How CLoning Process works in the background???

Dear VMware Experts,

I want to know " How CLoning Process works in the background???" , as per my understanding is it work like this

1) Snapshot a Cloned VM

2) Registering a VM to a destination host

3)Copy the .vmdk files to a destination host

4)commit the snapshot disk to the destination host (changed blocks r commited)

Can sum1 brief the cloning process.....

Regards

Mr VMware

Almost correct, step 4 the snapshot disk gets committed to the source VM not to the destination VM, with a vCenter hot-clone no changes after the clone operation is started (i.e. the snapshot is added to the source VM) will be written to the destination VM.

If you use VMware Converter it has a "synchronization" option that you can check so that it does a multiple passes to pick up any changes that happended during the clone operation.

One more thing to remember is that hot-clones are crash consistant so there is the possibilty to lose some data, although in my experience it's never been a problem.

regarding this : (i.e. the snapshot is added to the source VM) will be written to the destination VM.

you mean it will NOT be written to the destination VM, correct?

ok, it's getting complicated here with you double negativity here (almost like in strange multiple choice questions  Smiley Happy)

"no changes .... will be written to the destination VM" is correct.

which means at the same time that "it will NOT be written to the destination VM"

//otherwise it would be "no changes ... will not be written to the destination VM" which would mean the changes will be written....:-)

Ah lol, I understand now, it was just becuase you put the 'no' long way before, and for a non native english speaker it will be hard to understand,, hader than understanding cloning and snapshots :smileygrin:

Things are clear now for me,

Thanks , Cheers.
