Debian 8 Jessie | Gitian-Builder: start-target: qemu-system-x86_64: não encontrado

Question

Seguindo este guia: link

Estou usando o Gitian-builder para, espero, criar o script gitian-win.yml , que pode ser encontrado na íntegra detalhe aqui , usando o seguinte comando em:

/ home / gitian / gitian-builder

./bin/gbuild --commit testcoin=V1.0 ../testcoin/contrib/gitian-descriptors/gitian-win.yml

Saída:

************* WARNING: kvm not loaded, this will probably not work out

        from ./bin/gbuild:293:in 'each'
        from ./bin/gbuild:293:in '<main>'

Em seguida, verifiquei o log de depuração em /home/gitian/gitian-builder/var/target.log , que mostra o seguinte erro:

/home/gitian/gitian-builder/libexec/start-target: 27: /home/gitian/gitian-builder/libexec/start-target: qemu-system-x86_64: not found

Qual sugeriria que qemu_system-x86_64 não está na pasta, o que não é.

Quando eu verifico gitian-builder/libexec , a pasta contém o seguinte:

/home/gitian/gitian-builder/libexec# ls
config-bootstrap-fixup
config-lxc
copy-from-target
copy-to-target
gconfig
make-clean-vm
on-target
start-target
stop-target

Então, minha pergunta é: Como posso adicionar com sucesso qemu_system-x86_64 à pasta exigida para a meta inicial /home/gitian/gitian-builder/libexec ?
