Hi,
yes, using non-smp kernels disables HyperT, but I've noticed that at
boot the non-smp kernel "sees" always the second CPU (but disables it
anyway), so usually I prefer to disable HyperT from the BIOS.
Anyway, I'll try 2.6.12 as soon as possible.
Just a question: how much is different the ipvs kernel daemon between
2.4.x and 2.6.x ?
Thank you very much for your answers, I'll report on the list after my tests :-)
Kind regards,
Luca
