Victor, it is the accumulation of ALL the IFL utilization and the LPAR
weights. The other LPAR is able to use any of the 4 IFLs, but only 3 at
a time. If total IFL utilization is close to 400%, then to give more
CPU to one linux server means higher weight for the LPAR, and higher
share for the linux server.

The other LPAR has 3 active IFL's. The fourth is offline.

How much of your IFLs are in use by the other LPAR(s)?

Can someone explain why CPU steal is? We believe that when the VM LPAR is using
almost all is IFL's CPU stealing begins between guests. But today this specific
LPAR has 4 IFL and is using 350% and one of the server, that has a one the
highest share is having a steal of 70%.
