The VM CPU reservation of 4340 Mhz is preventing the power on.
Have a look at the current amount of unreserved CPU for the immediate parent object of the VM, and if that parent object has an expandable reservation you should do the same for the grandparent object (and so on). The number of CPUs of the VM could also be a factor, the reserved virtual resource needs to be physically possible.
There are numerous potential root causes as to why you get this error, but insufficient information here.
