Open a PowerShell console in the VM folder (Left Shift + Mouse Right Click on Windows) Quick list and check on the files.

In this post I'm sharing how to address of the most repetitive tasks after fresh build or clone a VM. Eg. for database   pre install tasks . First of all , I will how to change the hostname. Next, I will setup the local naming resolution. At end, how to play with the firewall. Change hostname - the hostname is key including for server provisioning and orchestration, the server name can be changed using the hostnamectl command. Lets see bellow some examples. root@Unknown-08-00-27-26-48-7d # hostnamectl status Static hostname: localhost.localdomain Transient hostname: Unknown-08-00-27-26-48-7d Icon name: computer-vm Chassis: vm Machine ID: d5a9e3e4d118804089e345228a189582 Boot ID: f76e3fc1c76f49028a1583b90eb01511 Virtualization: kvm Operating System: Oracle Linux Server 7.7 CPE OS Name: cpe:/o:oracle:linux:7:7:server Kernel: Linux 4.14.35-1902.3.2.el7uek.x86_64 Architecture: x86-64 root@Unknown-08-00-27-26-48-7d # hostnamectl set-hostname wls.example.com root@Unknown-08-00-27-26-48...

Versão Portuguesa Sometimes is useful to have two operative systems in the laptop, is possible to get that creating two partitions in th disk, and to install the OS in the respective partition. But this post is not about that - this post is about .. after have the installation is done. After install Linux, is expectable to have a menu to select the operative system. That didn't happened in my latptop, it's loading directly the Linux .. upss Windows 10 "has gone" !!! This post is about that .. feature

EnglishVersion Por vezes e interessante ter dois sistemas operativos numa maquina. Isso consegue-se particionando o disco, e instalar o sistema operativo noutra partição.Este post não e sobre essa instalação, mas sim sobre pós configuração. Apos instalar Linux, quando inicio o portátil e espectável aparecer um menu para selecionar o sistema operativo, Linux ou Windows 10 ... No meu caso o portátil carrega diretamente o Linux .. upss o Windows 10 "desapareceu" !!! Este post partilho a investigação sobre isso .
