[geeks] VMware and CentOS

[Ido Dubrawsky]

Well...the FullOn 2240 is an all SCSI machine.  SCSI takes the IO off 
the CPU's hands and puts it onto the SCSI controller. Modern ATA drives 
do something similar with DMA.  The minimum CPU spec for VMware server 
is a 733MHz or faster processor that supports the Pentium instruction 
set.  So, while the 1 GHz processors aren't the greatest, I don't think 
they're being overtaxed.  During startup of a virtual machine the CPUs 
get hit a bit but the overall load on the machine is not that much. 

I'm going to try your suggestion and to move some files around (6-10GB 
sized files) and see if that triggers the issue as well.
