• Basic QS:-a virtual machine can share the memory of the 2 hosts?

  Hello

  I am very new to VMWare ESX, but looking at the docs, it seems that there is a possibility to create pools of resources by consolidating physical ESX Server hardware.

  However, it is not clear if a SINGLE virtual machine can run on multiple physical hosts?

  I have 2 physical servers:-each with 4 GB of RAM in a single pool of resources.

  Can I then run a virtual machine and assign it 8 GB? (and actually use up to 7 GB?)

  I'm güssing it is not possible to do...

  No, a guest can run on two physical hosts at the same time. It cannot use the resources provided by an ESX host.

  Resource with Betclic let you group all the resources of all ESX servers with this pool.

  Let's say you have two ESX servers with 3.6 GHz each. So your pool has 7.2 GHz available for its guests in this pool. However, this isn't a contignous resource, it is cut in two on two ESX hosts.

  Also, if you can, do not use resource pools. He must know exactly what you're doing, and it is a good source to make worse things running.

  The best resource on hand programmer is ESX itself. If you have a license to DRS use. According to our experience, it is very good by spreading the load on your ESX farm. If you want to set restrictions to the guests I would level comments.

• You can edit vmx files on multiple virtual machines in a cluster to allow changes of setting delay start via RCLI or Toolkit VI?

  You can edit vmx files on multiple virtual machines in a cluster to allow changes of setting delay start via RCLI or Toolkit VI? How?

  SAs desire a lead time of 10 seconds through the virtual company composed of several VCs with multiple data centers and clusters.

  Known: we can edit the .vmx file and add: bios.bootDelay = "10000" this adds stunted ms 10000 (10 seconds) when starting

  Known: we may have to re-register or some other mechanism to apply the changes to the start on the VMS settings

  Has anyone tried to make a change of large company to bootDelay on VMS? Any help?

• Is it Possible to access only bypassed FC HBA to multiple virtual machines

  Hello

  I have a FC HBA on my 5.5 ESX. Server. It does not support the function of SR - IOV. Is it possible to access this FC HBA across multiple virtual machines?

  If possible, please provide as follows to go further.

  Kind regards

  Aashish

  It is not possible. The basic material underlying PCI specification does not have a single shared between several independent operating systems PCI device.

  SR - IOV solves by creating the virtual function peripheral PCI, but as you mentioned, that he can't stand not and first of all, ESXi supports that SR - IOV for Ethernet network devices and not for native FC HBA (excluded FCoE) functions.

  Hello

  I am a beginner in vCO, I completed the installation and configuration with success and I started to create workflows, but I guess that I need help with an example that I started yesterday:

  I am creating several virtual machines at the same time, I mean all the user have to do is say how VMs, he wants to be created and the workflow must do the rest, but I don't know what is the best way to do so, in the present workflow in the library , find us only 'create simple VM' so I added a few scriptable tasks to this workflow, but still can't do what I want.

  Any solution plese? or a few best practices to perform this type of workflow? Maybe I missed a workflow can create multiple virtual machines with different names but the same configuration.

  Thank you

  Yes, you are right.

  By specifying the param -VM (Get - VM $modelVM) , you create the new virtual machine from an existing one.

  Just change the cmdlet New - VM settings according to your needs and let the VM - far.

  It creates your virtual machines based on a template and specification of customization.

  $esxName = "prodh1.MYDOMAIN.local"
  $template = "W2K8R2SP1"
  $datastore = "IOMEGA"
  $newVmList = "TEST-SRV01", "TEST-SRV02", "TEST-SRV03", "TEST-SRV04"
  $custSpec = "W2K8R2SP1"
  $location = "_Tobedeleted"
  $taskTab = @{}
  
  # Create all the VMs specified in $newVmList
  foreach($Name in $newVmList) {
       $taskTab[(New-VM -Name $Name -VMHost (Get-VMHost -Name $esxName) -Template $template -Datastore $datastore -OSCustomizationSpec $custSpec -Location $location -RunAsync).Id] = $Name
  }
  

  Of course, you can write it as before. You will need to only change the $newVmList variable in the original script.

  foreach($Name in $newVmList) {
       $taskTab[(New-VM -Name $Name -VMHost "prodh1.MYDOMAIN.local" -Template" W2K8R2SP1" -Datastore" IOMEGA" -OSCustomizationSpec "W2K8R2SP1" -Location "_Tobedeleted" -RunAsync).Id] = $Name
  }
  

  You will also need to insert the remaining part with the while loop and the customizations in your network!

