Examples for kernel parameters

6.10 LPAR mode z/VM guest KVM guest

Typical parameters that are used for booting Linux® on IBM® Z configure the console and the root file system.

conmode=<mode>, condev=<cuu>, console=<name>
to set up the Linux console.
noinitrd
to suppress an initial RAM disk. Specify this parameter if your boot configuration includes an initial RAM disk but you do not want to use it.
ramdisk_size=<size>
to specify the size of the initial RAM disk.
ro
to mount the root file system read-only.
root=<rootdevice>
to specify the device to be mounted as the root file system.
dasd=<devices>
to make specific DASDs available to the boot process.

This kernel parameter applies only if the DASD device driver is compiled into the kernel image. If your DASD device driver is a separate module, use the dasd= module parameter instead.

Exception: You can specify dasd= with the kernel parameters if your distribution makes special provisions to interpret it on the kernel parameter line.
Alternative: You can use dasd_mod.dasd= on the parameter line. With the notation <module>.<module_parameter>, you can pass module parameters through the kernel parameter line.
