• How everyone counts the total amount of GHz for virtual machines on a host-cluster?

  Hello

  I want to do some basic sizing and I may\may do not go the way to write about it.  For example, suppose I have a cluster of 4 nodes with a total of 200GHz and 1 TB of RAM on all four hosts with 100 VM.  How can I get the total amount of GHz\Memory that each virtual machine is configured with (not necessaryly to aid real-time) so that I can workout or demonstrate what fits on one or two hosts in the cluster, for example?

  Thanks for your help and advice in advance

  You can do this via the inventory tool called RVTOOL which allow you to do an inventory of all your virtual machines and hosts with the resource assigned and served. hope, it will help you.

• How to change network name for all virtual machines within the same cluster

  We have recently changed name vswitch to take into account that something significant, in the past vCenter could change the labels of networh for all virtual machines... seems this time help labels are not changed (maybe its got something to do with the update vcenter for 2.5.U3)...

  in any case, someone at - it a powershell script that could find all the virtual machines that are referring to the old label network and then changing again the name... ?

  Enjoy the respponses...

  Thanks in advance

  A few things on this blog could help.

  If you know the names you want to use, you could also just use something like:

  Get-Cluster X | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "OldNetwork" } | Set-NetworkAdapter -NetworkName "NewNetwork" -confirm:$false
  Get-Cluster X | Get-VM | Get-NetworkAdapter | Where { $_.NetworkName -eq "NewNetwork" } | Set-NetworkAdapter -Connected:$true -confirm:$false
  

• Cannot start the virtual machine in a HA cluster

  I installed a HA cluster with 2 hosts configured in it.

  I disabled the admission on the cluster control.

  Each host is a Dell Dimension 9150 with 2.8 GHz CPU and 2 GB of memory.

  I created a virtual machine on a host with 1 vCPU and 512 MB memory.

  However when I try to start the virtual machine, I see the task of 'Power on a virtual machine' fail with the status "the host has sufficient memory resources to satisfy the reserve."

  Why this is happening and how do after that?

  You have the minimum RAM required by ESX ESX 4.0.

  Add more RAM to play also some virtual machines.

• How Virtual Machines to access the data over a Fibre Channel SAN network

  Hello

  I have storage EMC SAN and HBA Qlogic card installed on a server from VSphere 5

  How do I access the LUN that I created on the SAN on a virtual machine.

  Please help step by step because I am a new on VSphere

  so the trick with rdm, is that there may be any vmfs existing on it. so even if you do not want to perform a new scan, it can be mounted in the storage. delete the vmfs partition, remove it from storage, then go to add HDD on the vm again and rdm will be is greyer. Obviously im assuming that there is no data on this lun. This operation will destroy all information contained in this logical unit number since we reformmatting it.

• Using a USB dongle on a virtual machine in a HA cluster

  I need to install software on a virtual machine in ESX 4.0 cluster, which requires a USB dongle to be fixed in order to run in non-evaluation mode. I just came across a product called AnywhereUSB which seems to be supported by VMware. Can anyone tell if they used this product, it's all good and I'm still going to be able to have this quick vMotioning of VMS, as is currently?

  > I'll still be able to have this quick vMotioning of VMS, as it is currently?

  Yes. You will be able to VMotion VM with USB over IP solution.

• Is it possible to recover all the virtual machines in a cluster in a single web service call?

  I tried to retrieve the list of all virtual machines in a cluster to a single web service call, but to no avail. It seems that there is no direct web service API to achieve this goal. Alternative options must first recover the hosts or data warehouses in the cluster and then recover virtual machines from there. But still, if anyone has an idea how we can do this please let me know. All help information will be greatly appreciated.

  It is possible, if you use the PropertyCollector.

  (It is usually the answer to questions of the form "Is it possible to retrieve the X in a single web service call").

