• ESXI free Version host failure - how to recover virtual machines?

  Hi all

  I ran a VMWare lab at home with a free version of ESXI 4.1.

  My server does not and I have to reset all the settings management of ESXI and I lost my virtual machines.

  I solved the problem, but I lost the virtual machine.

  When I navigate through the data store I can see the virtual hard disk for my servers.

  Is there a way to recover these virtual machines?

  I guess that I'm not the first to ask this question, so if you could point me to any page with some instruction, it would be great.

  Thanks in advance,

  Fabio

  Welcome to the VMware forums communities.  In each folder of the virtual machine, you should see a VMX file for the virtual machine.  This is the configuration file.  Right-click on it and select Add to the inventory.  Then follow the instructions of the wizard and after the virtual machine market.  If your network configuration is the same as previously, then you should be good to go.

• How to access virtual machines after installing fresh windows?

  Hello

  I use windows xp & installed the virtual machines in the D drive to a folder. My windows crashed and I reinstalled windows fresh. Now please guide me how can I access my virtual machines? Already I again install vmware workstation 5. is it necessary to build my virtual machines again or there is another way if the already insatalled VM will connect?

  As long as you still have the files of virtual disk (hard) of the guest, you'll be fine.

  Open VMware Workstation and select to open an existing computer. Browser to the folder where the guest is stored. Select the .vmx file and guest must be back again.

  If you have only the left hard, create a new virtual machine (using the same type of SCSI adapter) when you are prompted to add a drive choose to add an existing one. Navigate to the hard and add it. Fact.

• How to recover a database after you add a data since the last file backup.

  How to recover a database after you add a data file to a tablspace existing since the last user managed backup.
  
  PS: I am aware that the user managed backups are not used and RMAN is used these days.

  At the stage of the mount: select name from v$ datafile;
  The last entry indicates a file named /xxx/xxx/.../UNNAMEDXXX.dbf

  Now

  ALTER database create datafile ' / xxx/xxx/.../UNNAMEDXXX.dbf' as 'path_where_you_want_to_add_the_datafile ';

  The name of the data file must match the name that added in production

  This will create a data file to the required location.

  Once the file has been created, you can continue with recovery.

• How to change the virtual machine after clone

  I'm a beginner to learn vm.

  Now, I already cloned a new existing virtual machine in a virtual machine.

  Then, I want to change it.

  (1) change the name

  (2) change the number of the processor

  (3) change the size of the memory

  (4) change the size of the disk

  How to do?

  I use c# API. I put something when clone?

  Thanks for any help!

  Hello

  You can clone the virtual computer to a model first and then deploy it to this model. For customizing the properties of guest operating system, you can use sysprep (from Microsoft) or customization Spesification Manager (from VMware vCenter Server). Of course, you can also configure it manually change settings menu (from vSphere Client).

• Network down frequently on a virtual machine after the upgrade of computers host and vmware to win 10

  Dear all,

  A week ago, I upgraded both my two machines VMWare Win 7 to win 10, as well as the host operating system. also from 7 to 10.

  Now once every 1 or 2 days, one or both the two vmwares aura an esclamation mark on the network status icon in the lower right corner and West no connection.

  The host operating system is NOT having any problems with the network.

  The solution is to disable and reactive the adapter to virtual machines, or repair of running Network Diagnostics where she'll tell me that it s has reinstated the connection to the bridge. But obviously I´d prefer the VM´s to be on the internet 24/7 without my intervention.

  I have another computer on the same router on which I did the same thing, but with this I m not having these problems. A different and not connected equipment via the VPN running on the host OS, which is the case with the machine that s had questions.

  But even once, the host operating system is not having issues, the two VM´s aren´t always the two to have this problem, and this never happened when he was all Win 7.

  I ve disabled some nights windows defender analysis and TCP/IP V6, but neither helped.

  Want to see some of the information from the last network diagnostics / repair or some log file, or you already know what would be the solution to my problem?

  Thanks in advance!

  Best regards

  Well, I thought that a vm was having this problem a lot more often than the other, so I looked for error messages in windows journal, showing that the network problem - have to with DHCP btw - always spent 2 minutes after an event regarding slui.exe, not found on the other machine.

  What I also noticed was that the problematic vm had lost its activation of windows with the upgrade to win 10 (win 10 has limits to how much the same license can be run as virtual machines), is is not the case for the more successful one.

  Then I copied the good machine, which contains the same as the other, changed mac and uuid and now it s showing that enabled, no problem so far.

