It still doesn't work when I delete the row "sched.swap.derivedName".
A consultant asks me to add the following row workingDir="/vmfs/volumes/50cebaea-280302cd-8274-0026b9612b6d/FINANCEVM" and it works. I don't know whether it swap file will reside at the root of datastore again.
Is there any suggestion why it happens ?
Thanks
