identification of the virtual computer running on local storage
I am trying to identify virtual machines that are on local disks on specific esx hosts, but can't seem to find the right combination or references that map the. I'm ready to use all means available to help identifiening, console, vcli linux commands etc. Any help or pointers appriciated.
Thank you
Right now, I don't think there is a way to get the parameter of the BIOS with the SDK boot drive. The other question is do you want the diskette or the OS Disk/Partition? For the OS Partition/disk, you will need to query the GuestOS through VIX or any other interface and then that correlate with the SCSI Disk Device in your virtual inventory.
If you just need the boot drive, you can make the assumption that it is SCSI 0:0. It would change only by the intervention of the user manual via the BIOS of the virtual machine (F2 at startup). This assumption is not guaranteed, but it is likely be accurate, most of the time. I vaguely remember some talk around adding functionality to control the order of boot devices in BIOS of the virtual machine with automation. If it is added, it would be possible to detect and change the order of boot through a script or a program.
Something like the following would let you determine the location of the device node and vmdk file:
use strict;use warnings;use VMware::VIRuntime;OPTS::parse();OPTS::Validate();Util::Connect();My $vm_views = Vim::find_entity_views (view_type-online 'VirtualMachine',Properties-online ['name', 'config.hardware.device']);my $vm foreach (@{$vm_views}) {}My $vmname = $vm-> name;My $vm_devices = $vm-> {'config.hardware.device'};my $vm_disk foreach (grep $_-> isa ('VirtualDisk'), @{$vm_devices}) {}My $controller_key = eval {$vm_disk-> controllerKey};My $unit_number = eval {$vm_disk-> unitNumber};My $controller_bus_number = get_controller_bus_number (controller_key => $controller_key,)vm_devices-online $vm_devices);My $vm_disk_file_name = eval {$vm_disk-> support-> fileName};My $vm_disk_label = eval {$vm_disk->-> label deviceInfo};My $vm_device_node = sprintf ("SCSI (" %s: %s %s) ", $controller_bus_number,)")($unit_number, $vm_disk_label);printf ("%s: %s, %s\n", $vmname, $vm_device_node, $vm_disk_file_name);}}void get_controller_bus_number {}my (% args) = @_;My $controller_key = delete ($args {controller_key});My $vm_devices = delete ($args {vm_devices});my @controllers = grep $_-> key eq $controller_key, @{$vm_devices};# Must be only a controller since it is a key value in the VI SDKMy $bus_number = eval {$controllers [0]-> busNumber};Return $bus_number;}
Perl vm - scsinode.pl - username = administrator - server = 172.16.110.10Test: SCSI (0:0) hard drive 1, Test/Test.vmdk [datastore1]
Test: SCSI (1:0) hard drive 2, Test/Test_1.vmdk [datastore1]
In my output test, I would like to make the assumption that 1 the hard drive is the boot disk based on the SCSI Bus and the logical units (0:0). If you correlate this back at the sight of the GuestOS of disks, it would be the same values of Bus SCSI and logical unit.
You will notice that this basically recreates the same string that you would see in "Change settings" on a virtual machine by looking at its labels to disk through the user interface of vCenter.

Suppose that I'm leaving WinXP hostOS a guestOS. Then a part of this guestOS remain in physical memory and another part is deployed on hard drive in the swap file resp swap partition.
First question: the complete *.vmdk loaded into memory/swap space or only the part that is currently required?
Perhaps only a *.vmdk 800 MB / 3GB is really responsible. But these 800 MB could be extended to 2 GB, because the content of these 800 MB is not compressed during load or guestOS drivers allocate additional memory.
*. VMDK size seems so NO indicator for the actual amount of used memory / swap.
How will I know how much physical (a) memory and (b) the hard disk swap space EXACTLY is currently occupied by a certain virtual machine running?

The vmdk is not loaded into memory, because it is the drive of the virtual machine.
*. VMDK size seems so NO indicator for the actual amount of used memory / swap.
Yes, of course not. The memory used by the client is not related to the size of hard but the RAM assigned in the options of hardware reviews.
How will I know how much physical (a) memory and (b) the hard disk swap space EXACTLY is currently occupied by a certain virtual machine running?
Open the Task Manager and find a task vmware - vmx.exe or vmware-vmx - debug.exe.
The swap file should be used if you have chosen to allow that VMware Workstation is authorized to Exchange. The file where swaps to door expansion .vmem Workstation. Search folder of comments.

Can not power up the virtual computer after failure of storage
An error was received from the ESX host turning on VM myvm. Cannot create the file ' / vmfs/volumes/53309937-d077e300-a76c-0025b51a12ae/myvm/vmx-CDCSA1-805443817-1.vswp ': host no is not a newspaper could not start VMX: msg.vmk.status.VMK_NO_JOURNAL
Restart the ESX host solved the problems. Restart all services did not help. Air data warehouses / ReadOnly. VMotion would hang up on VM associated with these stores of data so that means a failure, forcing the host to restart.