• Script to create multiple virtual machines model works is not for the network adapter variable

  We are working on a script to create multiple virtual machines from a template. The script works fine, but when we try to include commands to set the NIC to a group of specific ports on a dvswitch script errors on. Here's what we have so far. This script (less network variables) works, but we would like to include the network configs in the script as well.

  -------------------

  This is the part of the script that configures the network/dvswitch adapter... but does not work properly.

  $myResourcePool = get-ResourcePool-name DQOL

  $dsName = get-Datastore-name "DQOL-DS01.

  $myTemplate = get-Template-name "DQVTemplate".

  $distributedSwitchPortGroup = get-VirtualSwitch-distributed - name "CVE-dvS04-Nexus - k 5 | Get-VirtualPortGroup-name '979-DQ-SHARED '.

  New-VM-name MyVM1-model $myTemplate - Networkname ResourcePool - $myResourcePool - OSCustomizationSpec $mySpecification $distributedSwitchPortGroup - Datastore

  (Get-$dsName data store)

  New-VM-name MyVM2-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  _____________________

  !!!!!!!  This part works, but without specifying a network/dvswitch... card!

  $myResourcePool = get-ResourcePool-name DQOL

  $dsName = get-Datastore-name "CVE-SAN-ISG-DS02-02ef.

  $myTemplate = get-Template-name "DQVTemplate".

  New-VM-name MyVM3-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  New-VM-name MyVM4-model $myTemplate - ResourcePool $myResourcePool - OSCustomizationSpec $mySpecification - Datastore (Get-$dsName data store)

  Here is the error we get:

  New-VM: all parameters can be resolved by using the specified named parameters.

  C:\Users\capuanoj\Desktop\Create-multiplevms-fromtemplate.ps1:6 char: 7

  + New-VM < < < <-name MyVM1-model $myTemplate - Networkname $distributedSwitchPortGroup - ResourcePool

  + CategoryInfo: InvalidArgument: (:)) [new-VM], ParameterBindingException)

  + FullyQualifiedErrorId: AmbiguousParameterSet, VMware.VimAutomation.ViCore.Cmdlets.Commands.NewVM

  You cannot use the - model and Networkname - parameters of the cmdlet New - VM in a single order, because both are in different parameter sets. You must first create the virtual machine and then use the cmdlet Set-NetworkAdapter to change the portgroup of the virtual machine. As in example 4, assistance from cmdlet Set-NIC:

  --------------  Example 4 --------------

  C:\PS>$myNetworkAdapters = Get - VM | Get-NetworkAdapter-name "NIC 1.
  $myVDPortGroup = get-VDPortgroup-name MyVDPortGroup
  Together-NetworkAdapter NetworkAdapter - $myNetworkAdapters - $myVDPortGroup Portgroup

  Retrieves all network named "NIC 1" cards of all virtual machines and connects to the specified distributed port group.

• What is the advantage to affect multiple virtual machines in a data store?

  Hello

  Quite a question stupid and basic, but I can't answer . What is the advantage of having multiple virtual machines in a store of VMFS data instead of having each VM in another VMFS data store? (eg. 3 VMs in 1 data store or 3 data warehouses and each virtual machine in one of them). I can only think about the ease of management for storage administrator because it creates only a single large LUN.
  
  Thank you

  By allowing multiple virtual machines in a data store, you can run more than 256 virtual machines in a DRS cluster.

  As a host has a limit of 256 scsi identification numbers, which means that it accesses no more than 255 LUNS shared. 1 scsi ID is used for local storage.

  In a DRS cluster as each host must be mapped to the same data warehouses to ensure that virtual machines can be moved on the cluster and run on any of the hosts.

  Now in my life as an architect VMware PSO I saw that a lot of virtual machines that require a single data store. The main reason to isolate a virtual machine on a data store must provide sufficient i/o performance. This can be achieved with other solutions than to isolate a virtual machine on a data store. Having a properly architected storage subsystem is crucial, vSphere can get out of a very large number of the IOPS / s. With technologies such as SIOC and DRS for storage, you can check that the virtual machines receive IO performance according to the needs.

