Re: ldomctl (still?) not generating usable configurations

Hi Claudio,

just tried again to the same result: I deleted the quotes from the ldom
names, re-built and downloaded the new configuration to the SP as described
in the manual, then from the SP 'reset -c'. The machine *never* boots after that. In fact,
the 'reset -c' command takes me to the console but the video output just freezes,
and then it won't even let me go back to the system console with the '#.' combination.

Feeling lost now - this box has 32GB RAM so that really shouldn't be a problem. I have
a T5120 as well and I will try to setup ldoms there and hopefully be able to share
something positive.

Thanks for your help!
