Hi

I have created a linux red hat Virtual machine on top of Vmware Esxi.. The problem is I discovered that the VM Virtual hard disk is thick data provisioning.. is there a way to change it to think without rebuilding the disk or reinstalling everything from sratch?

Not sure if you can run vmkfstools in "unsupported" mode(for esxi)
but vmkfstools can copy a thick disk to a thin disk
Use the standard vmkfstools clone/export parameter (-i) while specifying "thin" for the target disk format

How I can run the vmkfstools tool? I tried to telnet and ssh my vmware server, but I could not access (Connection refused)

Thanks, but two issues here:
1- the VMWare VCenter convertor does not support vmware 7
2-  It is only work with Infrastructure platform and not ESXi platform.

As for enabling the SSH, when I press alt+F1, nothing happens!

If you have downloaded the latest VM Converter (v4.0.1) it should support VM Hardware version 7?

Commented:
And it does support ESXi 4. I just tried.....

The last thing in the drop down menu of the convertor is 6.5.x.

Now I was able to convert the VM and save it to local drive.. How I can now import back to the VMWARE server under the vSphere?

If you had enough space on your ESXi datastore you could have just V2V'ed directly there into a new folder.. :-)
But since you've already have it on your local machine. You can use Veeams FASTSCP (www.veeam.com) to move it from your local drive to your ESXi Server ... FASTSCP is a great tool especially since it is FREE! :D

Excellent tool... I moved the copy using FASTSCP to the VMWARE SERVeR under a new directory.... Now, how I can configure the vmware server to see the new copy and to run it?
za_mkhIT Manager

Commented:
Using the vSphere Client, on the configuration tab, click on Storage and then right-click your datastore and choose browse.
Open the folder that has your VM. Right click on the VMX file and choose "Add to Inventory"

just connect to esxi, browse datastores, select the folder for the vm, find the vmx file, right click and add to inventory.

When I do that I got the following error message when trying to startup the VM

Faild to open Disk scsi0:0: Unsupported and/or invalid disk type 7. Did you forget to import the disk first? Unable to create virutal SCSI device for scsi0:0, /vmfs/volumes/4a505033-0642d78c-5bf1-00215e64d528/informatica011/informatica011.vmdk' module devicepoweron Power On Failed.

What does that mean? how I can fix it?

I solved the issue by SSH the VMWARE server, then use vmfkstools -i -d thin, it clone the virtual hard disk, and created a new one that is compatible with the current version.. Thank you all.
The command is vmkfstools
