====== Instalação: KVM e Terraform ======

==== Instalação do KVM ====
<code bash>
sudo apt install virt-manager libosinfo-bin mkisofs
</code>

<code bash>
sudo usermod -aG kvm $USER
</code>

<code bash>
$ mkdir -p /home/gean/kvm/images
$ mkdir -p /home/gean/kvm/templates
$ mkdir -p /home/gean/kvm/isos
</code>

<code bash>
$ virsh pool-define-as --name default --type dir --target /home/gean/kvm/images
$ virsh pool-define-as --name templates --type dir --target /home/gean/kvm/templates
$ virsh pool-define-as --name isos --type dir --target /home/gean/kvm/isos
</code>

<code bash>
$ virsh pool-autostart default
$ virsh pool-autostart templates
$ virsh pool-autostart isos
</code>

<code bash>
$ virsh pool-start default
$ virsh pool-start templates
$ virsh pool-start isos
</code>

<code bash>
$ virsh pool-list
</code>

<code bash>
$ virsh pool-info default
</code>

<code bash>
sudo chown libvirt-qemu:kvm /home/gean/kvm/images/ -R
sudo chown libvirt-qemu:kvm /home/gean/kvm/template/ -R
sudo chown libvirt-qemu:kvm /home/gean/kvm/isos/ -R
</code>

<file bash>
$ cat /etc/apparmor.d/libvirt/TEMPLATE.qemu 
#
# This profile is for the domain whose UUID matches this file.
#

#include <tunables/global>

profile LIBVIRT_TEMPLATE flags=(attach_disconnected) {
  #include <abstractions/libvirt-qemu>
  /home/gean/kvm/images/**.qcow2 rwk, /home/gean/kvm/images/**.img rwk,
  /home/gean/kvm/templates/**qcow2 rwk, /home/gean/kvm/templates/**img rwk,
}
</file>

<code>
sudo apparmor_parser -r /etc/apparmor.d/libvirt/TEMPLATE.qemu
sudo systemctl restart libvirtd
sudo journalctl -xe | grep apparmor
</code>

**Opção que desabilita a segurança**
<code bash>
$ sudo cp -p /etc/libvirt/qemu.conf{,.dist}
$ sudo sed -i '/#security_driver = "selinux"/a security_driver = "none"' /etc/libvirt/qemu.conf
$ sudo systemctl restart libvirtd
</code>

==== Instalação do Terraform ====
**Sistemas baseados em Debian**
<file bash>
sudo apt update
sudo apt install wget curl unzip
</file>

**Sistemas baseados em RedHat**
<file bash>
# sudo yum install curl wget unzip
</file>

<file bash>
TER_VER=`curl -s https://api.github.com/repos/hashicorp/terraform/releases/latest | grep tag_name | cut -d: -f2 | tr -d \"\,\v | awk '{$1=$1};1'`
</file>

<file bash>
wget https://releases.hashicorp.com/terraform/${TER_VER}/terraform_${TER_VER}_linux_amd64.zip
</file>

<file bash>
$ unzip terraform_${TER_VER}_linux_amd64.zip
</file>

<file>
$ sudo mv terraform /usr/local/bin/
</file>

<file>
$ which terraform
</file>

<file bash>
$ terraform --version
</file>

<file bash>
$ terraform -install-autocomplete
