booting Linux inside MOL (was RE: mac-on-linux freeze)

[Greg Alexander]

Two words: Workload consolidation.

This is incredibly useful, and is what IBM does with LOTS of their
servers.

If the performance is good, you can run two linux installations on the
same machine, (say, your database and your web server), and they get the
advantages of VERY high speed networking, workload balancing, etc.,
while keeping many of the advantages of running them on different
servers.

This takes some tweaking to get right, but can be a big deal if you run
a several servers that you don't want on the same system, but tend to
have different peak times, or where communication overhead is the
primary bottleneck.

Basically, the parent linux is there to provide resources to the child
linux installations.

It's also very useful to people like kernel developers and others who
need a way to look at the nitty gritty of what's going on, beyond what
is normally available on real hardware.



This makes me wonder, can multiple instances of MOL run on the same
machine?

Thanks,

GREG
