• The ESX host and 64-bit

  Hello

  I am developing an ESX solution, and because of the budget and space constrants just gave me a single server.  I installed ESX 4.0 on this server, and then I created virtual machines that have become the ESX 3.5 servers.  I was able to raise virtual machines to power and run in the nested virtual machines.  My problem is, now I'm developing a solution ESX 4.0, but we use Windows 2008 64bi.  Does anyone know how to get a host internal 64-bit to be able to run on an ESX 4.0 host externally.

  Here is a small representation of the environment:

  Physical box ESX 4.0

  -Virtual Server ESX 4.0

  -Nested virtual Windows 2008 64 bit server

  Does anyone know how to get the 64-bit of Windows 2008 Server to run on virtual server ESX 4.0.  I've already activated VT on ESX 4.0 virtual settings, but I can't find a place in the Virtual Machine BIOS to enable VT any help would be greatly appreciated.

  Material assistance (VT) is not virtualized.  Thus, nested virtual machines cannot be 64-bit and is the reason why you don't see VT options in the BIOS of the virtual machine .

  If I read you correctly, you have ESX4 installed on bare metal and you have ESX 3.5 VMs.  Now that you are trying to create a virtual machine in 64-bit Windows.  You can create them in the ESX 3.5 environment.  You must create a virtual ESX4 machine.  (IOW, not nested).

  In addition, after you enable VT in physical BIOS, you must turn off the physical machine.  (Not just restart.  (Power off).

• Connect the ESX host and data store on another ESX host

  Hello

  assuming for this scenario:

  Host ESX 1: esx1

  Host ESX 2: esx2

  It is possible to mount esx2 datastore in esx1? (For example: via NFS). Of course, it is possible use a NAS/SAN intermediary, but I wonder if it is possible to achieve a direct mount.

  Thank you

  Eddie

  Well, to allow another host to share the local data store, the host must be able to act as an NFS server. The problem is, there is no service in one of the ESX version which able to serve that. So, as said what a.p., no, is not possible.

• Closing of the ESX host and conduct reviews

  Hello

  What happens to guests when the ESX4 host will be via vCLI command. Is the powerdown for the guests, save or critical?

  Kind regards...

  Wiwa53

  You must configure this on "Configuration > VM works / stop" option. You can make a different policy for each virtual machine or one for all.

  Through the vCLI are as you have made a stop in the vSPhere Client, so the system VMs will follow the order you configured in the configuration above.

• Grant Web access to the only vm on the esx host

  I have read the Administrator's guide and spent a few hours online on this subject and other types of users doing the same thing...

  I have 2.5 VC and ESX 3.5 by running very well.  I want to give web access to a virtual machine #1 running on ESX #1 host in this species, using the URL for the console "generate".

  I went VC and granted permission to the user of the Virtual Machine to the particular user I want to access the virtual machine.  I granted this permission to the esx host and the virtual machine.  When the user attempts to connect (this is a domain account) they get the connection failed due to bad user name or password.  It seems that the only account that can connect to web access is the root on this esx host account.  I am at a loss here, because I also tried to set this user as an administrator and so on.  The only account that can connect to web access, is that the account root localhost.

  What I'm missing here?

  The user attempts to access Web Access to the ESX Server? Which is what I think they do because without a third party tool they will be able to authenticate users who are in the service console, including the roots.  If they try to access Web App of VC by pointing a browser VC while they should AD credentials to access their virtual computer.

  Another thing to remember is that permissions in VC only apply when you log in to VC

• Exclude the host and guests of vFoglight

  I would like to know if there is an easy way to exclude a single ESX host and guests of vFoglight. I have a crowd noisy lab (w / 40 guests) I want to exclude from dashboards, alerts, reports, etc.
  Is there a simple way to do this?

• HA does not not as expected on the ESX host

  Hello

  I have a cluster with ESX 3 (v3.5 Update4) node that is configured to use HA & Drs During a practice session to the ESX host that I found that if I simulate a hard failure of one of the nodes in the cluster, ESX all guests arriving to run on this host VM will automatically starts not themselves on another ESX host after x amount of time. What I've done so far to solve problems is the following:

  1. allowed Virtual Machine put in power under the Configuration tab on each ESX host. Then, I moved that no matter what VM Autostart submenu in there appearing. This step is repeated on each ESX host

  One thing to note after that: when the host has been stopped, the virtual machine would properly failover to another ESX host but not itself power on. I got feed manually on the client.