• Unable to start the virtual machine after restoration

  Guests including Test host: ESXi 5.1.0.1065491

  Vm problem: 32-bit, Server 2003

  I use Veeam Backup & Restore 6.5 to back up my vm.  I always do a test restore to ensure that my backups are good.  I'm having a problem with a restore.  The 32-bit Server 2003 vm starts just fine on the main host it runs on.  All the vm are 64-bit except for one who is a 32-bit Server 2003 vm.  Restoring the machine virtual and implemented on a host except the 32-Bit vm Server 2003 test.  After restoration and trying power to the top, I get the following error:

  Unable to start the virtual machine.

  Turn on VPCM module has failed.

  Viewed performance counters require version 3 or greater of architectural performance monitoring.

  Anyone know if there is a fix for this problem?

  TIA,

  Mux

  I assume you are using different hardware (CPUs, the BIOS settings) for VMS restored!

  The virtual machine has VPCM enabled, which causes the problem. You can either disable it in vSphere Web Client (you can do this in the vSphere Client Windows), or directly modify the .vmx VM by setting vpmc.enable to "FALSE".

  For how toggle this setting in the Web Client see allow virtual in the Web Client vSphere CPU Performance counters. If you want to edit the .vmx file manually, you need to delete/re-add the VM from the inventory or recharge (see http://kb.vmware.com/kb/1026043)

• How to list virtual machines with associated vmdk files

  Hello.

  I have a folder vmfs and file vmdk with names that aren't like any virtual machine name (probably because that rename the virtual computer name).

  How can I find what VM is?

  Thank you

  Hello, biokovo-

  You can use the standard Get - VM and hard to find names of VMDK VMs-associated cmdlets Get-disc.  Or another, much more quickly elsewhere, would be to use everyone's favorite: Get-View.

  Since you know the path of the data store for the VMDK, you can check the property LayoutEx of virtual machines to find the virtual machine that said the file property with the name of the value as the games way to store data, as:

  $strVmdkDatastorePath = "[mydatastore] somefolder/somefile.vmdk"Get-View -ViewType VirtualMachine -Property Name,LayoutEx.File | ?{$_.LayoutEx.File | ?{$_.Name -eq $strVmdkDatastorePath}} | select name
  

  Where the path of the data store's format, "[datastoreName] folder/somefile.vmdk.  Yes, including the square brackets around the name of the data store and a space after the "]" (before the first character of the name of the folder).

  How does do for you?  (must be straight fast)

• Cannot depend on the virtual machine after reboot

  Hello world

  Thanks for reading this post.

  My version VM ESXI4.1.0, 348481.

  Here's my problem:

  One day my VM was hanged, and I tried to restart.

  After the reboot, it can be turn on. And I tried to remove the inventory and to recreate the virtual machine.

  However, I can't find the. VMX file in the data store.

  So I tried to create a new virtual machine and put the files in this folder, but it can also work.

  Please see the capture screen, (http://clip2net.com/s/2aNUG)

  Could someone give me guidance and advice how to solve?

  Thank you very much.

  According to the latest vmware.log file, you have tried to access one of the files base/flat with a wrong header file (40 GB)! This hopefully not bad data on the virtual disk. In any case, I've recreated the missing files (see attachment), so you should be able to redo the work of the virtual machine. Because the vmware.log file did not help, I've recreated the instant chain according to the timestamps of the delta file.

  Please follow it below mentioned steps exactly to avoid problems in case something does not work as expacted:

  • Make sure the flat files as well as files 2 6 delta are still in place (not renamed,...)
  • remove the virtual machine from the inventory of the host (right-click-> "Remove from inventory") ESXi
  • delete the temporary/second .vmx unless there is a special need for it
  • Download the files from the .zip file in the folder of the virtual machine on the data store
  • Click right newly downloaded virtual machine's .vmx file and choose "add to the inventory.
  • create a new snapshot (this is important!)
  • Turn on the virtual machine

  If something is not or you have questions, please send back before moving on to the other steps.

  If everything works as expected you should consider the 'Delete All' snapshots in snapshot Manager. This will release not only almost 200 GB of disk space, but can also improve the performance of the virtual machine. Because the size of the snapshot, remove snapshots may take some time, probably in hours!)

• Error occurred by restarting the virtual machine after instant collection

  Configuration:

  2 X ESX 3.5 U3 in cluster (Enterprise license) + Virtual Center 2.5 update 3

  18 customers running Win2k3 servers and Oracle on RHEL 3 servers

  2 X SAN DELL MD3000i with two controllers (active / active).

  Question: Last night, when the backup of VCB, we lost the SAN n ° 1 completely (two controllers at the same time).

