KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko. Run the below command to check whether the system supports virtualization:     # egrep -c  '(vmx|svm)' /proc/cpuinfo       16 If the above count is non zero, that indicates that system supports virtualization. Install 'cpu-checker' to make sure that your system is supported for KVM based virtualization.     # apt-get install cpu-checker -y Install all required package to configure KVM:     # apt-get install -y qemu qemu-kvm libvirt-daemon libvirt-clients bridge-utils virt-manager qemu-kvm: A software that provides hardware emulation for the kvm hypervisor. libvirt-daemon: A virtualization daemon that manages the lifecycle o...

Ansible is a great automation tool for infrastructure as a code and using ansible modules to automate VMware platform is really easy. In order to start the automation, need to configure a provision server where ansible and some of its dependencies need to be installed. A provision server can be on any operating system. But in this document we have focused on the following two opensource operating systems: Ubuntu 20.04 LTS CentOS 8.x  Following steps need to be performed to configure Ubuntu 20.04 LTS as a provision server: a. Install python3-pip:     # apt-get  install  python3-pip  -y    Upgrade pip3 to the latest version:   # pip3  install  --upgrade  pip b. Install & check latest ansible  version:       # pip3 install ansible   # pip3 show ansible      c.  Install & check  pyVmomi :       # pip3 install pyvmomi ...

1. Install all the required KVM packages:    # apt install qemu-kvm libvirt-clients libvirt-daemon-system bridge-utils virt-manager   -y 2. Start and enable 'libvirtd' daemon:    # systemctl start libvirtd     # systemctl enable libvirtd    # systemctl status libvirtd 3. Login to the KVM host using console or do SSH:    ➤  ssh -l root kvmhost.example.com    The default config file will look like below: # cat  /etc/netplan/50-cloud-init.yaml network:     ethernets:         eno1:             addresses:             - 192.168.0.3/24             dhcp4: false             gateway4: 192.168.0.1             nameservers:                 addresses:       ...

xRDP is one of the most commonly used opensource remote desktop protocol (rdp). By following the below steps it can easily be configured on different flavors of Ubuntu system. Configuration : a. Login to the Ubuntu server as 'root' and run the update: # apt-get update && apt-get upgrade -y b. Install the 'xfce4' desktop environment: # apt-get install xfce4 xfce4-goodies -y c. Install the 'xrdp' package: # apt-get install xorgxrdp xrdp -y d. Enable the 'xfce4-session' for both 'ubuntu' and 'root' user: # echo xfce4-session >~/.xsession # su - ubuntu $ echo xfce4-session >~/.xsession Now the system is ready. You can login to the system using RDP via 'root' or 'ubuntu' user along with their own password. NOTE : If 'ufw' is enabled, make sure to allow the network access to RDP this system. To check the 'ufw' status: # ufw status To allo...