• Cannot start multiple virtual machines.  Maybe I corrupted the model

  We had problems with disk space, and I was looking around to see if he had left garbage data store.  I am very new to VM, but even though I'm new I'm responsible for helping maintain.  So I learn a lesson the hard way.

  I found a number of virtual machines in organized which did not seem to relate to existing models.  For example, we have a model name 000729-Server2008 Server 2008, that they are in lm401\729.  But it appers to be a clone of 729 to lm401\16.  I'm going to guess that 16 was the original version and changes or clones have been made for him and we are now sitting to 729.

  Then I moved 16 in another data store, but it failed because there is a lock on the hard master.  So I moved everything back.  Now, when we try to start up of VMs driven from this model we get "file & lt; filename not specified & gt; not found"I went back and tried to deploy and supply on the model but I get

  Impossible to deploy virtual machines in the pool of resources 'resgroup-131.

  • Not to feed one or more virtual machines.

  • Error when powering on a virtual machine '2008 X 86'.

  • Cannot power on the operation on a virtual machine
    carried out because one of the files is locked. Consolidation of the
    virtual machine can solve this problem.

  • The operation cannot be performed because a file is locked.

  So I cancelled and tried to consolidate while I get

  Host '172.31.7.111' reported an error. A disk error has occurred: the parent of this virtual disk could not be opened. Host '172.31.7.111' reported an error. A disk error has occurred: the parent of this virtual disk could not be opened.

• Single VMDK for multiple virtual machines in esx3.5?

  Hello

  Is it possible to use a single VMDK to host several VM in ESX3.5 or is this feature on the way?  I think the vmware view tech that allows you to host multiple virtual machines to a single image and store only the deltas for VMS replca.

  We organize several ts who are about 12 GB per image, and each server is essentially the same.  It would reduce the space if these could be consolidated at the level of vmware.

  Thank you very much.

  What you are referring to the notion of linked Clones, it's something completely different to share a single VMDK.  with linked clones, you actually run mulitple copies of a single Machine.  This fuinctionality is not available in ESX Raw but is a characteristic of Lab Manager and VMware View Premium.

• NLB - two virtual machines can't ping eachother when on separate hosts

  Greetings,

  I've been running some tests with NLB on the different desks as recommended here:

  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1006558 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912404 & StateID = 0% 200% 2041454115

  http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1006778 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912404 & StateID = 0% 200% 2041454115

  I found that Unicast works better in our network environment, but it is still a problem:

  In http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1006580 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912690 & StateID = 0% 200% 2041454807

  He says: "since all hosts in the cluster have the same IP Address and the same MAC address, there is no communication possible inter-hote between the hosts configured in unicast mode.» A second NETWORK adapter is required for any other host communication. »

  However, even with a second NETWORK adapter the virtual machines cannot ping eachother when they are on a different esx host. When they are on the same host esx virtual machines can ping each other. Also, when they are on different hosts, so that a virtual machine cannot reach each other on their dedicated IP address, virtual machines can reach other when ping the second card NETWORK (the one without an informed gateway).

  For example, the next 2 guests are connected unicast:

  VM1 has 2 network cards, NIC1 = 172.18.18.41 with gateway (dedicated IP) and NIC2 = 172.18.18.43 without gateway / WLBS enabled.

  VM2 has 2 network cards, NIC1 = 172.18.18.42 with gateway (dedicated IP) and NIC2 = 172.18.18.44 without gateway / WLBS enabled.

  When on the same ESX host VM1 can reach VM2 on 172.18.18.42 and 172.18.18.44, and vice versa.

  When on ESX different hosts VM1 cannot reach VM2 on 172.18.18.42 but it can reach VM2 thanks 172.18.18.44. In this case VM2 cannot reach VM1 on 172.18.18.41 but can reach VM1 on 172.18.18.43.