Cannot modify memory and CPU of the parameters on a virtual computer running - vSphere 4
After a new installation of vSphere 4, I created several virtual machines and P2V had a couple as well. DRS and HA was set up, and everything worked well. If I understand correctly, I should be able to change the settings of RAM and the processor to a virtual computer running, but they are greyed out as with previous versions. I can change them if the virtual machine is shut down. No idea why this?
Thank you!
1 VM should be version 7 of material.
2. you must set the "Allow memory hot add" powered off mode.
Only after this, you can add memory to the virtual machine performance. Also, don't forget that Windows 2003 and 2008, Enterprise Edition and Datacenter Edition support this.

Hi all
For some reason, I have to disable and then enable the LAN connection in the host operating system. If some virtual machines are running during this time, connectivity all VMs for out-of-world are lost, they cannot connect to the host even more (by running the ping command). I tried a few methods to retrieve the connectivity, but all have failed, for example,
1. reboot the virtual computer
2. restart VMware Workstation
3. restart the corresponding system services in the host operating system
The only way I can retrieve all is to restart the host operating system itself.
Yes, is there short any path, I can retrieve the connectivity of these virtual machines?
Thanks in advance.

Try installing a newer driver. According to the site, you should be able to find a driver dated 2008 or 2007 (depending on which exact model of NetLink card you have):

Sometimes out of some firewall programs is not enough (they keep still themselves installed in the network of the host stack, even if they are 'closed'). You may need to uninstall to make sure that it is not interfere. (Search the forums for support for your firewall software see if anyone else is having problems with vmware and 360 safe guard).

need to reconfigure the virtual computer after deployment of the vm
Hi all
I have a script to deploy a computer virtual to a CSV file. I need to change the configuration of virtual machine (CPU and memory) after the deployment of the vm. where the name of the virtual machine should be taken to csv. So any help is appreciated.
Attach the script used. (downloaded and works fine)
$vms = import-CSV D:\vm-deploy\vm-deploy.csv
{foreach ($vm to $vms)
$Template = get-model $vm.template
$VMHost = get-VMHost $vm.host
$Datastore = get-data store $vm.datastore
$OSCustomization = get-OSCustomizationSpec $vm.customization
New-VM-name $vm.name - OSCustomizationSpec $OSCustomization - VMHost - $VMHost model $Template - $Datastore - Datastore RunAsync
}
# This cmd need to run after the vm deployment completed. The virtual computer name must come from the 1 column of the CSV file
Set-VM $vmname - NumCpu 2 - MemoryGB 5 - confirm: $false
Write-Host "All VMs deployed" - ForegroundColor Green
Disconnect-VIServer-confirm: $false
CSV file looks like this
Name, host datastore, Template, customizing
Test-VM,vm-dep-test,ESX02,P5-vm-stage,vm-deploy
Thanks in advance...
A simpler, but not optimal, solution is to use the Wait-job cmdlet.
Something like that
$vms = import-CSV D:\vm-deploy\vm-deploy.csv
$tasks = @)
{foreach ($vm to $vms)
$Template = get-model $vm.template
$VMHost = get-VMHost $vm.host
$Datastore = get-data store $vm.datastore
$OSCustomization = get-OSCustomizationSpec $vm.customization
$tasks += new-VM-name $vm.name - OSCustomizationSpec $OSCustomization - model $Template - VMHost $VMHost '
Data - $Datastore - RunAsync store
}
Waiting-task-task $tasks
{foreach ($vm to $vms)
$vm.name set-VM - NumCpu 2 - MemoryGB 5 - confirm: $false

Strange problem after moving from the virtual computer to a new data store
I am migrating our VM existing (8 in total) a 'problem' RAID to a new table on a new controller and am having a strange problem. Here are the steps I took (host OS is Ubuntu 8.0.4 LTS x 64):
(1) off the power the virtual computer from the Web interface
(2) the directories created for each virtual on the new RAID array computer (in this case a RAID 10 array on LSI 9750-8i controller)
(3) rSync used to copy the data from RAID1 to be RAID2
4) has created a new data store on the new RAID through the Web Server of VMWare user interface.
(5) removed VM of the inventory through the Web, their return, added user interface then choose files .vmx on new data store on RAID2
They have all power save fine... but three of them are not accessible on the network. I can open a console in the Web Server of VMWare user interface and they all run normally... but I can't their ping or access the respective virtual machine Web GUI. It seems quite arbitrary that those who work and those who are not. In this case... the VM that don't work is a license Autodesk, a Squid proxy server and a VM of cactus. All three of these virtual machines are 32-bit Ubuntu Server VM (two 8.0.4 and a 10.0.4)... and are the only Ubuntu VM on this host. It must be signifigant but I'm not see how.
If I delete these three virtual machines of the inventory again and add to their original location (on the RAID1) they light up AND work normally. A consultant that we were working seemed surprised, as he had also done this experiment with some of the older VMWare products. I don't see how it would be the physical location of the files of the virtual machine. Any ideas?
We rely on the migration to ESXi soon but in the meantime, we get these a few VM out of this RAID array problem. I'm stuck.
Depending on the application, it may be enough to reconfigure the IP parameters (they are very probably on DHCP now) for the newly detected virtual NIC.

