Estou usando o LinuxMint17 (host) e executando outro LinuxMint17 como convidado usando o Virtual Box.
Meu convidado LinuxMint é capaz de fazer ping no Host LinuxMint, mas vice-versa não está acontecendo.
Configuração de Rede no VirtualBox Adaptador de rede 1 - rede somente de host (isso eu fiz para que o IP de convidado estivesse alinhado com o host) Adaptador de rede 2- NAT (para obter meu trabalho de internet no convidado)

Alguém pode sugerir o que estou fazendo errado?
O que define o IP da interface eth0 no convidado? Não parece certo; os IPs devem estar na mesma sub-rede .
Experimente (no convidado, como root):
ip addr del 192.168.56.103/24 dev eth0
ip addr add 192.168.50.2/24 dev eth0
Isso excluirá o endereço IP existente e adicionará um que esteja na mesma sub-rede.
