Been testing Xen out, had the kernel-xen0-2.6.12-1.1454_FC4.i686.rpm dor dom0 and noticed I could not get more than 8 loop devices even with max_loop=32 passed. Looking at the kernel config the loop module was compiled into the kernel. Question - Can modules that are compiled into kernel have their parameters changed by passing options at boot? I am guessing no as that is what I have observed. Regards, Ted
