• What is the interval of time between the virtual machine Linux and ESXi host synchronization?

  I have ESX5.0 with a centos6 installed on this linux virtual machine.

  After the installation of vmware for Linux virtual machine tools, I activated the time synchronization between the virtual machine linux and ESXi host through vmware-toolbox-cmd.

  I wonder what is the interval of time between the virtual machine linux and ESXi host synchronization? If I quickly time OS system, when the OS system time will sync back to the ESXi host?

  According to http://www.vmware.com/files/pdf/techpaper/Timekeeping-In-VirtualMachines.pdf:

  By default, the demon checks the guest only once per minute operating system clock.

  However, depending on whether the guest is behind or in front of the result is different. So, please read the section "periodic synchronization" (at least) in the document mentioned above.

• Change the path information for ESX ESXi hosts to access

  Hello all! I hope you guys can help me.

  I have about 47 hosts that I need to change it Round Robin storage path information. If I make the change in vCenter and restart the host it again changing fixed. So, I thought that I should change it to the level of the host through esxicli.

  I have about twice as many LUNS of the Hitachi SAN. I'd like to see if it is possible to make the change in all areas, in some way, or I need to make the change by host? Also, is there anything that I need to change sides San so that it works or not.

  I saw this VMware KB: modification of path information for ESX/ESXi hosts to access and assume that it is the best plan? But did not know of all put into custody, if necessary, that everyone ran to when doing this?

  You will need to make the change by the host and the KB you'll find is the right method.

• Director of the laboratory - cannot export to ESXi host (SMBMount unsupported)

  Hi all

  I had this problem since the liberation.  This is my environment:

  Director of the laboratory of 4.0.1

  vCenter 4.0 Update 1

  ESXi (3 guests) 4.0 Update 1

  Shared storage: EMC SAN with NAS volume on gigabit ethernet.

  I opted to use on ESX ESXi VMWare's future, as far as development.

  My problem is this: when I click to export a configuration of Lab Manager, it fails with "Error in export."  The details of the message are:

  * Error export the Configuration.

  vCenter Lab Manager cannot find that any suitable host connected to the "NFS Datastore" data store for this operation.

  Host 'ESXi1' is an ESXi host and does not support smbmount.*

  I installed ESXi being under the impression he was supposed to have all the same functionality as ESX.  Now, I have myself screwed... my users will sometimes have to export configurations to test booting the VMS of USB dongles (as there is no USB transfer directly to a virtual computer that it's time to start).  If at least 3 times a week I have to export virtual machines, one by one, to a network share, which is quite tedious and quite annoying.

  Is on the timeline of development?  I noticed that the 4.0.2 has been released, but by its requirements (http://www.vmware.com/support/labmanager40/doc/releasenotes_labmanager402.html#newfeatures) it does not support ESXi 4.x, which is strange because the requirements for Lab Manager 4.0.1 (http://www.vmware.com/support/labmanager40/doc/releasenotes_labmanager40.html) list ESXi 4.0 as a host in charge.

  Can someone please shed some light on this issue and maybe get it on the development plan for the next version of Lab Manager?

  Thank you!

  stemplar,

  We don't do generally no update notes version after a product has been released.

  In addition, it is not specific to Lab Manager, ESXi does not support required... orders so Lab Manager is just stating the restriction of resource pools provided.  As far as I remember, ESXi did not support smbmount (or mount-t smbfs) since its inception.

• vCenter crashes when you add esxi hosts

  When I add an esxi host to vcenter, it crashes when it comes to installing the agent vcenter at the bottom of the screen. Then my vi client will expire and say he lost the connection. What of weird is that my vcenter is just a virtual machine sitting inside the physical esxi server, I am trying to add. My connection is both high speed broadband as well. I don't understand not for vcenter IN the esxi server, I try to add, you would think that the connection should be fairly quick. My vcenter vm using windows xp pro 32-bit.

