Bring-Up User VM (L2 Guest)
***************************
1. Build the ACRN User VM kernel.
1. Build the User VM disk image (``UserVM.img``) following :ref:`build-the-ubuntu-kvm-image` and copy it to the ACRNSOS (L1 Guest).
Alternatively you can also use an `Ubuntu Desktop ISO image <https://ubuntu.com/#download>`_.
Rename the downloaded ISO image to ``UserVM.iso``.

cd ~/acrn-kernel
cp kernel_config_uos .config
make olddefconfig

#. Copy the User VM kernel to your home folder, we will use it to launch the User VM (L2 guest)

cp arch/x86/boot/bzImage ~/bzImage_uos
#. Build the User VM disk image (``UOS.img``) following :ref:`build-the-ubuntu-kvm-image` and copy it to the ACRNSOS (L1 Guest).
Alternatively you can also use ``virt-install`` **in the host environment** to create a User VM image similarly to how we built ACRNSOS previously.

Where ``<username>`` is your username in the Service VM and ``<IP address>`` its IP address.
