You'r right - RedHat built their kernel for stand-alone installation
only, requiring the use of the HMC integrated console, whereas VIF is
built to provide Linux images with a 3215 console. You need a kernel
with 3215 support to install under VIF.

Hi,
On Win32 and on other Unixes some compilers have possibilities to optimize
instruction scheduling in the compiler for Pentium pipeline architecture
etc...
Does anything like this exist in GCC, to optimize the instruction stream for
G4, G5 or G6 etc processors ?

You still have not answered the question of just how busy your S/390 CPU is

does not tell you anything about how busy the CPU is, only how many
processes are ready to run. Try bumping your QueueLA and RefuseLA on

We are having some problems at the moment geting iostat to output data
from the partitons defined to the system (e.g iostat -x /dev/dasdb).
This works OK on Redhat 7.2 and the reason for this seems to be that
/proc/partitions contains rather more information on RedHat than SLES7.
We tried
During the Distributions Redbook residency, the team installed SuSE, Red
Hat, Turbolinux, and Millenux in an LPAR, under VIF, and under VM. They all
worked (at that time). Since then, there have been numerous changes, and I
am not aware of anyone that has gone through the same exercise since.

Kernel updates from SuSE have the hooks for iostat to give info similar to

not
It is also my understanding that you have to buy another VM license to run guests
under your IFL engine when you get it. The IFL VM will have to talk to the NON-IFL VM
