Linux VM Sizing

Howdy,

We are sizing a Linux VM to migrate our Oracle production database to.  We are currently running on an Oracle Database Appliance.  Oracle CPU / memory usage stats are:

CPU % usage - 25% of 20 cores / 40 threads (Intel® Xeon® S4314 processor)

Memory % usage - 100% usage of 600G SGA

Based on the above can anyone give advice as to how to size the CPU / memory of the Linux VM, please?

Thanks,

Sam
