[PATCH] virsh: simply printing of typed parameters

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



No need to repeat code for formatting typed parameters.

* tools/virsh.c (vshGetTypedParamValue): Support strings.
(cmdSchedinfo, cmdBlkiotune, cmdMemtune, cmdBlkdeviotune): Use
it for less code.
