Hi,

Can you try to take a snapshot without using "Quiesce guest" mode.

Otherwise, you can check here. http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=101819...

Try the below steps

1. Uninstall VMware Tools.
2. Allow the system to reboot.
3. Reinstall VMware Tools. Ensure that you click Custom Install.
4. Deselect VSS

and for more info follow as mentioned in the KB VMware KB: Cannot create a quiesced snapshot because the snapshot operation exceeded the time limit ...

To work around this issue in earlier builds of ESX/ESXi, use one of these options:

• Allow VSS application quiescing to work by generating Disk UUID/Serial number. This can be achieved by leaving the disk.enableUUID value to true and power cycle of the virtual machine.
• Disable VSS application quiescing feature by setting one of these options.
  
  Note: This is a non-disruptive process and does not require Virtual machine downtime.
   
  • Disable application quiescing by disabling the option from VMware Tools.
     
    1. In the Windows guest, create the file  %SystemDrive%\ProgramData\VMware\VMware Tools\tools.conf.
    2. Add these entries to the tools.conf file:
       
       [vmbackup]
       vss.disableAppQuiescing = true
       
    3. Restart the VMware Tools Service.
       
       
  • Change the value of the disk.enableUUID parameter from true to false by modifying the virtual machine's configuration file (vmname.vmx) and migrate the virtual machine to another host in the environment to reload the virtual machine configuration into the host memory.

Ok , and if you uncheck this option ?  The snapshot is ok?

Because if you did this

               "  I had uninstall VMware tools and reinstall tools excluding VSS, still we are facing same error.."

                              You cannot create a snapshot using this option.

Julien.

[srikanthraavi]

Yes, You are right Julien.
