libvirt-add-new-api-demo

ABOUT

This patch is an example to add new APIs in LibVirt, also add entries in virsh. I implement qemu driver only but others are the same.

USAGE

git clone https://github.com/Arondight/libvirt-add-new-api-demo.git
git clone https://github.com/libvirt/libvirt.git
git clone https://github.com/coreutils/gnulib.git
export LIBVIRT_PATCH=$(readlink -f ./libvirt-add-new-api-demo/LibVirt-add-new-API-demo.patch)
export GNULIB_SRCDIR=$(readlink -f ./gnulib)
cd libvirt
git checkout v2.5.0
git am $LIBVIRT_PATCH
./autogen.sh
make -j8
make check -j8

SYNOPSIS

There are 3 new commands in virsh:

1. get-magic: Get magic file's content

• set-magic: Set magic file's content
• magic-status: Show if magic file can be read

You can run virsh via run to try these.

First start libvirtd in a new console with root privilege.

sudo ./run ./daemon/libvirtd

Then set or get magic file's content.

sudo ./run ./tools/virsh set-magic 'Hello World!'
sudo ./run ./tools/virsh get-magic

If you set magic file's content to 0xabadcafe, QEMU driver will refused to boot any VM.

sudo ./run ./tools/virsh -c qemu:///system set-magic '0xabadcafe'
sudo ./run ./tools/virsh -c qemu:///system start <domain>
