O vídeo do Youtube Instalando Linux usando o Virt-Manager mostra como se faz para instalar duas máquinas, cada uma contendo um Linux diferente sendo que as versões instaladas são: Debian 8 e CentOS 7. O hypervisor usado por padrão, no vídeo, é o kvm. Entretanto, o vídeo não comentou quais pacotes precisam ser instalados.
No Ubuntu Desktop 16.04 LTS, basta executar:
rlucca@millie:~$ sudo apt install -y virtinst_
O pacote virtinst deve fazer com que todas as dependencias necessarias sejam instaladas, alem disso a opção '-y' deve fazer com que em qualquer pergunta de confirmação a opção 'yes' (sim) seja escolhida automaticamente. Sendo assim, o comando virt-install, virt-manager e virsh estão instalados. O virt-install é mostrado a seguir.
rlucca@millie:~$ virt-install --version
1.3.2
rlucca@millie:~$ virt-install --help

- Não sei qual pacote instalar no Fedora/CentOS.
Utilize o YUM ou o DNF para listar qual pacote precisa ser instalado:
rlucca@millie:~$ sudo dnf provides '*/virt-manager'_
Ou
rlucca@millie:~$ sudo yum provides '*/virt-install'_
- Não sei qual pacote instalar no Debian/Ubuntu.
Utilize o DPKG para listar quais pacotes citam o texto "virt-manager":
rlucca@millie:~$ dpkg -S 'virt-manager'_
