On the host machine in the root of agent repository

go build -o ./bin/cocos-agent -ldflags="-linkmode=external -extldflags=-static -s -w" cmd/agent/main.go

Copy files to virtual drive

Shut down QEmu-alpine-standard-x86_64 virtual machine.

On the host machine

sudo apt-get install libguestfs-tools

QCOW2_PATH=~/go/src/github.com/ultravioletrs/manager/cmd/manager/img/boot.img

HOST_AGENT_PATH=~/go/src/github.com/ultravioletrs/agent/bin/cocos-agent; \
GUEST_AGENT_PATH=/root/; \
sudo virt-copy-in -a $QCOW2_PATH $HOST_AGENT_PATH $GUEST_AGENT_PATH

HOST_AGENT_PATH=~/go/src/github.com/ultravioletrs/agent/alpine/agent; \