  When you run the add in vCenter you are connected to the local ESX and vCenter through the vSphere client?  I don't think that cause this problem, but if you are connected to two, during the add, delete the vSphere client connection in the ESX and try to add it again.  In addition, if you publish newspapers at the time of failure:

  ESX

  / var/log/vmkwarning

  / var/log/VMkernel

  var

  vCenter

  Journal of vpxd

  Is this the only ESX add that causes the problem?  You can VMotion the vCenter to another ESX Server and try to add the ESX problem?

• Configure a backup at the request of 5.0 ESXi hosts

  Hello

  Is there anyway that I can configure a scheduled backup of 10 servers ESXi?

  Please suggest.

  Thank you

  Mihir

  Mihir salvation,

  Years ago I was also thinking around how to manage the ESX (i) to return once crashing.

  I could circle in all directions, but I come to the end that "try to save some configs" > theire is of single Point of failure.

  -Get 100% of all the files that are needed to get the config back once that crashing

  -At a Major relase change > perhaps this dependend files modification or extension

  -Restore/backup Configs, maybe causing a kind of instability...

  -Don't know if Vmware supports 100% backup and restore config

  In any case, my own Solution follows.

  Instead of save config and trying to restore > I kill 2 flies with 1 slap.

  -Fast food (but of the mind, this is a new installation and pushing scripts,...)

  -Update of the process. (New installation with the new Build number)

  I use the PXE boot solution.

  The server is much more stable.

  What I did:

  -R2 Windows 2012 with IIS + WDS

  -With the help of 2 actions

  1 x for WDS

  1 x for IIS

  IIS part = 1: Hostcfgs (Kickstart files for each host)

  2: Patch (placed the last update file)

  3: scripts (host, ntp file, the advanced settings, file exchanges,...)

  WDS share = deployment share of default windows where I place the iso extract binaries and files menu pxelinux.cfg,...

  Then at all. Once I have a strange problem. I push things kickstart and have following

  -More information freshly installed with all THE Configs as before

  And once that a new major Relase is out > it is easy to integrate to PXE.

  If you have only one initially effort and you need keep the patches (or by creating every time a new Source).

  PS: Remember, you must be sure that the system is Stable. And with a sort of backup/restore > you never 100% could be sure that this is the case. Because you know a lot of theire ID of the object in the background...  With this kind of Solution, I could be sure that I covered everything 100%.

  "vicfg-cfgbackup" is a good idea >, but never I would rely on it completely.

  Just Feedback to think in the other direction.

• Moving the computer a stand-alone ESXi host to vCenter virtual

  Guys,

  We have 2 VMware environment in the work.

  A production environment which consists of four hosts ESXi 4.1 managed by vCenter 4.1 with Enterprise license.

  We have a host of ESXi 4.1 stand alone with the standard free license.

  I have a Windows XP VM on the test area.  I need to make a model of the virtual machine, and then to deploy a few new VM from him.  Now, this is where the problem.  I want to do all this but having the VM running on the test area.  Of course these features are not included in the free ESXi license.

  However, I think that I could download the VMDK files in the test area, import them into vCenter and then make a model in there.  I could deploy VM from the model power vCenter them down, download VMDK files and then download on the test area.

  I'm pretty sure it's possible, but I want to just make sure.

  Thank you

  It should work. Assuming that the free host doesn't have its VM on shared storage that is also accessible on the production cluster, you can export the virtual machine to the FVO and import it in vCenter.

• Unable to start the virtual machine after Migration - ESXi hosts

  Last night I wanted to move a virtual machine to a host of test to a production cluster.  All hosts (test and production) have shared access to the same LUN, so I usually am able to simply remove the virtual machines of the inventory in the test environment and add them to the production environment by accessing the .vmx on the data store file.  Two of the 3 hosts migrate perfectly and are running in the production environment.  However, the third server, while the migration starts.

  First he gave me errors that it was missing some files.  The only thing I did was different to rename the folder for the virtual machine on the data store.  It was called 'New Virtual Machine' for a reason, so I renamed it to "Antivirus."  However, something strange happened.  Instead of renaming the folder, it seems was created a new folder named "Antivirus" and the old folder 'New Virtual Machine' was still there.  In addition, the renamed folder 'Antivirus' had only SOME of the files needed.  So I just copied from the old folder in the folder "Antivirus" and he hung up the virtual disk of 20 GB file.  So I closed the VI client and checked the vdmk 20 GB folder and back this morning is in the folder with other files.  However, when I try to start the virtual machine, I get the "cannot access a file because it is locked" error message.

