Hi Fajar,

I *must* work with the latest version of SL 4.x (presently 4.7), I cannot avoid it. This is due to grid middleware requisites and technical support, otherwise I'm on my own to put grid services working.

So if I understood correctly from your post, a i386 domU running one of the latest RHEL like kernels, works fine on top of a x86_64 dom0. Thus, SL47 i386 domU will not probably run !!

Since I'm not at all proficient on kernel business, in order to avoid further problems probably I should stick to a i386 dom0.

My idea was to have these new servers running x86_64 on dom0, in case I'll need it in the future.

Cheers,
N.
