Hello,
I am searching for the proper API to find the absolute path to a Virtual Machines vmdk file.
Let’s say inputting the minimum amount of information (ideally just the Virtual machines
name) i would want to get the path like this:
"[ [storage1 ]] MailServer/SystemDisk.vmdk"
Can anyone point me to the right api or if they even know the methods/procedures that would be even better.
thank you
You might want to refer to the C# sample GetVMFiles.cs that is shipped with the vSphere SDK package. The sample accepts VM name and the path to store the VM files ( .vmdk, .vmx etc) as input arguements and downloads all the VM files to the path specified. Based on your requirement, you can filter out only the vmdk files. This sample makes use of Http files access mechanism to download the VM's files.
The command to run the above sample is: --url https://<server IP> --username <username> --password <password> --vmname <virtual machine name> --localpath <path where to store the files
I am looking at that right now thank you Angela.
Is it possible to find all of the virtual machines that are managed by a vsphere machine or an ESX server. ie get all the virtual machines names <currently residing on an ESX server. Or one better get all the virtual machines names that the Vsphere is managing on its ESX servers?
It might be easier to query by the VM's display name since VMware allows you to have a different display name than what the actual files are named, at least you can match what you're seeing using the vSphere client.
Here is a script using vSphere SDK for Perl getVMDiskInfo.pl that lists all VMs and their full path to their disks, you can modify it to display what you need but an example to get you going.

I am not very fluent in perl however without learning perl i want to say this line
$vm_view = Vim::find_entity_views(view_type => 'VirtualMachine');
is a key [art to finding all vms by their name.
i am assuming you dont use the same API reference as the Java and C#
would you say this method FindAllByDnsName
is similar to what you are using, or might be the answer to my solution?
FindAllByDnsName
"Finds all virtual machines or hosts by DNS name. The DNS name for a virtual machine is the one returned from VMware tools, hostName."
I think it is unless this name could be different then the name of the vmdk in which the machine resides on.

I think I should have said my intentions. I need the path to the VMDK to use in the vddk api. what i am trying to do is get the path for the vmdk in order to use it in with the vddk.
i believe the way they are doing it is with this line
vmDir[0] = vmConfigInfo.files.vmPathName;
where they have the stored path name
vmConfigInfo.files.vmPathName will give the path of VMX file but not the VMDK disk path.
For getting VMDK disk paths,
1. Get all virtual devices for a given VM...
2. Filter out the Virtual devices that are Virtual disks.
3. virtualdevice.backing.filename is the required VMDK disk path.
vmConfigInfo.hardware.device will give all the devices.
Filter them wrt properties VirtualDeviceFileBackingInfo or __VirtualDiskFlatVer2BackingInfo etc
virtualdevice.backing.filename will give the VMDK disk path
ManagedObjectReference vmMor = getDecendentMoRef(null,"VirtualMachine",vmname);
example: VirtualDevice vDevs = (VirtualDevice[])getDynamicProperty(vmMor, "config.hardware.device");
vDevs[i].getBacking().getClass().getCanonicalName().indexOf
("VirtualDiskFlatVer1BackingInfo")
{
//if (vdevice.backing != null && vdevice.backing is VirtualDeviceFileBackingInfo)
if ((vDevs[i].getBacking() != null)
&& (
(vDevs[i].getBacking().getClass().getCanonicalName().indexOf
("VirtualDiskFlatVer1BackingInfo") != -1) ||
(vDevs[i].getBacking().getClass().getCanonicalName().indexOf
("VirtualDiskFlatVer2BackingInfo")!= -1) ||
(vDevs[i].getBacking().getClass().getCanonicalName().indexOf
("VirtualDiskSparseVer1BackingInfo")!= -1) ||
(vDevs[i].getBacking().getClass().getCanonicalName().indexOf
("VirtualDiskSparseVer2BackingInfo")!= -1)
))
{
VirtualDeviceFileBackingInfo vBackInfo = (VirtualDeviceFileBackingInfo)vDevs[i].getBacking();
vmDiskURLs.add(vBackInfo.getFileName());
}
}
I downloaded the SDK and tried building GetVMFiles.cs. However when I run it on the guest (Windows 2003 Server) on vSphere 4 it just crashes. Do I need any specific runtimes or other packages to be installed on the guest? Thanks.
