Building micro stack Cloud, an OpenStack private cloud engine to replace, Proxmox, VMWare, and Citrix

Install microstack on Linux

sudo snap install microstack --beta

Now you can initiate microstack (OpenStack) with LVM-based Cinder

sudo microstack init --auto --control --setup-loop-based-cinder-lvm-backend --loop-device-file-size 1000

Now access your microstack and get password using below command

sudo snap get microstack config.credentials.keystone-password

Let’s fix the issue of the network interface so we can access OpenStack instances or VMs from the external network

sudo snap alias microstack.openstack openstack

sudo snap alias microstack.ovs-vsctl ovs-vsctl

Now add the bridge interface using ovs-vsctl

ovs-vsctl add-port br-ex eno2
ip addr flush dev eno2
ip addr add 192.168.18.100/24 dev br-ex
ip link set br-ex up

Now build a bridge interface using 2nd Network interface

vi microstack-br-workaround

#!/bin/bash
#
# Workaround to enable physical network access to MicroStack
#
# Adds the server physical ip address to br-ex.
physicalcidr=192.168.18.100/24
# Add IP address to br-ex
ip address add $physicalcidr dev br-ex || :
ip link set br-ex up || :

Now create a service to make persistent

vi microstack-br-workaround.service
[Unit]
Description=Service for adding physical ip to microstack bridge
Requires=snap.microstack.external-bridge.service
After=snap.microstack.external-bridge.service

SyslogIdentifier=microstack-br-workaround
Restart=no
WorkingDirectory=/usr/local/bin

Now use make them executable and copy them to the desired location

chmod +x microstack-br-workaround

chmod +x microstack-br-workaround.service

cp microstack-br-workaround /usr/local/bin

cp microstack-br-workaround.service /etc/systemd/system/

Now restart services

systemctl daemon-reload
systemctl enable microstack-br-workaround.service