  I've done some detective and I noticed that in my second datastore where was the other folder vdmk, the file was now .40kB in size.  Looks like I've lost my other vdmk folder.  What happens here?

  It looks that the virtual machine was still running when you tried to change the name, so the old folder could not be renamed because of the lock. That's why a new folder has been created instead, and why your vm hung on the vmdk file until the lock has been released. Don't know what happened to the 2nd vmdk file, but the file vmware.log in virtual machine directory must have some info as to why does not start the virtual machine. If the 2nd vmdk is gone, this might be a reason.

• The SSD drives on local ESXi hosts dilemma...

  My company went ahead and installed the SSD drives locally in each HP Server, so this basically means I can't my hosts in cluster and enjoy the HA\DRS... in my view, correct environment vMotion?  I found a few links referring to this scenario, but it was not clear if the failover will work if one of my hosts breaks down?

  I use them and set the swap file to be stored on the local host.  This save space you on your back-end SAN and reduced some IO.

  If using local storage is important for your VDI sale, I would take a peek at Nutanix, which is a host ESX SAN in a (basically they use local storage and make it work like a San that rocks.)

  I would hold these SSD at the moment, I do not know how CBRC will apply once VMware he applies fully.  If it works anything like Citrix Intellicache, then you could end by using these SSD as the volumes of local cache.  For now though I would not try and design their use.

• Quick newb question: possible to 'navigate' the file on an ESXi host computer system remotely?

  As the subject says: is it possible to 'Browse' the file system to an ESXi host through a GUI tool on the server vCenter Server, instead of having to navigate this one via e.g. puTTY?

  JH

  OK... think about it. WinSCP and enabling SSH on the host computer ESxi is the key.

• Should the RAM for an ESXi host replaced the same ones remaining?

  Hello

  We are running a cluster of servers ESXi 5.1 - 2 of them are Xeon E7440 2.4 GHz (64 GB of RAM) and 1 of them is Xeon X 5460 3.16 GHz (32 GB of RAM).

  Currently, the use of the memory of all three ESXi hosts are about 60%.

  We will replace the Xeon X 5460 server with a new physical server.  We would like to ask for your opinion how much RAM you must order (my manager of door on the cost of the new server).

  Thank you

  Hi again Tony,

  1. No, it is not high at all. You should begin to worry about this, after reaching approximately 85-90%.
  2. My short experience with clusters of memory-unbalanced, adding that more memory would be a lot like the DRS manages memory locations & 'kindness host' in the right direction, but I'm not really sure how that would turn out in the long term. If you decide to present more memory to your server, it would be possible to upgrade the other two guests sooner than later
  3. Yes, ask the seller would be the right thing to do. Please note that you will need to put in place an enhanced vMotion to conform to your next "older" CPU then, because you'll have something other than X 5460. I guess you'll have to "intensify" a generation or two, depending on what you have found.

• Migrate the replication for patching ESXi host device

  Hi guys,.
  

  
  

  I'm trying to Storage vMotion/migrate vSphere replication device to different host for ESXi patches. I get the following message
  
  "This entity is managed by VR management solution. It is not recommended to edit it directly. Instead use the GPMC for the solution if you want to make changes. You want to proceed. "
  
  I use vSpere replication without the SRM device. What is the best approach to upgrade ESXi host where there is replication Appliacce. Should I just stop then move the unit, or is it possible to move it while it is running?

  
  

  Kind regards

  Hello

  Moving the unit via the technology Vmware is perfectly fine.

  The message/warning you receive is just to warn you that this VM is a critic and you must be careful. The same message if you invoke the power out of this machine.