  2. I disabled the resource constraints under the Cluster Edition settings Menu to enable the machine to power on no matter what

  There is nothing to change the question

  3. I fiddled with the priority of restarting the virtual machine in question to see if it would help, but it made no difference

  4. I enabled Virtual Machine control and settings left to 'High '.

  It has nothing

  There are two messages that I keep seeing in the case where the window of the Cluster:

  Failure of failover for the guest in question Warning Message

  Not enough resources for the warning of the cluster failover

  There are many resources available, so I do not know whence this second message. DNS seems in good condition I can solve the hosts & guests all with success in a direct and reverse search.

  My goal here is to have the guest virtual computer turn itself on one of the other guests of the ESX cluster.

  Any help would be appreciated... Thank you

  Look in "response to isolation" on setting HA. Did you put it "Leaves the virtual machine" setting turned on or turned off?

  If market, your host another try not to put the virtual machines from the virtual machines might still running on the original host, which can cause some collide ie.swap in use, the locked configuration files & etc.

• After that I changed the Duplex parameter on NIC's Service console, I am not able to connect the ESX host

  Hi all

  Please help solve my problem.

  After that I changed the Duplex parameter on NIC's Service console, I am unable to connect the ESX host. How can I reset the 100 MB NETWORK card duplex. Can someone help me please.

  Concerning

  Vijay

  Hello

  As the bulb you have two problems that are not related.

  (1) duplex setting, your switch and NIC must match. If one is assigned to auto-negotiation, then the other must be set to auto-negotiation. Personally, I tend to let auto-negotiation unless there is an absolute reason to spend. If you then turn on the both sides of the interface, the switch port and esxcfg-NICS allows you to change the duplex, etc.

  (2) passwords for root are not related to the network unless you have also run esxcfg-auth authentication remote.  The only time I saw what you have here is when the system is configured to try to authenticate remote and not locally.

  The two problems are fixable by booting into single-user mode, set the duplex and reset the password.

• Question ESXi 5.5 with turn a virtual computer: "an error was received from the ESX host turning on VM" '22 (Invalid argument)"'DiskEarly on a power Module failed.'

  Here's what happens when you try to turn it on one of my virtual machines (see also accessories):

  Error stack:

  An error was received from the ESX host turning on VM vzilla-ws2012r2e.

  Unable to start the virtual machine.

  Cannot open disk ' / vmfs/volumes/51286ca4-ef967828-664d-001b2129ad71/vzilla-ws2012r2e/vzilla-ws2012r2e_3.vmdk ' or one of the snapshot disks it depends on.

  Power DiskEarly module has failed.

  22 (invalid argument)

  This circumstance may be linked to a sata cable issue, with the possibility of temporary loss of connectivity, which could result in data loss/corruption, I realize.  It is a laboratory box.  Especially say that the 2 VMDK he complains (trying to light) is both on the grounds of a single physical disk. Data, read and written to the speaker, since the problem are very good (which indicates the wiring problem was resolved, and the VMFS5 file system seems to be in good health).

  No photos.  No related clones.  Just a 2012 Windows Server based VM, with several drive letters in, with those underlying files VMDK residing on different stores of data VMFS5.  Implemented end (these drives aren't really so huge), but far from running out of physical space for the data either. Everything is working great for months, until today, trying to it turns on again.

  You are looking for:

  "Failure error disk beginning module lit" results in this article:

  which indicates the .lck files may be present.  It does not exist.

  Then upwards, of a variety of other items:

  but alas, none of them seem to relate directly, or exactly.  My vmware.log file is attached below, as well as some screenshots of to show the structure of the unity of this virtual machine.  Hoping that this post proves fruitful, if anyone has had a similar situation.  The data at stake here are (mostly) redundant, but I would rather understand my way of it, in the case where it happens to me again, or can help others.  Many preferred rather than give up, reformat the VMFS and start again.

  Thank you!

  Good news, the best result I could hope. No data is lost. No corruption of the VMFS or NTFS don't drive in the virtual machine. Nice!  Saved me a few terabytes of data restoration and learned a little more on file system of troubleshooting along the way.

  It took a technician of VMware Service excellent, attentive, methodical remote 2 hours in a WebEx previously to resolve problems with these 2 files vmdk manually, because he found that there is a lock on them. I opened a request of Service (SR) # with VMware by following the instructions here:

  VMware KB: Cannot access certain files on a VMFS datastore

  To resolve this problem, apply for support from VMware Support and note this ID (1012036) Knowledge Base article in the description of the problem. For more information on the filing of a request for support, see How to submit a support request.

