Do not allow the virtual machine to power on if the host memory usage over 75%?

• Questions on the host memory usage

  I was wondering if someone could give some insight on the following situation. We vSphere host set upwards with 32 GB of RAM. On this, we have 10 VMware View desktops and a couple Server VMs. We have configured each in order to have 2 GB of RAM. The host is showing an alarm for the host memory usage, but if you look at each of the virtual machines Windows XP, memory is granted way superior to the active memory. We have no reserve set and actions are set to normal. I wonder why the system reports a memory constraint when the largest part of the memory is alocating is not active.  In addition, the shared memory is showing 0. So this means that the memory page sharing does not locate? Am I missing something?

  ESX has called fresh General.  A virtual machine has 2 ways to manage memory.  a physical machine has one, physical RAM, and when this physical RAM disappeared, the operating system is left with only one option, Exchange.

  VM works the same way.  A material divides the virtual machine into small sections, only they have hard limits.  So your VM is 2G, the operating system and virtual machine sees only 2 GB of RAM.  When this RAM was gone, the operating system must decide where the extra RAM is come.  Since it is a Vritual machine, the RAM of the machine can ALSO be swapped.

  So, when you create a virtual machine, and you do not have reservations, you say that the Virtual Machine to get the RAM of the host, if this fails, get from a pagefile on the RAM disk.  If not THEN the operating system can use internal swap, but ESX requires a virtual machine to use his 'balloon' driver to lead you to the top of RAM internal and fool the operating system into thinking that he MUST use internal swap. It is probably where you are confused.

  The use of the RAM that you see is the virtual machine, taking all THE RAM of the host.  If the host has say 48GB of RAM, and you have the run of the 10 mV, which is more than 20 GB of RAM in use.  There is a LOT of RAM left other virtual machines, so in this case, the memory of the host is high (use), but not ACTIVE, which means allocated for the virtual machine, but the OS is not really 'use' for the moment.

  When you add multiple virtual machines, you will see this fall.  Keep in mind they can really share the memory too, so among those 20 VM with VM similar (like Windows), they are all windows (suggests) and 30% of that share these 20 VM, so 30% 20 GB is 7 GB, so 13 GB that is actually used, so in a perfect world, ideal conditions your host should be about 15 GB used probably less active 6 GB, but EACH VM shows 2 GB of memory host, right?

  It's normal.  When one approaches the limit of host memory that these figures will change, from OS and need and that the BONE... and to complicate things even more, reservations and VM limits and priority will ALSO skew the numbers.

  Isn't fun ESX?

• 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

  Check which of the VM who use high also, you can decrease the RAM of the other virtual machines that use fewer resources and set their priority action HIGH under the location of the memory of the virtual computer.

  Right click on the vm and Edit > click on share option and chenge memory to high HEAT.

• Need to move virtual machines and power over the other ESXi HA and issues of Configuration of power

  Dears

  Need to move virtual machines and power on ESXi others using the HA and Power Options

  So what are the Options I need activate and deactivate:

  Turn on Vsphere HA

  Activate the tracking host

  Admission control (disabled)

  VM Machine Options

  VM restart priority (medium)

  Response from the host of off the power isolation

  VM monitoring (people with disabilities)

  Monitoring of (high) sensitivity

  Heartbeat of data store (select one of cluster data warehouses taking into account my preferences) of the data store is checked

  On each:

  Start/stop of the virtual machine is turned off

  Please indicate the required Options and on virtual machines, we are not turning on?

  Just to be clear, that VMware HA will only restart the VMS if ESXi hosts fails - or surveillance of the VM is turned on which will be monitors VMs will they crash or suspend and restart the virtual machine affected.

  and just to be clear, that the response of insulation parameter has nothing to do whther THAT HA will work or not - it does come into play if the ESXi host is isolated of the HA - Cluster

  xMotion works only between active ESXi hosts that can communicate with the server vCenter - and if the ESXi host broke down or became isolated and vMotion may not work.

  vMotion is automated with DRS that vMotion will a VM who need more resources to an ESXi host with enough reosurces.

