• Virtual MACHINE starts in EFI environment after crash

  Hello world

  I'm breaking my head on something that looks like a bug to me.

  A few weeks ago, the ESXi host on that I was running VMs crushed (power fail) and after powering back and from virtual machines on this stand-alone host, one of the virtual machines did not start correctly.

  This machine virtual runs Windows Server 2012 and booted up this time in the EFI environment.

  After some research, the EFI configuration is gone. When opening the Boot Manager Maintenance upward and choose 'Start configuration Options', no options are listed. When you add a new boot option and using the backup function, the settings are lost instantly. When comparing the parameters with any other SMV 2012 I have running, Miss me a lot of configuration such as startup options and some driver options.

  These two options will not save after closing the menu for adding these options. When you choose 'Start from a file' I can start the virtual computer by using the 'VOLUME LABEL\EFI\Boot\bootx64.efi No.' file. After the virtual machine restarts, it will be to the EFI environment.

  It is very difficult to find information about the EFI BIOS so I hope anyone here have experience with it.

  I even tried to restore the VM about 2 weeks before the accident, but even with the files of the virtual machine will start in EFI environment with no settings at all. So maybe the problem caused earlier; very weird! Also not to be able to save the new settings in the environment EFI seems very strange to me.

  Thanks for the replies! =)

  Hi René,.

  Hmmm... There is something of very, very wrong with this file NVRAM.  Looks like that the power failure has corrupted the file NVRAM in a way that confuses the firmware irreparably.  I consider this new next week (next year!) when I'm back in the office and will introduce an internal bug report if I find something that we can make it more robust.

  Although I generally recommend it not for VMS EFI, in your situation, your best course of action is probably the virtual computer power off, remove the file .nvram to the directory of the virtual machine (or rename it to something else, if you want to be extra careful), and power then it powered.  A fresh .nvram file will automatically create the virtual machine starts.  For the most part, reasonably normal Windows installations, the virtual machine must then be started automatically in the operating system installed.

  (For the benefit of other readers of the forum who may come across this thread, I repeat: do not delete a virtual machine EFI NVRAM memory, unless you understand the consequences!)  "It seems that there is rather than remove the NVRAM in this particular situation and very few others.)

  Please let me know if that gets things going again!

  And I'm going to one of our regulars of the forum, WoodyZ, avoid having to make his regular situation comment: If you haven't already done so, you can consider investing in an uninterruptible power supply (UPS) to keep your system running through power cuts or to allow at least a normal instead of a hardware failure stop.

  See you soon,.

• Cannot import Microsoft Windows Server 2008 R2 with Hyper-V virtual machines to VMware ESXi 4.

  Hi team,

  I use VMware vCenter Converter Standalone to import certain Microsoft Windows Server 2008 R2 with Hyper-V virtual machines to VMware ESXi 4, using another Windows Server 2008 R2 as the machine Agent Converter. Well, the agent connects to the Windows VM source very well (I used the net use command to create a line of conduct...), perhaps no chance to connect to the computer target VMware ESxi 4 and make the converter doesn't work...

  Following is the error message:

  "Unable to connect to the host specified" from the converter agent machine. " It is perhaps because the host is not available on the network, there is a problem with the network configuration or management on this host services do not react. Check all components of converter to be able to connect.

  So, my question is; is it possible to create a work around (like the net use Windows command above) to make possible the connection of the converter Agent on Linux VMware ESXi 4 machine Windows machine, to directly import the virtual machines of Windows Hyper-V to Linux VMware?

  Thanks in advance,

  It's even easier than that

  Use this: http://www.winimage.com/

  Which will convert *.vhd *.vmdk, so you don't need to do all this... Of course, another way is to start the machines, leaving them on Hyper-V and go through the network and process virtual machine as physical machines and do a P2V on the network...

• Spectrum of HP x 360-13-4009na: Machine starts with "Preparation of auto repair. Cannot reset. "The disk is locked.

  One day the machine started start mode "Preparation of auto repair. I tried to reboot several times, including a hard reset without effect.

  Then I tried to "put this PC" but I get the message "the drive where Windows is installed is locked." Once, he did pass this screen and asked me my credentials for the Windows account but then failed. Now it's to the same message.

  I then tried of the system hard disk diagnostics. The DST short and SMART test passed BUT the long DST has failed with an error code ridiculously long...

  0LPMB9-7LT88D-MFPWMG-61V503

  My conclusion is that this problem is hard disk (SSD) related, but what I can do now.  Needless to say my warranty missed in January 2015 (I think) and the machine is currently blocked.

  Does anyone know what the code above means?

  If it's a SSD failure, how can I get it replaced and then how do I reinstall Windows 10 since HP did not provide support for recovery with the machine, either 8.1 win or win 10.

