Building a kernel with the z/VM recording device driver

7.1 z/VM guest

For a Linux® kernel that supports the z/VM® recording device driver you need a kernel that includes the IUCV device driver. Also, select the CONFIG_VMLOGRDR configuration menu option.

Kernel builders: This information is intended for those who want to build their own kernel. Be aware that both compiling your own kernel or recompiling an existing distribution usually means that you have to maintain your kernel yourself.
