• Question about snapshots and virtual machines

  Hi all

  I have a small question about snapshots. I use VMware for about 6 months and I read about snapshots and how they work but still have a question to make sure that I understand how it works and it will work the way I think it works.

  I have a Windows 2003 server, which is a virtual machine. I have an application that uses MSDE database. I want to upgrade the database to MS SQL 2005, but to do this I need to back up the MSDE database, uninstall MSDE, and then install SQL 2005 and move the SQL database. This happens on the same VM.

  What I was thinking if I well Snapshots correctly is to snap turned the virtual machine before doing anything. Then do my upgrade steps and see if everything works. If its all messed up so I should be able to return to my shot and everything should be the way he had. What is the good? One of the main reasons I moved the server VM was because of this upgrade.

  After reading the documentation for the snapshots, it's how I undestood it. Pretty much any change could be reversed with snapshots. I wish just they had put in a few examples in the PDF file. Also it would be the same for all type of grades of the OS? Could I snapshot a Windows 2000 Server, and then "in the upgrade of the square" to Windows 2003? I've cloned a VM to do this but was curious about whether snapshots would be just as easy.

  Thanks for your help.

  That is right.

  Exactly the same thing for the upgrades of the OS.

  Perhaps the most important thing with the snapshots is to keep an eye on them and don't let them sit too long or become too big.  You have described the use cases are very good uses for snapshots.  Just make sure you have a solid plan with a schedule set, so that you can come back or validate changes before the snapshot becomes too large.

  Good luck!

• deploy multiple virtual machines using vmdk and SID file

  Hello

  Need to know if I am correct or miss me something... I deploy many virtual machines using method.

  1. remove the vmdk files a XP.

  2. create new folders and copy the vmdk into this folder.

  3. create virtual machines using existing vmdk files.

  4 rename the computer and join it to the domain.

  My question is, my VMDK files are an existing xp VM (no longer exist), what is the status of the deployed virtual machines? they still have the same SID or it is changed? I managed to join to the domain, but do not want surprises in the future.

  Note:

  I had another option, could have all these automated with new SID using PowerCLi, unfortunately, osCustomization has default, I can't event run the get-OsCustomization command, it keeps failing.

  Thank you.

  Yes, Windows writes the SID on disk (virtual disk for virtual machines) or physical disk for physical machines.  The guest operating system has no idea on the vmx file.

• Syntax to create a new virtual machine using vCLI

  I use few of ESX 3.5 servers and a server vCenter 2.5 in my lab. I installed vCLI in vCenter server. I would like to know the command to create a new virtual machine through the vCLI. Use of the below details to provide the syntax / command.

  • Name of VM - windows2003
  • CPU - 2
  • Memory - 2096 MB
  • Name of ESX - esxserver1
  • Storage - disk 30 GB C and 40 GB D drive (these two must be placed in a storage centralized. i.e., data store name is - "filer1.lun123"

  Expecting more details.

  Thank you

  VCLI orders are mainly used for configurations of the host, although as part of the installation of vCLI, you get also vSphere SDK for utilities Perl - http://www.vmware.com/support/developer/viperltoolkit/viperl41/doc/vsperl_util_index.html that provide additional canned scripts, which allows you to create a single set of virtual machines using the vmcreate.pl script. There is an example on how to use a script

• Virtual MACHINE using GHS restore CD

  I'm new to VMware and I'm trying to implement a virtual machine using XP Home.  I created the virtual machine and I am trying to use the restaurant 3 CD to install the operating system.  The first CD works fine, but the second can not open the file .ghs.  When I try to open the .ghs file it shows same not she, but a .gho file is there, but does not work.

  Any suggestions?   I need to convert a .iso?  If so, how?

  Thank you.

  Theoretically, you can't use restore CD to configure a new virtual machine, because they are technically linked to the computer to which they belong.

  Because the virtual hardware for a virtual machine is completely different with the material belonging to the restore CD, I don't expect that it will work well. For the case, it works well, you could face activation problems, due to the completely different (virtual) hardware.

  You might need a copy of XP retail to do a clean install of XP.

• 890124. how to move a virtual machine from one storage to another?

  Hello

  I decided to increase the RAM of a virtual machine and storage space in which stood the machine is less than 1 GB, it says that it is impossible to start the virtual machine. So I decided to move the virtual machine to secondary storage which had enough free space.

  How can I make vSphere Client aware of this change? How can I know what's happened? what I need is to boot the machine which is now moved to secondary storage. is this possible?