  Any help appreciated.

  Paul.

  Your long test failed.  I wouldn't replace the drive if I felt it unnecessary.

  You'd better replace but weather that you do it yourself or not, I can't comment. HP has no instructions for your model on the replacement of this player.

  If your comfortable with DIY, go ahead as long as its out of warranty.

  Specs say it has a 256 GB SSD M.2

  Personally, I would like to look at the disc before I ordered one, to make sure that I get the correct type.

  Good luck.

• Machine starts beeping and stops...

  My friend just put a Corsair 850 watt power supply in his P6404y machine and tried to stock update the 9100 Nvidia graphics card to an Nvidia GTX 460 and the machine would be fine, however when he tried to play games the machine would beep and closed which is usually a symptom of a GPU overheat condition.  He then returned the GTX460 and upgraded to a PNY GTX 470 thinking his first card was a supplier without a name and the same problem occurs.   He then put a big fan next to his computer with the side and if the machine starts to beep it makes and may continue to operate, but I told him that option is not recommended.   There is nothing in the Bios to see what the parameters are for the monitoring of heat on a GPU and there is no newspaper generated indicating what the cause of the stop is.   We looked online for help and there is none available for mother Pegatron m2n78 - made by Asus for HP.   Is there a software that allows to monitor and change settings for the beaches of heat on a GPU, or y at - it another way to identify which monitors the machine for the heat so we can try to solve this problem.   The bios options are very limited and we are really stuck on this one.   Help, please!   Thank you

  Chuck

  OK, we believe that we have solved the problem!   Even with the upgrade of the energy supply, the issue seems to be with the current Nvidia cards.   Under site Web CPUReview, they show the max of each graphics chip power draw.   Looks like the Nvidia GTX 460 drew 160 watts and the next card, we tried the Nvidia GTX 470 drew 170 watts maximum.    We tried and tried and failed to get the system working.    Now, a few months later, we were given another chance and used a card Geforce 9700 GS PCI-E and it works beautifully.   The card has not been fast enough, but he had only a maximum current of 82 watts.   Makes us think it was the fact that the GS 9700 uses DDR3 and recent Nvidia cards use DDR5, but after checking, we found that had nothing to do with the problem.   Then plunges us into the issue of tension and grabbed a new ATI Radeon HD 5450, who also ran fine and has a maximum circulation of power of 20 watts.   The map was underpowered for 3D graphics, so we then made a leap up to an ATI Radeon HD 6770 and again once it has worked very well to 108 watts.   Do not forget that we were back all our previous equipment, but we got a Thermaltake 500 watt power supply available, so we had already put in the machine that we thought that the stock of 300 watt power supply was a nameless, low power unit.   So far, he played several games at speed without any problems.   Our last thought is that the Pegatron m2n78 - the motherboard don't like prints of the power of the latest Nvidia cards.    I hope that helps you people!  Wooohoo! OK, it's game time!

• How to count the number of virtual machines on an ESXi server via command line

  I want to know the number of virtual machines running on ESXi. What is the command so that it...?

• All virtual machines running on ESXi 5.1 statement of Rx packet loss

  Can some of you please do me a favor? Find a virtual machine of yours running on ESXi 5.1, preferably 1117900 and let me know if you see a Rx packet loss in performance stats vCenter provides. Each single VM in my environment records packet loss. Virtual machines running on ESXi 5.0 are not related that at all. This also isn't a problem at the level of the host that there is no loss of package noted it.

  This is a known bug-

• 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.

• VCenter Server installed as a virtual machine within a ESXi servers it manages?

  Hi all.  I'm new in the world of VSphere... still in my evaluation period.

  I have only a single ESXi server running at the moment but plans to add a second later for high availability, vmotion, increase general capacity, etc.  They are / will be ESXi running on the internal storage and the virtual machines running on a shared SAN.

  Today, I installed VCenter Server 4 on a server at bottom of range/Office that I was carrying around running XP Pro x 64.

  As I was installing I read the guide installation and to my surprise, it seems to recommend that I have installed VCenter Server 4 as a virtual machine on my ESXi host.

  Now maybe I just spent too much time setting up my without new Lefthand requiring a 'witness' during the failover of one SAN to another... but I was under the impression that VCenter Server is not designed simply to host configuration, but is also designed to act as a 'witness' or to take account of quorum whenever a failure scenario occurred on one of my ESXi hosts.  I also noticed the VCenter Server features of a port "heartbeat", which I suppose one would use for the ESXi server heartbeat, but perhaps it is used for "connected mode" with other VCenter servers (I was intending to use only one since it is a small scale installation) I also felt that it would be useful enough to restore a damaged or shot ESXi host.

