@Duncan Epping : the error cpuid.mwait appearing in log file.. which i assume this feature is already present in bios as these vLCS were working perfectly before storage vmotion. i have also attached log file.

I followed your article yellow-bricks , upgraded VMs compatibility from host console as this option was grayed out in vcenter, after disabling EVC, another vCLS vm was created but in poweroff mode, and the vCLS which was used to be created start working see below.
