+How to use this package
+
+1. Build an image with a defconfig containing
+
+BR2_x86_64=y
+
+BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_EUDEV=y
+BR2_PACKAGE_BUSYBOX_SHOW_OTHERS=y
+
+BR2_PACKAGE_QEMU=y
+BR2_PACKAGE_QEMU_CUSTOM_TARGETS="x86_64-softmmu"
+BR2_PACKAGE_QEMU_SLIRP=y
+
+BR2_PACKAGE_LIBVIRT=y
+BR2_PACKAGE_LIBVIRT_QEMU=y
+BR2_PACKAGE_TEST_VM=y
+
+For remote accesss you will need an SSH server
+
+BR2_PACKAGE_DROPBEAR=y
+BR2_PACKAGE_DROPBEAR_DISABLE_REVERSEDNS=y
+
+Ensure that the kernel configuration has
+
+CONFIG_VFIO=m
+CONFIG_VFIO_PCI=m
+CONFIG_VFIO_MDEV=m
+CONFIG_VFIO_MDEV_DEVICE=m
+CONFIG_VHOST_NET=m
+CONFIG_VHOST_VSOCK=y
+CONFIG_TUN=m
+
+The rootfs size must be arount 100MB for a sysvinit/busybox init system and
+200MB for a systemd system.
+
+Configure the OS to obtain an IP address, either statically or via DHCP.
+
+2. Boot and log in as root, then run
+
+ # virsh define /etc/vm-templates/test-xm.xml
+ # virsh start test-vm && virsh console test-vm
+
+Leave the vm console by hitting ^]
+
+Shutdown the vm
+
+ # virsh shutdown test-vm
+
+3. Access the vm remotely using virt-manager
+
+On a machine with virt-manager installed, open it and create a new connection.
+Supposing that the host IP address is 192.168.2.2:
+
+ File->Add Connection
+
+ Name: QEMU/KVM on 192.168.2.2
+ Libvirt URL: qemu+ssh://root@192.168.2.2/system
+
+Double-click on the connection and provide the root user password. A "test-vm"
+item will appear (supposing that you wen through step 2, above). Double-click
+on it. Use the vm window to play with it.
+
+Have fun!
