any case

    If you get has managed to implement a relationship b/w blocks providing the Query data Source name property value.
    You can't enjoy with this relationship
    because
    No detail block must store data (as it is a block Non-DB)
    Nor will it extract data from DB.

    Hope you understand this now.

  • RDP of comments to the host operating system

    Using VMware server 1 on a box of Windows XP 32 bit, I have a ubuntu vitual current execution machine. I have ssh open via the vitural ubuntu machine since I know how to secure * nix a lot more than I do windows. But sometimes I have to use a program on my XP machine remotely, in which case I need to remote desktop of Ubuntu to Windows hosted OS virtual machine. Whenever I do that, the RDP Protocol to connect, but then freezes, closes and I get the error 'connection reset by peer '.

    I googled for answers to this problem, but have only found people trying to rdp between the host and the guest. This isn't what I do.

    Are there any changes I have to do to make this work?

    It's a normal bridged interface. Thank you.

    You connect virtual machine Ubuntu to XP box... the XP box that hosts the same virtual machine Ubuntu?  So then realize that RDP to XP does NOT allow for the interaction of the console.  If the RDP session has control.  But the RDP session is displayed on the virtual machine, which is displayed on the host XP computer.  If you can not RDP to host any virtual machine running on XP host.  (Try RDPing from another physical machine to your XP box and see what is happening on the screen of your XP box.)   Windows Server operating system can be configured to be the Terminal Server farm, which would allow you to RDP to host because you do not take the console.  But not on XP (Vista or Win7.)

    So, you'll have to RDP to another physical or virtual computer that is NOT hosted on the area of XP you are trying to connect to.
