Call Sysadmin: ***************************************************************************************************** How to configure Base System for KVM based Virtual machine and installing VM In Ubuntu 18.04 Requirements:
1. Ubuntu 18.04 LTS 64 bit Desktop System (you can use server too).
2. Minimum 8GiB RAM, 1TiB HDD and I/O MMU virtualization (AMD-Vi and Intel VT-d) Chipset.
3. Gigabyte Ethernet Adapter.
Verifying Hardware
Open a terminal and insert this command:
# lscpu In Output,if showing Virtualization: VT-x, then your Hardware support Virtualization. Installing required packages in base system:
Open a terminal and insert these commands:
# apt-get update
#apt-get upgrade -y
#apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils tightvncserver -y
Now Configure Bridge Network
For this, open a file /etc/network/interfaces
# vim /etc/network/interfaces
auto lo
iface lo inet loopback
#####################
auto lo
iface lo inet loopback
auto br0
iface br0 inet static
address YOUR IP ADDRESS
netmask YOUR SUBNET MASK
network YOUR NETWORK
broadcast LAST IP ADDRESS OF YOUR NETWORK
gateway YOUR GATEWAY
dns-nameservers 8.8.8.8
bridge_ports YOUR ETHERNET ADAPTER NAME
bridge_stp off
bridge_maxwait 0
Now create directories then create qcow2 file (Disk) and xml file.
# mkdir ~/vm; ~/vm/qcow2; ~/vm/xml
# qemu-img create -f qcow2 disk.qcow2 125G
Create a xml file for defining your Virtual system:
# vim ~/vm/xml/first_vm.xml
