Public bug reported:

VM goes to error state in ESX while resizing due to Insufficient disk
space on datastore.

Ideal behaviour should bring the Instance back to Active state.

Resize try to clone VM, if datacenter has no free space for that flavor
size then it will give error "Insufficient disk space on datastore".

Exception move VM to error state.