  So my question is, if my ESXi host dies and it is where I have VCenter Server installed, then high availability will be unable to work?  I guess there are going to be other issues with me unable to access VCenter Server while I have an ESXi host shot, too, as a greater difficulty to get the ESXi up?

  Maybe I'm wrong understand the purpose of the VCenter server... maybe it's not something that's necessary for HA, recovery, etc. and acts only as a configuration tool until something is wrong?  Or maybe I misunderstood the installation guide and they recommend only installing VCenter Server on an ESX box... they don't want this ESX box to be part of the group that manages the server?

  Finally, if indeed they recommend I install this on a ESXi host manages... would I ideally be install this for local storage on the server (where I installed ESXi) or on the SAN (where all my other virtual machines are installed)... or is it just personal preference?

  Thank you!!

  When you add hosts an active hemagglutinin vCenter cluster HA agent is installed on it.  This agent is what is actually the HA.  While necessary to add new hosts in a cluster and configure some specific parameters of vCenter vCenter's agents HA are self-sufficient and can handle HA failover so vCenter is offline.

  You must install the vCenter VM on SAN storage, so that he can use the vMotion, sVmotion, DRS, HA, functions etc. that require a SAN.

• 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.

• Migrate the Virtual Machine Linux to ESXi

  Hi all

  I have VMware Server 1 base on CentOS as operating system with a few VMs, VMS spot on my map of storage with NFS.

  I start converting those VMs with vmware converter 4.0 beta, I convert ESXi virtual machine move to storage even but with iSCSI.

  So far I have only converted machines Windows without problem, now, I try to convert the Linux (ContOS 5),

  After the conversion, I try to turn on the machine, but get a "Kernel Panic"

  Impossible to mount the SYSROOT.

  Please see attach.

  Until I find a solution I return to this virtual machine to the old vmware server 1 and then it works.

  Any idea?

  Thank you.

  Hello

  I don't speak of computer virtual SCSI controller, you can get to know that this process.

  (1) select the virtual machine.

  (2) right click go to properties.

  (3) select the Hardware tab, check for SCSI controller entry there you can see if it's the logic Lsi logic or bus controller.

  Once again something that I want to confirm, during the conversion, you had a SCSI disk for this virtual machine.

  Thank you

• Virtual MACHINE starts automatically after a power outage of the entire site?

  Hello

  We use ESXi 5.5.

  If there is a power for the datacenter failure, ESXi hosts must be restarted when power is resumed.

  We wonder if VMs will be launched automatically to the top?   If not, this means that we must allow the "starting the Virtual Machine / stop option.

  If we put a number of virtual machines in "automatically start", such as VM1, VM2, VM3 on ESXi Server one, VM4 VM5 ESXi Server b.   Virtual machines are migrated between ESXi servers and how they can keep the boot sequence?

  Your opinion is requested.

  Dear Tony,

  I ask you to create a vApp and configure accordingly on your vCenter boot order.

• All virtual machines to an ESXi Server ping

  Hi all

  For a project of mine, I need to create a script that asks for the ESXi server host name,

  and after that start ping all virtual machines that are on the ESXi server.

  I tried to do without success up to now.

  Help will be appreciated.

  Thank you!

  What follows is based on the fact that the VMware tools are installed.

  If they are not installed, you could adapt the script to try and ping displayname VM.

  $esxName = "MyEsx".

  Get-VMHost-name $esxName | Get - VM | %{

  $hostnamePresent = $_. Guest.HostName - don't $null

  {if ($hostnamePresent)}

  $pingable = test-Connection - ComputerName $_. Guest.HostName - count 1 - calm

  }

  else {}

  $pingable = $false

  }

  Select - InputObject $_ - the property name.

  @{N = "This Hostname"; E = {$hostnamePresent}},

  @{N = "responding"; E = {$pingable}}

  }

• Will be the virtual machine starts on another host (during the blackout) if he can't switch to Maintenance Mode?

  Hello

  We use a cluster with 2 5.1 ESXi hosts.  When attempting to place an ESXi host in Maintenance mode, he failed and said "not enough resources to satisfy configured level of failover for HA.

  We would like to know, just in case where one of these ESXi hosts failed, VMs will be start on another ESXi host (at least some) or all of them will be down (i.e. None of them start)?  If no virtual machine will be migrated, we will change our level of failover for HA.

  Thank you

  This occurs when you enable admission control on your HA cluster. When the failure of the host occurs and you have Admission control is enabled, it will let all market on the other host machines because it violates the constraints of availability.

  If you turn this off all VM is switched even if you do not have enough resources to accommodate all the s VM on a single host. On a long term, I would say that you have sufficient resources to allow this to happen. But for now, you can turn it off and try.
