Estou na máquina host com o Centos 6.5, qemu + KVM e dois hosts virtuais (atrás do NAT). Ambos os hosts virtuais foram configurados com o Virtual Machine Manager (um deles é com o Windows 2003 e outro com o Centos 6.5), ambos têm memória RAM fixa (8GB e 4GB). Eu tenho 2 problemas / perguntas.
Se eu entrar em uma virt.machine e checar free -m, vejo que há muitos memes livres.
