Understanding Resource Values
The!values!under!Resources!indicate!a!range!of!percentages!of!a!processor!to!which!the!
virtual!machine!is!entitled.!Resource!information!displayed!includes:
! Minimum!–!Minimum!amount!of!processor!capacity!that!must!be!available!to!
power!on!the!virtual!machine.
! Maximum!–!Highest!amount!of!processor!capacity!the!virtual!machine!can!ever!
consume,!even!if!the!processor!is!idle.!The!maximum!value!can!be!larger!than!100%!
if!the!virtual!machine!has!more!than!one!virtual!CPU.
! Shares!–!A!relative!metric!for!allocating!processor!capacity.!The!values!low, !
normal,!and!high!are!compared!to!the!sum!of!all!shares!of!all!virtual!machines!on!
the!server!and!the!service!console.!Share!allocation!symbolic!values!can!be!used!to!
configure!their!conversion!into!numeric!values.

! Isolated!from!Hyper‐Threading!–!CPU!operation!state!of!the!virtual!machine.!
Enabling!this!option!prevents!a!virtual!machine!from!sharing!a!physical!CPU!with!
other!virtual!machines!when!Hyper‐Threading!is!enabled.