• ESXI hosts 5-2 and the best way to configure vSwitch and Nic redundancy

  Hi all

  Could someone help me find the best way to configure the vNetwork on 2 5 ESXI host for redundancy.  Once I managed to correctly configure the 2 hosts I will seek to use the same installation process for 6 guests.  3 sites with 2 hosts on each site managed all of vCentre Server

  I have 2 DL380 G7 servers 5 ESXI installed on a class 10, 8 GB SD card, I'm looking to install VSA on the 2 hosts on each server with 4 TB of internal storage (8 * 600 GB 10 k SAS).  Each server has a gigabit integrated 4-port NIC and I installed a 2nd NIC gigabit PCIe 4 ports, I also x 2 16 switches of port with Layer 3 routing.  I use vSphere 5 Standard acceleration Kit I am looking to use vCentre server for managing, vMotion for maintenance, HA for the failover and VM 10/15 (vCentre Server Std, DB SQL to vCentre Server, Exchange 2010, SQL Server 2008 R2, IIS Intranet, Helpdesk, 1 DC, 2 Domain Controller, AV Server, WSUS, SCCM Server, and Terminal Server server).

  What would be the best way to install and configure the network for performance and redundancy and am I missing something?

  My thoughts are, Teaming: -.

  vCenter - vswitch0 - port1 on NIC1 and port1 on NIC 2 - port1 on NIC1 to physical switch 1 - port1 on NIC2 to physical switch 2

  vMotion - vswitch1 - port2 on NIC1 and port2on NIC 2 - port2 on NIC1 to physical switch 1 - port2 on NIC2 to physical switch 2

  HA - vswitch3 - port3 on NIC1 and port3on NIC 2 - port3 on NIC1 physics 1 - port3 on NIC2 to physical switch 2 switch

  VM - vswitch4 - port4 on NIC1 and port4on NIC 2 - port4 on NIC1 to physical switch 1 - port4 on NIC2 to physical switch 2

  or do I need an additional NIC on each server to hit the VM 12-6 VM for 2 ports on 2 NETWORK interface card, or maybe something else I missed?

  Thank you

  In your case, to keep it simple and what I can say here is what would be my recommendation:

  3 standard vSwitches

  vSwitch0:

  • Management - vmnic0, vmnic2

  vSwitch1:

  • vMotion - vmnic1, vmnic3

  vSwitch2:

  • VM network - vmnic4, vmnic5, vmnic6, vmnic7

  The only reason why that I didn't split the VM in other network adapters shipped is because the difference in the types of the DL380 adapter shipped and the PCIe quad.

• Ports vmk NFS considerations when you move a host of distributed 1 switch to another

  Hi everyone, I wonder if you can help with the following...

  I currently have a number of ESX host that accompany the dvswitch0 for connectivity management and NFS.  VM networks has already been migrated to new dvswitch. The following assumptions are correct?

  I need to remove a vmnic from the current dVS, so that I can create a standard vswitch and migrate vmk0 (network management) to it before removing the host of dvswitch0?

  When I did it and I delete the host of dvSwitch0, I lose connectivity for my NFS vmk? Or will they continue to work as I have the info ip configured locally on the ESXi host? I've recreated the PG for NFS on the new dvswitch bearing the same name and config like dvswitch that I want to spend

  If the connection is lost, I guess I need to migrate a vswitch standard before removing the vDS, identical to my management network of my NFS vmk. And then migrate them all using the wizard when I add my host to the new dwswitch

  If the connectivity will not be lost, I guess when I add the new dvswitch host and migrate my vmk0, the vmk NFS will appear in the PG on the new DVS as my exchanges were confiigured with the same name?

  Is that correct the above?

  Thanks in advance

  
  

  If the connectivity will not be lost, I guess when I add the new dvswitch host and migrate my vmk0, the vmk NFS will appear in the PG on the new DVS as my exchanges were confiigured with the same name?

  As long as there is a valid vmnic attached to your destination vSwitch and a group of ports on the VLAN, the migration of your NFS vmk interface will be successful.

  I suggest doing this kind of work, while the host is in maintenance mode; There will be a small window of time during the migration where the host loses connectivity to the NFS data store.