  Call"propertycollector.retrievecontents:

  http://www.VMware.com/support/developer/VC-SDK/visdk41pubs/ApiReference/vmodl.query.PropertyCollector.html#retrieveContents

  allows you to retrieve a whole bunch of stuff in a single call, which you then have to go through and interpret.

• Virtual Center stops all the virtual machines in a cluster HA

  Hello.

  I have a question about vCenter machine. We have deployed

  VMware ESX 4.0 HA cluster on Server Blade IBM 3. VCenter machine resides

  on a virtual machine on the same cluster. When we tried to recharge a physical switch (in the)

  IBM Blade Center), all our virtual machines on the cluster have been turned off automatically.

  If the vCenter VM is turned off, then everything is fine - the reloading of the

  Switch is not turning off the virtual machines (and the net is ok - start machines

  work through another switch in IBM bladecenter). If the machine vCenter

  powers (manually), all the other machines, which have been put off, are powered

  on too (automatically, of course, with the help of the machine of vCenter). How

  is that what I can adjust the machine vCenter, so it could not power power machines by

  itself automatically?

  ESX 4.0 (162856)

  Hello

  Right-click in your cluster, change the settings. Select 'Virtual Machine Options' under 'Vmware HA' and choose the host response of insulation desired for the entire cluster or individual VM. If you do not have network connections redundant between your ESX machines, you probably want the virtual machine for when you need to do maintenance or your network switch died. You should probably also disable HA while doing maintenance. You should consider to build network redundancy in the case of a production environment.

  I hope that helps!

• How to disable the HA/DRS option on a virtual machine?

  I have a virtual machine running under VMware cluster of 8 ESXi hosts. I want HA/DRS must be disabled on this virtual machine, as well as VMware may not move this vm incase of any failure. Can someone help me on this request?

  Hello Krishna,

  Yes. You can do this in the DRS and HA game settings for each virtual machine individually in cluster settings.

  There are various tabs of options HA - VM and VM - DRS in the vSphere client.

  In the new web client, these parameters are on a tab:

  Manage->-> VM overrides settings.

  Set the DRS automation level and priority to restart HA to disabled for this virtual machine. Also choose to leave it turned on like HA host Isolaiton response.

• Create virtual machines in a cluster with vCenter Lab Manager?

  Hi, I will be putting in place of Lab Manager in the near future.  I already have virtual machines in the vsphere cluster I want to start dealing with Lab manager. Should I remove these virtual machines before the implementation of labmanger?  I'll still be able to create and host virtual machines outside the sottware to labmanger, on the hosts in the cluster of Lab Manager?

  Thanks for the help

  Raymond Golden

  VCP3, VCP4, MCSA,Net, was DRY.

  Yes, you can certainly mix "regular" VM and VM Lab Manager in the same cluster.  Just Lab Manager server knows nothing about the virtual machines created in vCenter.

  You could also separate them from resource pools... Director of the laboratory can be assigned to just use a pool of resources rather than the entire cluster.

• Cluster VI3 and vSphere Cluster (migrate virtual machines)

  I have a VI3 and vSphere cluster.  Could I just drag-and - drop my virtual machines to the new Cluster or do I have to upgrade the virtual machines ' hardware of the v4 to v7?

  Thanks in advance

  1. you don't have to upgrade the virtual machine hardware, it is optional.

  2. you do not have to create new cluster, simply upgrade existing by-host. Virtual machines with hardware v4 can be VMotion'ed between 3.5 and 4.0 hosts

• Number of virtual machines per server

  This number varies greatly with the type of workload and of (among other variables) network connectivity, but what would you say is a common number of virtual machines running on a particular server (NIC10 G ) platform? 10? 20? 40? The number of sockets/cores on this server?

  Any contribution is appreciated.

  Thank you

  Hey Ex,.

