Maquina virtual Windows para ejecutar MATLAB
Instalacion en brick03
Ningun virtualbox o vmware. Voy a montar el kvm hypervisor de redhat que es lo que va a ir sin problemas en centos 7.
Tengo que instalar VNC server (para instalacion grafica de win),
[root@brick03 ~]# yum install tigervnc-server ...... OK! [root@brick03 ~]# yum install fluxbox ...... OK!
instalar qemu y libvirtd,
[root@brick03 ~]# grep -E '(vmx|svm)' /proc/cpuinfo ..... OK! [root@brick03 ~]# yum install qemu-kvm qemu-img virt-manager libvirt libvirt-python libvirt-client virt-install virt-viewer bridge-utils ...... OK!

Crear una maquina virtual, asignando la memoria, las CPU, el tamaño de disco, etc. La red debe ser el default. Windows se instala bastante bien. Configurar la red con DHCP. Activar Windows OK.
Hala, windoze en todo su esplendor,
A partir de aqui, estoy perdido. Instalo teamviewer y lo dejamos en manos de Lisot que son los que saben de esto