  THX

  After again moving data store, you must register this virtual machine to be visible in the list at left.

  1 browse the data store and open the corresponding VM folder

  2. Select the .vmx file and right-click.

  3. Select the option "Add to the inventory" and keep clicking Next until you have finished.

  4. now switch on the machine. He will ask a question that you copied or moved.

  5. Select I moved it.

  6. your machine is running.

  And you can see the virtual machine in the list after step 3 itself.

• Some questions about replication

  Hello

  I have several questions with vSphere replication.

  -Can I replicate a server ESXi isolated VM, without vCenter?

  -If I can, you could turn on the VM as if necessary? because when I turn on the virtual machine, I manage in vcenter console

  -If I reproduce it in vCloud, how should I? I need to download a camera in my office and the other in my cloud?

  Thanks for help

  Hello

  -Can I replicate a server ESXi isolated VM, without vCenter?

  You have vCenter Server to replicate virtual machines inside or between data centers. VR as a product is installed on vCenter level and is only available if you are using vSphere Web Client connected to the server vCenter.

  -If I can, you could turn on the VM as if necessary? because when I turn on the virtual machine, I manage in vcenter console

  vSphere replication is not disrupt the work of the virtual machine. It monitors which changes the VM and the changes are replicated

  -If I reproduce it in vCloud, how should I? I need to download a camera in my office and the other in my cloud?

  If you build your own private cloud using vCloud Director VR allows to respond directly to the vCD, as VR currently supports only VC as target. You can however check VMware vCloud hybrid Service: overview | United States if you want to replicate in VMware vCloud hybrid service, workloads

  Hope this helps

• Someone at - it a simple example of creating virtual machine-> the affinities of virtual machine using the PERL API?

  The question just about everything said. Is there a perl extracts to create an affinity between the virtual machines.

  Thanks, Vikas, for example and guidance. Since I am abel to make it work, I thought I'd share the code example:

  My $vm_name_list;    # A list of names of virtual machine.

  My @vm_morefs;      # Filled in the managed object refes to the virtual machines, this detail not included.

  My $cluster_name;    # Name of the cluster to create the rule in

  # Find the Cluster Compute resource object.

  My $cluster_views = Vim::find_entity_views (view_type-online 'ClusterComputeResource',
  filter-online {name-online $cluster_name});
  If (! @$cluster_views) {}
  Die "no cluster don't compute resource named $cluster_name detecte\n";
  }

  My $cluster_view = $cluster_views-> [0];

  My $rule_name = 'affinity for $vm_name_list. "

  # Create the nest of objects required for ReconfigureCluster_Task:
  #
  # ClusterConfigSpec
  rulesSpec #-> [ClusterRuleSpec]
  operation #-> ArrayUpdateInformation
  # enum (add, modify, delete)
  Info #-> ClusterAffinityRuleSpec

  My $aff_rule_spec = new ClusterAffinityRuleSpec (name => $rule_name,)
  enabled-online "TRUE."
  mandatory-online "TRUE."
  VM-online \@vm_morefs);

  My $array_update_operation = new ArrayUpdateOperation ("add");

  My $clus_rule_spec = new ClusterRuleSpec (operation => $array_update_operation, info-online $aff_rule_spec).

  My @clus_rule_specs;
  Push (@clus_rule_specs, $clus_rule_spec);

  My $cluster_config_spec = new ClusterConfigSpec (rulesSpec-online \@clus_rule_specs);
  $cluster_view-> ReconfigureCluster_Task (spec => $cluster_config_spec,)

  change-online 'TRUE'));

• Create a virtual machine using an existing backup [EXSi 5.0.0]

  Hello

  I've looked everywhere to find a thread that explains me to reach higher. Our ESXi is currently a backup copy using ghettoVCB and store it on an external NAS. I know that I can simply restore a backup virtual computer by using the same script, because it supports.

  But what I want to achieve is to create a separate entrance to the virtual machine by using an existing backup. I'm pretty there is a way, but I now know how to because I'm fairly new to ESXi and learn things slowly.

  All advise you will be highly appreciated and thank you in advance.

  Hello

  I finally managed to do that. I should tried before posting this discussion, but somehow he's ready now. Back to ESXi users who are finding similar questions or have a confusion on how to achieve this, you can see below the process and this;

  1. Before you copy, make sure that you have appropriate files related to the virtual machine (there should be a .vmx, hard & sometimes flat hard-000)
  2. Copy the folder to the location of data store where is your VM (generally, it will be under/vmfs/volumes/yourdatastore) using ssh and WinSCP (a tool to connect in ftp/sftp/scp).
  3. Once copied into the data store, go to the data store by visiting configuration > store > select the data store & access your virtual machine directory, then simply add the .vmx file to the inventory by clicking on the right (Note: do this when you are connected to the ESXi using vCenter IP which is the recommended way to do).

