Just noticed an interesting quirk with VMWare Server and hyper threading CPUs

I told my VM to use 1 CPU but CentOS 4 install detected the underlying hardware CPU had hyper threading so installed the SMP kernel !

Linux localhost.localdomain 2.6.9-67.0.15.ELsmp #1 SMP Thu May 8 10:52:19 EDT 2008 i686 i686 i386 GNU/Linux

as opposed to creating a VM where underlying hardware didn’t have hyper threading where CentOS 4 install just installed the basic kernel !

Linux localhost.localdomain 2.6.9-67.0.15.EL #1 Thu May 8 10:39:19 EDT 2008 i686 i686 i386 GNU/Linux

There is an OpenVZ live-CD VZ VM server with VZ VM guests (based on CentOS or KNOPPIX) that you can download from http://wiki.openvz.org/Download_live_CD

And there is a quick start guide to read at http://wiki.openvz.org/Getting_started_with_OpenVZ_live_CD
