You have a point +1 But i am confused where i didn't tell undercloud what kind of VM i am going to use for overcloud then how does undercloud find out i am using 2 vCPU and 2GB memory vm? On VMware i don't have any ipmitool etc where undercloud inspect my hardware.
That is what i am trying to understand how undercloud going to inspect my hardware in VMware Workstation?