  We have a few customers with Microsoft Raid 1 (1 on San 1 and 1 drive on San 2).  guests in mirror mode survived 40 minutes after the San n ° 1 crashed.

  After checking saves files I found that: ESX shutdowned guests due to a problem with the snapshot.

  I feel really bad this morning... because I told my boss we're safe if we lose 1 SAN because we are mirrored on 2 SAN.

  Why stop ESX invited after problems with snapshots. Also, we received a lot of Virtual Center with false alert alarms (virtual machine does not).

  ESX filled 800 megs of log files in a few minutes with the same message (path fails, try another a blabla).

  What the purpose of putting my guests in mirror mode stop ESX if my guests after losing the path during backup?

  Hello

  Conclusion?

  If SAN #1 accident during the VCB backup, you're dead?

  If you use software raid within the virtual machine is then SAN1 dies, the VM will crash because the Bank of support file (this case a delta) is no longer available and there is no way to read or write data even.

  Software RAID does not apply to things outside of the virtual machine. A solution would be to have a device that can do Raid through mirroring without.

• Cannot start the virtual machine after you create snapshop

  I found a strange behaviour. I have a Windows 2008 guest that I just copied in my new box ESXi. I am trying to create a snapshot before upgrading the guest to 2012 Windows operating system. The virtual machine has currently no snapshots. Whenever I have create a snapshot, he succeeds, but then I can't start the virtual machine saying that it does not find the vmdk file delta even though I see there in the data store. In order to start the virtual machine, I have to delete the inventory and it readd, but then I lose the snapshot. I also have another computer virtual running Windows 8.1 that does exactly the same thing. How can I create snapshots safely without damaging the virtual machine? I also tried to create the snapshot while the virtual machine has been activated but that makes crashing and then it does not start again, so I have to repeat the process to remove the inventory and it time. Frustrating. See the screenshots, I have attached.

  Once these virtual machines have been in Hyper-V in the past and I just convert to VMware format using the StarWind V2V converter.

  Yes, for an ESXi host and target you must either select the ESX f.vmdk as format target (growable option is for VMware Workstation), or you must convert the virtual machine once more instead of simply upload the files to an ESXi host.

• What is the best way to restore virtual machines after a refresh of the server

  Hi all

  First time poster here. A group of people at my work have their own VMWare environment which they install later. It has 3 virtual machines running on it, and they want to set up a fourth. Unfortunately the new machine, they want to put in place is going to be almost 1 TB in size, and they initially setup the VMFS datastore to 1 MB, which means that a machine can be as large as 256GB.

  Research, it seems that there is absolutely no way to work around this problem, except to redo the data store. Is this correct? If this is the case, I was looking at a way to save the three current machines and to reload them after it is updated. A way that I thought was to go browse the data store and copy all the files on my local machine to the virtual machine (.nvram, hard, .vmx etx... all the files), wipeout and redo the ESXi host with the correct setting of data store, build the machines VMS in vSphere, and then replace the files with those copied. This works perfectly? I don't see a lot of information out there about it and I want to make sure that I have not to spoil the VMs. This environment consists of 1 ESXi host with all the local storage (2 TB).

  Also, if anyone knows a better way to do this, please feel free to give your comments. I would really appreciate it.

  Thank you

  Yes, unfortunately there no way to change the block size of the datastore to vmfs without reformatting.

  Yes, it will work. You have just to copy all files in this VMFS datastore to a place safe and download once the block size has increased. Once the download is complete, navigate to the virtual machine, the virtual machine folder right click and save the VMX.

  You can find the steps to change the size of the block VMFS in this KB. VMware KB: block the size of a VMFS data store limitations

• List not updated virtual machines after the migration of the virtual machine to a different data store

  My vSphere infrastructure 5 uses several data stores.

  Two data warehouses are associated with NFS on different NAS shares.

  I migrate VM to a data to another store.

  The navigation data store, I see that the files are moved from the old data store to the new and that no file belonging to the migrated VM still does exist on the old data store.

  If I look at the list of VMs on the old data store, I still see the old VM.

  I see it in the list of the virtual machine on the new data store as well.

  I checked that no .iso no pagefile is in the old data store.

  How can I update the list of the virtual machine on the old data store?

  Above all, how can I safely delete the old data store by ensuring that the virtual machine works very well on the new data store and I don't lose anything?

  Concerning

  Marius

  This use of data store 'Phantom' is usually observed, if the current configuration of the virtual computer points to the 'old' data store (diskette, CD-ROM) or the virtual machine contains snapshots where - at the time where tone have been created - the VM has had these references. Once the snapshots are deleted from data store 'ghost' will go away from summary of the virtual machine.
