From c6a77179a4097df355f0f04b8f3260c76b5e515c Mon Sep 17 00:00:00 2001 From: Ronny Chevalier Date: Sun, 8 Dec 2013 00:01:53 +0100 Subject: test: rework run_qemu It tries to find a suitable QEMU binary and will use KVM if present. We can now configure QEMU from outside with 4 variables : - $QEMU_BIN : path to QEMU's binary - $KERNEL_APPEND : arguments appended to kernel cmdline - $KERNEL_BIN : path to a kernel Default /boot/vmlinuz-$KERNEL_VER - $INITRD : path to an initramfs Default /boot/initramfs-${KERNEL_VER}.img - $QEMU_SMP : number of CPU simulated by QEMU.
