From 1038df14a96d789b3f9e9e1692305ba1fea67886 Mon Sep 17 00:00:00 2001 From: Scott Garman Date: Sat, 3 Sep 2011 15:50:30 -0700 Subject: runqemu: standardize ability to specify custom qemu/kenel boot options The old manner of specifying custom options to QEMU in this script using angle brackets was a frequent source of confusion. Meanwhile, Otavio Salvador added a decent method of specifying custom kernel boot options to this script. This patch documents the bootparams option and adds a similar way of specifying custom QEMU options using qemuparams="".