• How to know from a virtual machine is power off?

  Hi all

  I want to know if it is possible to find it on the database or somewhere else a parameter allowing to know since when a Virtual Machine is power off.

  In fact, I want to analyze what Virtual Machine are not used and since when...

  My level = vSphere4.1

  TKS

  It's strange, that I always find VmPoweredOffEvent entries, even when the user has launched a stop from in the guest OS.

  You can easily test.

  • Make a stop of in a guest
  • When the virtual machine is turned off, do

  Get-VIEvent -Start (Get-Date).AddMinutes(-30) -Entity MyVM | Select CreatedTime,@{N="Event";E={$_.GetType().Name}}

• I use a database program in a number of previous versions of windows and windows 7 does not allow the program to launch denial of service.

  Application of program compatibility does not start

  I use a database program in a number of previous versions of windows and windows 7 does not allow the program to launch denial of service.  What gives?

  If you have Windows 7 64 bit without BACK program can run because there is no 16-bit subsystem to run it.

  Try dosbox http://www.dosbox.com/. If that won't work your program, you'll need either a new database or run the BACK or on a 32-bit version of Windows in a virtual machine like VirtualBox https://www.virtualbox.org/.

  Hello

  Welcome to the VMware communities forum.

  Unfortunately Apple does not allow to run a virtual mac OS X on non-Apple brand hardware.

  Because this violates Apple EULA (and as such VMware Community terms of use), the problems you have with trying to run OS X using VMware Workstation cannot be discussed in this forum.

  Hope you understand,

• If someone could correct? 'Windows 7.vmx' is not a valid virtual machine configuration file

  Hello world

  I seem to have what seems to be a fairly common problem. "I try to boot my windows 7 VM and I get this error message: '/Users/.../Documents/Virtual Machines.localized/Windows 7.vmwarevm/Windows 7.vmx' is not a valid virtual machine configuration file.

  Someone would be nice enough to make me a new windows7.vmx file? I saw in other places around here, but I don't know how to do it myself. I enclose the .log files and my windows7.vmx file, so a snapshot of the folder "contents of packaging.

  Thank you so, so much! I wish bake you cookies, but unfortunately their delivery might be a bit complicated

  Have a look here - which will have to explain how do it yourself

• Can not see a virtual machine server connection mode

  Hello

  I'm testing VMWare View and I have a problem. I installed the ESX, vCenter and the view connection server. I have installed a virtual Windows XP machine and installed VMWare Tools + Agent and can not see this virtual machine when I want to create a "individual desktop" under "Desktop and pools. The connection to the vCenter works very well.

  Any ideas?

  Concerning

  Are the other machines available when you try to add an invidiaul machine?  I was wondering if you virtual center connectivity is working properly.

• Windows Vista.vmx' is not a valid virtual machine configuration file

  I just powered up VMWare Fusion running Windows Vista and got the error "/ Users / my name/Documents/Virtual Machines / Windows Vista.vmwarevm / Windows Vista.vmx ' is not a valid virtual machine configuration file

  It worked fine earlier today.

  I saw where WoodyZ aida veganjustice apparently this same problem in July.  If you need me to take a screenshot of the Virtual Machine Bundle package, please explain how to do because I'm not technically literate.  But I need this to work!

  The attached file "Windows Vista.vmx" created the vmware - 0.log.  Simply place the attached file in the Document of Virtual Machine Package, and you should be good to go.

• Satellite L100-120: Wlan does not allow the transmission of large data packets

  Satellite L100-120, Intel 3945ABG.
  Router Wi - fi is 3COM OfficeConnect Wireless, same problem with Dlink DI-524.

  By default my wi - fi card does not allow the transmission of packets of data.

  I use ping-f-l 1464 192.168.1.1 to check if it is possible to send a large package. All packages more then 600 large fail to be sent.

  It is tragically wireless performance and I almost cannot use internet at all. I solved the problem partially by setting the MTU to map wi - fi at 548. Connection is now stable, although I can not yet send massive emails. Anyway, it is not a good situation to have such a low MTU value.

  Everybody respected this problem?
