Sorry about the delay. You cannot take a quiesce snapshot without tools installed and running. The process is as follows:
You initiate a quiesce snapshot
->vCenter / ESXi host contacts the hardware virtual chip on the OS that communicates with VMware tools
->VMware tools picks up this command and tells the OS to flush buffers in prep for a stun
->Stun happens and snap is made
->Life goes on
If quiesce fails it still does a crash inconsistent snapshot. If you are using Windows the method for quiescing is VSS so check your event logs of VSS events... if you have no tools you should not see anything.
I could be wrong but that is my understanding. What evidence do you have that it was a quiesced snapshot vs a crash inconsistent snap? I would like to play with this more ...:)
Hi Gortee, Joseph
Thanks for replying. I was looking for a online screen recorder so I could share the video with you.
I created a new VM and installed Windows 7 on it. I did not install VM tools and then tried a quiesce snapshot. I clicked on take snapshot -- unchecked memory --- checked quiesce and the snapshot completed fine.
If possible can you please try it in your lab.
