Static pool: " Virtual Group Type " is " Linked Clone ", the desktop group will be randomly assigned to the user when the user logs in for the first time. A virtual machine is bound to the user, and a user can only be bound to one virtual machine

Proprietary types of desktop group types include " dynamic multi-user " and " single user "
