Comment: changing network layout

First you need to setup libvirt's bridge adaptor, so we can bind the VMs network to have a default internet access via NAT on the VMs at creation.interfaces to it:

Code Block
bash
bash
root@hpc-admin # virshvim net-define /etc/libvirt/qemu/networks/default.xml
root@hpc-admin # virsh net-autostart default
root@hpc-admin # virsh net-start default
# Makesure it worked
root@hpc-admin # brctl show
# Make sure FORWARD works on rebootnetwork/interfaces
# auto enp0s25
# iface enp0s25 inet dhcp
auto br0
iface br0 inet static
	address 10.50.0.2
	netmask 255.255.0.0
	gateway 10.50.0.1
	dns-nameservers 10.50.0.1
	bridge_ports enp0s25
	bridge_stp off
	bridge_maxwait 0
	bridge_fd 0


root@hpc-admin # echo net.ipv4.ip_forward=1 > /etc/sysctl.confsystemctl restart networking

Then create 2 VMs : one for MrP, one for Jenkins.
