Mastering Proxmox - Third Edition

By: Wasim Ahmed

Overview of this book

Proxmox is an open source server virtualization solution that has enterprise-class features for managing virtual machines, for storage, and to virtualize both Linux and Windows application workloads. You'll begin with a refresher on the advanced installation features and the Proxmox GUI to familiarize yourself with the Proxmox VE hypervisor. Then, you'll move on to explore Proxmox under the hood, focusing on storage systems, such as Ceph, used with Proxmox. Moving on, you'll learn to manage KVM virtual machines, deploy Linux containers fast, and see how networking is handled in Proxmox. You'll also learn how to protect a cluster or a VM with a firewall and explore the new high availability features introduced in Proxmox VE 5.0. Next, you'll dive deeper into the backup/restore strategy and see how to properly update and upgrade a Proxmox node. Later, you'll learn how to monitor a Proxmox cluster and all of its components using Zabbix. Finally, you'll discover how to recover Promox from disaster strikes through some real-world examples. By the end of the book, you'll be an expert at making Proxmox work in production environments with minimal downtime.

Preface

Network connectivity issues


This section contains issues related to virtual or physical network connectivity within Proxmox.

Issue – no connectivity on Realtek RTL8111/8411 rev. 06 network interfaces

Some newer Realtek chipsets don't get compiled with the right drivers. This causes the interface to be up without any network traffic. In order to fix this issue, the older driver needs to be downloaded from the Realtek site and compiled manually. The driver can be downloaded from http://www.realtek.com.tw/Downloads/.

Since this driver is manually installed, during a kernel update it will get updated automatically. To prevent this and ensure that the driver builds itself automatically when a new kernel is installed, run the following commands and then reboot the node:

# apt-get install dkms build-essential pve-headers-4.10.15-pve
    # mkdir /usr/src/r8168-8.037.00
# cat << EOF > /usr/src/r8168-8.037.00/dkms.conf