  I'll cover this saga and the exact process for collecting and downloading of newspapers, through to my TinkerTry.com, including the ride video.  I even captured much of the technical work that has been done. That said, it is true that little of the magic that was made to resurrect the metadata will remain a mystery, given that this piece is VMware.

  I'm ok with a bit of black box, considering how I'm happy that I got all my data, and time savings that the quick recovery represented.

• Check if the esx host is in maintenance mode

  
  Hello

  I need to know if there is a api in java vi which can let us know if any of the esx host is currently in maintenance mode?

  I know there is a way to discover this through the same monitoring using event Manager, I need to know is an api live which can let us know if the esx host is in maintaince at that precise moment?

  Thank you and best regards,

  Rachid chollet.

  Hi rachid,.

  I guess that the following property is what you are looking for: HostSystem.runtime.inMaintenanceMode

  But watch out for the docs for the property when it reads it: it is not set during the entry phase of maintenance mode.

• Naming of the ESX hosts with the underscore. Best practices?

  I was curious as to what that the general eager to name the ESX hosts with underscores "_". I found an old post in 2006 related to it:

  http://communities.vmware.com/thread/64885

  In the thread, it is usually frowend against because she not compling with DNS internet naming standards. The underscore character is not recognized by the Web servers.

  He has been wondering if there would be no advantage to include similar underscore characters with no routable ip subnets, 192.168.x, 10, etc...

  If you have designed it correctly you already have your hosts on a subnet that is not routable, so you would get no real benefit.

  Beyond this thought experiment, there are problems with your esx host with ESX, vSphere, vCenter naming universe underscores?

  Just an info

  All my guests have underscore in them. I had to replace all of them with a dashboard because ESX 4.1 will not accept underscore after upgrade to the console.

• Add more disk space for the ESX host

  Hi all

  I need to throw more disk space to my ESX hosts.  I know how to bind records in Navisphere and present to the ESX host.  Once in the VI client, I "think" I need to go to the host and do a rescan of the HBA or something like that?  I'm a little unsure of the market of part VI to add more disk space.  Could someone just point me in the right direction?  Please note that I am looking to add more disks to existing hosts in existing clusters.  It adds no storage to a new host... rather an existing one.

  Thank you

  Jonathan

  You are on the right track.  Re-scan storage card, under the configuration tab select storage adapters, select the adapter and click on the link of the new analysis.  Then go to the storage section and there should be a link in the top right of the screen that says storage Add.  Click on that and it will guide you in adding/setting in form/naming of the new disk.

• Move the ESX host again VC, VM permissions is needed

  @all:

  I have a big problem with the permissions on the virtual machine.

  Due to the fact that I created a new VC, I want to spend the ESX host for the new Victoria Cross. No problem, but it the individual permissions for VM to disappear.

  Well, I'm looking for a script powershell read/grouping, the name of the virtual machine and the permission is assigned (like the tab authorization VC). After the removal of the host, I would like to add the permissions to the virtual machine.

  Probably something with "AuthorizationManager" but I can't make it work...

  Any help is appreciated

  THX

  If you want to only read permissions for virtual machines in a specific data center do you it like this

  $serviceInstance = get-view ServiceInstance
  $authMgr = get-view $serviceInstance.Content.authorizationManager
  $report =@()
  
  # Read and list all permissions for VMs in Datacenter
  Get-Datacenter  | Get-VM | %{
    $entity = $_ | Get-View
    $permissions = $authMgr.RetrieveEntityPermissions($entity.MoRef, $false)
    foreach($perm in $permissions){
      $row = "" | Select VMname, Principal, Role, Group
       $row.VMname = $entity.Name
       $row.Principal = $perm.Principal
       foreach($role in $authMgr.RoleList){
         if($perm.RoleId -eq $role.RoleId){
          $row.Role = $role.Info.Label
            break
         }
       }
       $row.Group = $perm.Group
      $report += $row
    }
  }

• How to add a new virtual machine to the ESX host using the existing files?

  I need to implement a function clone without the use of cloneVM_task. I copied (a special copy) a set existing VM Directory Active Directory to a new directory and renamed copied all files prefix name of the new direcotry.  What task VM (reconfigVM_task, createVM_task or registerVM_task) command can I use to add that the new copied VM on the ESX host? I need to manually update the .vmx for new UUID file and other parameters?

  Thanks for any help.

  I think that as long as you have updated all the names to reflect the new clone you must be fine and on the first step, you will be prompted with a question.