  I hope this helps!

• Question on networks of Virtual Machine

  I have a host machine running Windows 7. I installed VMware player and I create a virtual computer running Oracle Enterprise Linux 5.5 (almost identical to the version 5.5 of Red Hat). In the end I will be installing an application on the virtual machine that is not compatible with DHCP. So, when I install OEL 5.5 I need to manually provide information from network devices (IP address, primary DNS, subnet mask and host name). I've done it before on successfully on a material physical but never before on a virtual machine. On my first attempt I was wrong and my web browser running on the virtual machine can connect to the Internet.

  My instructions say "set the gateway information based on the IP Address of the gateway router. I wonder if this is correct in view of the virtual machine.

  On the machine host, when I run the ipconfig command in the DOS window I see a mask of address and the IP subnet for the host, and I see two additional network adapters for VMware (VMnet1 and VMnet8). The three entries (for example, the host VMnet1 and VMnet8) have the same subnet mask value and different IP addresses (first two segments of the IP addresses are the same, third and fourth segments are different).

  My question is, what are VMWare network cards and I have to pay attention to these IP addresses when I manually configure networking on the virtual machine?

  VMware Player provides essentially 3 types of network connections:

  • 'The bridge' - directly connected to your router
  • "Host-Only' (VMnet1) - limited to the host and the virtual machines network
  • "NAT" (VMnet8) - network address translation

  VMnet1 and VMnet8 virtual cards that allow the host to communicate with the virtual machines and vice versa.

  Depending on if your virtual machine should be accessible from other systems, you can consider using (in - and outgoing) Bridged or NAT (outgoing mail). With Bridged networking, addresses are usually provided by your router/DHCP server. For NAT, the address of the gateway/DNS is 192.168.x.2. Since the VMware Server DHCP internal for NAT and Host-Only uses 192.168.x.128... 254 for dynamic addressing, you want to select a static address in the 192.168.x.3... range 127.

  The easiest way to find out how to correctly configure the network, must first set the operating system to DHCP, note gatherings settings and then just choose another IP address when you configure static settings.

• How to add a script to a virtual machine using vmwrae api?

  Hello

  I am trying to add a new disk to an existing VM (Linux).

  To do this.

  
  

  Now to use the new drive on a run a series of commands, like:

  -format the drive

  -mount the drive

  -put this information to disk in the file/etc/fstab

  
  

  My question is how we can automate this task without actually going inside the virtual machine?
  

  This is precisely what my advice is intended to accomplish. There are many examples available online to use Invoke-VMScript to automate actions in a Linux VM.

  http://www.Google.com/search?q=invoke-vmscript+examples

  This was done from my Windows using PowerCLI workstation to a virtual machine running SLES:

  PowerCLI C:\> Invoke-VMScript -vm $vm -HostCredential $hc -GuestCredential $gc -ScriptText "uptime"
  
  ScriptOutput

• Virtual machines use a data store file?

  I think I have a couple of orphaned files hard in one of my data stores, but I hesitate to delete it without confirming that it has been adandonded. I know that I can use the menu change the settings to manually search on each virtual machine if the file in question is in use, but is there an easier way to determine this on the opposite side?

  I would like to be able to tell what VM a special hard (or any file in the data also store) is linked to.

  Thank you

  You can use something like RVTools to check your inventory

• Conversion to a virtual machine using VMware Player?

  We have an environment consisting of ESX:

  • vCenter 4.0.0 (build 162856)

  • Runing host ESX 3.5.0 (build 163429)

  I have very limited exposure to VMware Player and who has been with the first versions.

  We received a request to make an existing virtual machine in Windows 2008 for use with VMware Player.

  1. Is this feasible?

  2. I had user Converter?

  3. I'm confused about the end result and how to deal with operating system licenses and IP information as they proliferate this image in VMplayer?

  Looking for some tips and information to help me get started.

  I usually copy the complete directory of the virtual machine on ESX to a host with vmplayer and it - just run without any conversion. Just doubleclick vmx-file...

  This works even when the virtual machine has snapshots, although I do not recommend.

  If I have problems they can usually be cured by a simple modification vmx and vmdk so I amy forget a step here.

  Anyway - just try and come back with error messages.