  I followed and applied the settings recommended in this article: http://KB.VMware.com/selfservice/microsites/search.do?cmd=displayKC & docType = kc & externalId = 1556 & sliceId = 1 & docTypeID = DT_KB_1_1 & dialogID = 42912404 & StateID = 0% 200% 2041454115

  I even tried the kb from microsoft as shown here: http://support.Microsoft.com/kb/898867 even if the virtual machines have 2 network cards, but of course that did not help either.

  Does anyone have an idea what is happening here?

  The fact that it works on the same host, but not on different hosts type advanced to a network within VMware issue.

  Thanks in advance,

  Bram

  It seems that ir can be a problem of IP routing, even with the hosts on the same subnet.  Make sure that your routing table that traffic on each that is to/from your mgmt that ips turns off your local management interface.  If it isn't, then update your routing table in order to.

  Or, you could try setting up your mgmt network cards on a different subnet from your IP NLB.  I suspect that this will solve the problem.

• Unable to connect to use Windows XP mode on a Virtual Machine, cannot share files between the Virtual Machine and host

  Because of the need to run some XP programs, I ordered Win7 Pro and installed a Virtual Machine with XP Mode.

  Managed to get it going somehow, but does not connect to my home network (can't see any other computers, which seems to be common with the host of Win 7, but here, I managed to install quick links to other computers - they will not work in XP Mode), even if the Internet connection is working perfectly.

  In addition, I can't find a way to share files with the host country, drive C appears to be different from that of the hosts with no common points (where it is currently stored beats me).

  I can access a USB key, but only at a price to make it unavailable to the host and the attempt to release his capture when running XP Mode failed.

• is it possible to virtual machines in branch of common root frozen in time?

  Hello... I assume that this is possible, but I don't know how to do it.

  Example: Via VMware Server 2 running on Windows Server 2003 SP3.

  I installed Windows XP Pro SP2. Then, I used Windows Update

  update the virtual machine Windows XP Pro SP3.

  I'm writing this, I install the 27 updates from Windows Update.

  Finally, I end up with a Windows XP Pro SP3, which is until today.

  I'll use it to test different software and test web sites that I create.

  So, ideally, I would like to limit the amount of software that I

  install Windows XP Pro SP3 on top.

  I want to have the computer as clean as possible at any given time.

  At the same time, it takes a substantial amount of space hard disk to a virtual machine.

  That's my ideal goal: the 'ready to go' Windows XP Pro SP3 do a basic building block

  for computers of type variant. Lets call it base. I wish I had these example environments:

  COREa =. CORE + OpenOffice

  COREb =. CORE + Microsoft Office 2007

  COREc =. CORE + Microsoft Office 2003

  Thicket is. Base + Visual Studio 2008

  and so on

  In this way, for example, I avoid conflicts between Microsoft Office 2007 and Microsoft Office 2003.

  Since COREa, COREb, etc., all have a common core , I could probably save a

  significant amount of hard disk space.

  QUESTIONS:

  (b) If Yes to (a) above, what are the benefits?

  (c) If Yes to (a) above, what are the disadvantages?

  Thank you.

  Gerry, you're on the right track. Here are the steps that I have spend to do:

  • Import a Standalone VM

  • Select the vmx virtual machine configuration file

  • Import the virtual machine to a 'Workstation virtual VMware Machine' (still works with VMware Server)

  • Name of the new virtual machine, choose the location and version of VMware, it is created for

  • Choose 'create a linked Clone '.

  Importing VMware 2.0 is a plu product and will not work with the new Version 7 virtual computers used in VMware Server v2.0. When you create your VM Image 'base', make sure you specify the version 4 of material in the options of "product Compativility. If your VM is already Virtual Hardware Version 7, you can create a new virtual machine to hardware v4, and then it's a hard drive with the virtual v7 machine.

  I haven't used VMware vCenter importer, so I don't know if it will do so, but I don't think that VMware Convert (which replaces importing vCenter) could do, so I think we can be stuck with the help of the old importer during the creation of related clones.

  Once I have create my first linked clone VM, I put aside as a template, so I can create more clones related simply by copying its files without having to use VMware importer again. You just make sure NEVER start the original VM that linked clones have been created since (unless you want to.) Any change in disk hard of the references will cancel all related clones.

  It would be possible to upgrade the VM basis and related to virtual hardware v7 later clones, but I have not tested this way.