  This issue of $ 1 million has been requested several times before.  The answer is simple - there is no definitive answer.  There are so many variables that contribute to the number of virtual machines, you can run on a server:

  -number of Sockets
  -Core per socket

  -CPU speed

  -Density memory

  -Bandwidth allocated by host

  -Storage connectivity & bandwidth

  -Attributes VM & function of workload (amount of memory, CPU & disk by virtual machine)

  Although you can probably squeeze a lot more virtual machines per server with densities increased memory & CPU power, also increases your default domain name.  HA may be able to 'recover' virtual machines on a failed host, but how virtual machines are you willing to lose only once?  When sizing of your hosts, also the failover capabilities take into account.  Each of your cluster hosts should be able to tolerate the failure of at LEAST one host and meet all the requirements of memory & processor of the additional virtual machines now spread over the remaining hosts in the cluster.  This is why administrators does not often grow over 60% of the capacity of their hosts.  VMware uses a calculation of size "slot" to ensure you have adequate to your cluster failover capacity.

  As typical, I see regularly around the mark of 20 VM per server on a typical 2-socket server with 96 GB of memory and dual 10 G uplinks.  It is also good to think that most software licenses (VMware, Nexus 1000v etc.) is based on the counts of socket, and since the memory is going to be your first argument point - servers that can support large amounts of memory are usually an ideal choice.  B250 is perfectly placed to virtual workloads like this, while the B230 is a little firecracker with a bit more CPU power under its hood so you need.

  As vague as I was, I hope this starts your thought process

  Kind regards

• Move the virtual machine from one host to another with shared storage

  Hello

  I have a question on how to move a virtual machine from one ESX 4 host to a host ESXi 5.  These hosts have access to the same shared storage but the ESX 4 host is outside the network and host ESXi 5 is inside the network so vMotion is not an option.  They are in different groups.  I know that there must be an easy way to move this virtual machine, but for the life of me, I can't find it.  I guess I have remove the virtual machine from the external cluster but how to make the virtual machine in the internal cluster?

  Thanks in advance...

  If both host access to the data store even where VM's store, just stop the virtual machine, remove inventory on ESXi 4, go to ESXi 5 vSphere vSphere, browse the data store where the VM is stored, do a right-click on the .vmx file and add to the inventory.

• PowerCLI script - new virtual machine of the model

  Hi all

  I am very new to power CLI scripting, and these days, that I read a lot of help to automate the creation of a new virtual machine based on the model of the virtual machine.  Script that is not that hard, even location new virtual machine on a particular data and in a particular resource pool store is not difficult.  For this I came up with this very basic script/command:

  "New-VM - ResourcePool < resource_pool > - < folder_name > location - Datastore < datastore_name > - name < VM_name > - < template_name >"model

  However, I came across some problems that I can't find information in help or in the forums.  Problem with the above command is VM will be created in the pool of appropriate resources and file as long as they are unique, but if there are multiple instances of resource pool or a folder with the same name as the script spits out a mannequin.

  So for example if I want to create a new virtual machine to the location following Data_Centre = > RootFolder1 = > SubFolder1 = > SubFolder2 and SubFolder2 name is unique that no problem, the virtual machine is created at this location.  However, if the SubFolder2 exists in Data_Centre = > RootFolder2 = > SubFolder1 as well as the virtual machine is created in the folder root of the location of the model.  For example, if the model is in "DC = > Folder1 = > Subfolder1 = > Subfolder2 ' the virtual machine will be created in the folder Folder1

  Any suggestions on how to ensure that the virtual machine is created in the desired folder/location as well as a list of resources?  In my view, there are really smart guys here and I suspect that this issue would not be a problem at all.  Any help would be appreciated.

  See you soon

  It is not a matter of following the right path.

  You can use the location setting to get the exact folder you want. For example

  $dc = get-data center-name DC1

  $folder = get-file-name Folder1-location $dc

  $subfolder = get-file-name Folder2-location $Folder1

  or

  $dc = get-data center-name DC1

  $subfolder = get-file-name Folder2-location $dc

  You will need to find a "place" in the path to your destination folder where it will be unique.
