The build is done with the devices file:
CONFIG_PCI_DEVICES=n
CONFIG_MICROVM=y
CONFIG_VIRTIO_BLK=y
CONFIG_VIRTIO_SERIAL=y
CONFIG_VIRTIO_INPUT=y
CONFIG_VIRTIO_INPUT_HOST=y
CONFIG_VHOST_USER_INPUT=y
CONFIG_VIRTIO_NET=y
CONFIG_VIRTIO_SCSI=y
CONFIG_VIRTIO_RNG=y
CONFIG_VIRTIO_CRYPTO=y
CONFIG_VIRTIO_BALLOON=y
CONFIG_VIRTIO_GPU=y
CONFIG_VHOST_USER_GPU=y
and with these confiure options:
../../configure ${common_configure_opts} \
--without-default-features \
--target-list=x86_64-softmmu --enable-kvm --disable-tcg \
--enable-pixman --enable-vnc \
--enable-virtfs \
