I guess VMware has no relationship with IBM VM.
I'll write one phenomina that will help you understand background.
VMware offered free test to IBM'ers that had VMware licence already about
three month ago.
I had VMware licence and joined the evaluation test, because I'm interested
in GSX server.
The candidate VMware product are GSX server 1.0 (for Win2000 & Linux), as
well as VMware workstation 3.0 (for Win2000 & Linux).
I downloaded their products and our Linux team did some testing. I'll
write down our feeling about VMware.
1. VMware is not the Hipervisor, instead it looks like piggy-back
middleware that simulate Guest operating system running on Intel
architecture. Hence, VMware has different version for Win2000 and Linux.
Also, it requires a certain Base Operating Release level.
For example, VMware GSX server did support Redhat 7.1, but does not support
7.2. We tried Redhat 7.2 and had to modify one module vmmon.tar . (one of
our Linux specialist modified it)
2. VMware gives good CPU efficency, but memory move is slow. We don't test
I/O.
I just write some piece of measurement. OS are Redhat Linux 7.2, host
means 'native Linux' and guest means 'Linux running on VMware that is
running on native Linux'. Machine is Pentium3/1GHz Dual with 1.5 GB SDRAM
memory.
