Be careful when using Gentoo to compile the kernel

When compiling the kernel, use genkernel-general Linux technology-Linux programming and kernel information carefully. For more information, see the following. This installation of Gentoo, when compiling the kernel, is not manually configured, but directly uses the genkernel all command to generate the kernel file, which saves a lot of trouble. however, an error was reported when emerge nvidia-drivers was followed. The log showed that Paravirtualized guest support was compiled. You can only manually make menuconfig to remove the corresponding items in Processor type and features. looking at other modules, I felt that the automatic configuration was not good. I chose a lot of irrelevant and useless modules and had to remove them one by one. it seems that this most tedious step cannot be simplified.
