That probably explains why we may never see it run on Solaris x86. :-(

Only the future will tell ...
OKay .. I'm done with this phase of this document. I have all the
images and I have the virtual server running fine and I even applied
the /var/svc/profile/generic_limited_net.xml service profile.
If I login via ssh I can even get the processor state and change the
state as per usual :
# psrinfo -v
Status of virtual processor 0 as of: 01/30/2006 22:28:07
on-line since 01/30/2006 21:59:27.
The i386 processor operates at 2391 MHz,
and has an i387 compatible floating point processor.
Status of virtual processor 1 as of: 01/30/2006 22:28:07
on-line since 01/30/2006 21:59:30.
The i386 processor operates at 2391 MHz,
and has an i387 compatible floating point processor.
Take processor 1 offline :
# psradm -f 1
# psrinfo -v
Status of virtual processor 0 as of: 01/30/2006 22:28:38
on-line since 01/30/2006 22:28:28.

off-line since 01/30/2006 22:28:34.
The i386 processor operates at 2391 MHz,
and has an i387 compatible floating point processor.
Then back online
# psradm -n 1
Then mark proc 1 as spare :
# psradm -sv 1
processor 1 marked spare.
# psrinfo -v

We have memory :
# prtconf -v | grep Memory

# df -ak

Now it will be fun to create a zone in there.
I wonder how I create another disk ? Hmmm .. that could be interesting.
