We receive a request from a new customer for a z/Linux guest on a BC12. The
specification that the vendor supplied is for an intel platform. Does anyone
know is there a formula to convert intel cpu cores to IFL?

We've had several incidents where one Linux server has high CPU utilization and
impacts other servers from other applications. We were asked to prevent this