Script to rename the virtual computer by name DNS listed in VC
I am very new to powershell, and I tried to understand this by using pieces of code I found, but nothing helped.
I'm looking for a script to take the given DNS host name for a virtual machine listed in VCenter and rename the virtual computer.
For example.
Host01VM01 (as shown in Vcenter) - the DNS name of the "something.xyz.com". VM and rename it "something.xyz.com" in Vcenter.
To run the script only for a group called "Mycluster" you can do:
Get-Cluster "My Cluster" | Get-VM | ` Where-Object { $_.Guest.HostName } | ` ForEach-Object { Set-VM -VM $_ -Name $_.Guest.HostName -Confirm:$false }
This script will only work for VMS that have installed VMware tools and probably only for VM which are turned on.

Get the IP address of the virtual computer? (when no DNS available)
I have a strange setup where I have a server vCenter runs in a private network that has no DNS available IN-HOUSE. I am running the scripts that query an IP address range, but takes forever to run. I can run get - vm and get all virtual machines, but can't do anything with them because there is no DNS and I can't find a way to enter the IP address of the virtual computer. If I could get the IP addresses I could then run functions against them. If it makes a difference those VMS have two network cards: Public and private. Any ideas?
The Get - VM cmdlet returns the IP addresses to the title of Guest.IPAddress count of the first IP address use as well:
Get-VM |Where {$_.PowerState -eq "PoweredOn" } |foreach { Write "$($_.Name) has an IPAddress of $($_.Guest.IPAddress[0])" }

Hello
In my VB.Net application, I retrieve the virtual computer object (VMware.Vim.VirtualMachine) through scripting Powershell VI.
If the Virtual Machine is migrated to another host (hotmigrate) I receive an event (VMware.Vim.VmMigratedEvent), which also holds the moref of the Virtual Machine. I tried to use the updateview method to refresh the virtual computer object but failed with an error message stating that the object could not be found, or never existed.
I also tried to recover the virtual computer object again, throug the method Client.GetView and the moref returned by the event, but the same error message.
How can I get my hands on the virtual computer object or update after migration to another host takes place. I have to get it back again? It would be great if I could do it somhow with information from moref I hold the event!
Any help is appreciated!

Sorry, but I can only show you how to do this in PowerShell.
I use the purpose of the task to get to the prompt MoRef.
Here's how:
$vmName =
$tgtHost = $tgtPool = $vm = Get-VM $vmName | Get-View $poolMoRef = (Get-ResourcePool $tgtPool | Get-View).MoRef $esxMoRef = (Get-VMHost $tgtHost | Get-View).MoRef $task= Get-View ($vm.MigrateVM_Task($poolMoRef, $esxMoRef, "lowPriority", "poweredOn")) while($task.Info.State -eq "running" -or $task.Info.State -eq "queuing"){ $task.UpdateViewData() } $vmImpl = Get-VIObjectByVIView -MORef $task.Info.Entity I don't know how you get at the VmMigratedEvent event, but the MoRef in there is pointing to the correct prompt.
In the following script, I extracted all the events related to the task of vMigrate immediately after the vMigrate task finished
function Print-VmName{ param($event) $MoRef = New-Object VMware.Vim.ManagedObjectReference $MoRef.Type = $event.vm.vm.type $MoRef.Value = $event.vm.vm.Value $vm = Get-View $MoRef Write-Host $vm.Name } $events = Get-VIEvent -Start (Get-Date).addminutes(-15) $events | % { $event = $_ $eventType = $_.GetType().Name switch ($eventType){ "VmMigratedEvent" { $eventType Print-VmName $event } "VmEmigratingEvent"{ $eventType Print-VmName $event } "VmBeingHotMigratedEvent" { $eventType Print-VmName $event } "TaskEvent" { $eventType Print-VmName $event } } }

Remove a hard drive from a virtual computer running
Hello everyone. Is there a way to remove a hard drive from a virtual computer running? Of course we can add a disk to a computer that is incredibly convenient, but there are times that we blow an as well. When clicked on the drive in the VI Client button is grayed out delete. I would have thought that other people would want to do that as well, but looking around the net and forums I find nothing!
Its not feasible in 3.5 and below.

Reload the Configuration of the virtual computer after changing the VMX file
Hello
If I make changes to a file on a virtual machine's .vmx in vCenter 5.5 is automatically valid configuration for the engine power vm off? I made some changes earlier and it seemed to be the case, but one of the steps that I see in some of the documents is to reload the configuration of the vm, so it can be used appropriately. So this happens automatically or not?
