About running qemu/kvm

[tonglin]

I have built my own Image(arm64), system.img and ramdisk.img successfully. I refer to https://github.com/robherring/generic_device/wiki/Running-QEMU-KVM
for how to run qemu, here is my script:

#!/bin/sh -e
if [ -n "$1" ]; then
INSTANCE_ID=$(printf "%02d" $1)
INSTANCE_DIR=run-${INSTANCE_ID}
mkdir -p ${INSTANCE_DIR}
shift
else
echo "Must specify instance id"
exit 1
fi

ANDROID_IMAGE_PATH=./

if [ ! -f ${ANDROID_IMAGE_PATH}/system.img ]; then
echo "Missing system.img"
exit 1
fi

QEMU_ARCH=$(arch)

QEMU_DISPLAY="-device virtio-gpu-pci,virgl -display gtk,gl=off"

QEMU_OPTS="-machine virt,gic-version=host -cpu host -smp 4 -enable-kvm"
KERNEL_CMDLINE='console=ttyAMA0,38400'
KERNEL=Image

if [ ! -f system.raw -o ${ANDROID_IMAGE_PATH}/system.img -nt system.raw ]; then
simg2img ${ANDROID_IMAGE_PATH}/system.img system.raw
fi

if [ ! -f ${INSTANCE_DIR}/cache.raw -o system.raw -nt ${INSTANCE_DIR}/cache.raw ]; then
rm -f ${INSTANCE_DIR}/*.raw
mkfs.ext4 -L cache ${INSTANCE_DIR}/cache.raw 128M
mkfs.ext4 -L data ${INSTANCE_DIR}/userdata.raw 512M
fi

../myqemu/bin/qemu-system-${QEMU_ARCH}
${QEMU_OPTS}
-append "${KERNEL_CMDLINE} vt.global_cursor_default=0 androidboot.selinux=permissive debug drm.debug=0 qemu=0"
-m 2048

-nodefaults
-serial stdio
${QEMU_DISPLAY}
$*

while output of console keeps printing the following logs, I wonder how can I fixed this and how can I get the display with h/w rendering since vnc or spice not supported on h/w rendering.

If surfaceflinger is exiting, you need to look at logcat and see why.

Also, virgl still requires out of tree patches for kernel and mesa for explicit fence support. Make sure you have those.

@robherring I refer https://github.com/robherring/generic_device/wiki/Building for the steps, and my qemu can run successfully, android desktop can be seen, but mouse input is broken, I can't see it in vnc window. My GTK is 3.18 and the method to force ‘gtk_gl=”no”' doesn't work for me, I wonder what can I do to solve the problem?
